Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to solid compositions and methods for conditioning textile products in domestic washing operations.

Throughout the entire washing process (through-the-w)
Disclosed herein are compositions and methods for conditioning textile products during the rinse cycle of ashlaundering operations and home washing operations.

It imparts a texture or texture that is smooth to the touch, soft and fluffy (i.e., pliable) to a washed textile product, and also particularly when the textile product is dried in an automatic dryer. It is common practice to reduce the tendency of electrostatic charges to build up and/or retain (ie, electrostatic regulation).

In recent years, it has become common for housewives to use fiber conditioning compositions.

It is common practice to use a fiber conditioning composition that consists of mostly water, a small amount of fiber conditioner, and small amounts of optional ingredients such as fragrances, colorants, preservatives, and stabilizers during the rinsing cycle. It is true.

Such compositions can be conveniently added to the baths of home washing operations.

Another method is to provide a cleaning composition containing a fiber conditioner, which conditioner adheres to the textile and is transported through the wash and rinse cycle to impart the fibers to the dry textile. Provides regulating properties.

BACKGROUND OF THE INVENTION The use of organic cationic fabric softeners is known.

U.S. Pat. No. 3,095,373 describes at least one
Cationic compounds containing at least one hydrophobic chain having 6 carbon atoms are disclosed.

It is also known to use clay as a softening agent.

A wide variety of clays have been suggested over the years for use in detergent compositions.

For example, British Patent Nos. 401.413 and 401.413
No. 61,221 discloses the use of colloidal bentonite in built or unbuilt synthetic detergent compositions intended for use in cleaning hair, textiles or hard surface equipment. .

More recently, British Patent No. 1,400,898 describes the use of smectites in built detergent compositions.
The use of clay (smectite) to impart softening to textiles during general washing operations has been disclosed.

GB 1,401,726 discloses the use of these clays in soap compositions containing small amounts of synthetic detergents as curd dispersants.

Other prior art documents describe the use of clay in cleaning compositions with other effects such as builders, water softeners, anti-caking agents, suspending agents, stain release agents, hair washes, and fillers. It has been disclosed that

It is also known to use clay and organic cationic fiber softening ingredient formulations in detergent compositions to simultaneously clean and soften textiles, in addition to other auxiliary effects such as electrostatic regulation. .

U.S. Pat. No. 3,886,075 discloses certain smectite clays, cationic antistatic agents, which are compatible detergents and impart softening and antistatic effects to textiles washed therewith. Compositions containing substituted amino coexisting agents of the type consisting of and are disclosed.

No. 3,948,790 discloses detergent compositions containing short chain quaternary ammonium clays that are effective in imparting fiber softening with nonionic detergents.

In general, although the clay that it consists of imparts flexibility to the fibers,
It has been recognized that such softening is of a dry feel nature and is limited to the softening performance associated with conventional organic cationic fiber softeners.

Although organic cationic softeners impart a desirable soft and smooth feel to textiles, their use
It is typically limited to those compounds that are easily soluble/dispersible in the housewife's washing routine and have an affinity for adhesion to textiles.

Organic cationic softening chemicals within these ranges are incompatible with anionic surfactants.
1ble) and have therefore commonly been used in rinsing processes or in mechanical dryers.

Because of this non-coexistence, the softening performance in the rinse step appears to be a function of the anionic detergent transferred from the wash step.

Moreover, this performance tends to change easily. It is an object of the present invention to provide complex forms which can be used in anionic surfactant-containing detergent compositions for fabric softening during rinsing operations or throughout washing operations.
rm) clay and an organic fiber softener.

DISCLOSURE OF THE INVENTION The present invention relates to solid detergent compositions for use in household washing operations.

This detergent composition consists of a textile product conditioning composition and a cleaning composition, and this textile product conditioning composition consists of the following three main components.

That is, (a) at least 50 milliequivalents (maq)/1o
(b) an organic primary, secondary, and tertiary amine in an amount of from about 1 to about 50% by weight of the clay; water-soluble or water-dispersible salts thereof, and compounds selected from the group consisting of organic quaternary ammonium, phosphonium and sulfonium compounds, in which these compounds contain at least one hydrocarbon of 8 to 22 carbon atoms. and (c) a wetting and dispersing agent selected from the group consisting of electrolytes, anionic surfactants, and mixtures thereof, having a solubility in water of at least about 7 parts per 100 parts of water at 20°C; wherein the electrolyte as described above, when present alone, is present in an amount of from about 10 to about 90%, and the anionic surfactant as described above, when present alone, relative to component (b). present in an amount of at least 30% molar equivalent, and components (a) and (b) above are combined to form an organic fiber softener-clay composite.
lex).

The organo-clay softener composite is hydrophobic and the wetting and dispersing agent is effective in dispersing the fiber softener composite so that good adhesion to textiles is achieved and is therefore desirable. It has been unexpectedly found that good and durable fiber softening performance with smooth properties is obtained.

Such textile conditioning compositions may be combined with about 1 to about 50% surfactant; and (11) about 10 to about 60% by weight of an organic or inorganic bilter salt. can be obtained.

Furthermore, with the compositions of the invention an improved removal of oily/greasy stains from textile products (% polyester products) treated with the compositions is achieved.

DETAILED DESCRIPTION OF THE INVENTION The composition for preparing textile products used in the detergent composition of the present invention will be described below.

Clay The first of the three main components of the present invention is smectite clay (
smectite clay).

The clay is complexed with organic fiber softeners to provide textile conditioning benefits.

The smectite clay is about 10 to about 8 by weight of the composition.
present in the particulate fiber conditioning composition in an amount of 0% and preferably from about 20% to about 60%.

The clay mineral used to provide some of the softening properties of the compositions of the present invention can be described as a finely expanded trilayer clay.

In the clay, one sheet layer of aluminum/oxygen atoms or magnesium/oxygen atoms has two layers of silicon/oxygen atoms.
Exists between layers.

That is, the clay contains at least 50 m/100 g of clay.
Alumino-silicates and magnesium silicates with an ion exchange capacity of eq.

The term " used to describe the clay used in the present invention"
The term impalpable means that the individual clay particles are of a size that is not perceptible to the senses of touch.

Such particle sizes are in the range of less than about 100 microns in effective diameter.

Generally, the clays used in the present invention have ultimate particle sizes within the range of about 1 to about 50 microns.

"Expandable" used to describe clay
e) The term J relates to the ability of the layered structure of the clay to swell or swell upon contact with water.

The three-layer expansive clay used in the present invention is an example of clay minerals that are geologically classified as smectites.

There are two different types of smectite clays that differ widely based on the number of metal-oxygen octahedral arrangements in the central layer relative to the number of silicon-oxygen atoms in the outer layer.

Double octahedral minerals are mainly trivalent metal ion-based clays, and are the prototype pyrophyllite.
te) and the following minerals, namely montmorillonite (
(OH)4Si8
- AI (AI4-xMg)002o, montronite (OH)4Si8-AI(A1.-xFex)02o,
and volchonskoite
)(OH)4Si8-yAly(AI4-xCrx)0
2o (here, X has a value of O to about 4.0, and y is O
(having a value of approximately 2.0).

Among these, only montmorillonite with an exchange capacity greater than 50 meq/100 f1 is suitable for the present invention and provides a fiber softening effect.

The triple octahedral mineral is mainly of divalent metal ion type, and contains the original talc and the following minerals: hectorite (OH)4S i,
, AI, (Mg, -xLix) 02o, saponite (OH)4 (S i, -yAly) (Mga -X

, vermiculite (
OH)4 Sig + AI (Mga -x”ex
) o20 (where y has a value of O to about 2.0 and X has a value of 0 to about 6.0).

Hectorite and sabonite are the only minerals of this type of value in this invention.

Static reduction of fiber softening performance is related to the type of exchangeable cations as well as the exchange capacity.

Smectite clays useful in the present invention are hydrophilic in nature, ie, exhibit the property of swelling in aqueous media.

It should be appreciated that the range of water of hydration in the above formula may vary depending on the process to which the clay is processed.

This is not important for the use of the smectite clays of the present invention since the swelling properties of hydrated clays are dominated by the silicate lattice structure.

As mentioned above, the clay mineral used in the composition of the present invention contains cationic counterions such as protons, sodium ions, potassium ions, calcium ions, magnesium ions, and lithium ions.

It is customary to distinguish clays on the basis of one cation that is preferentially or exclusively absorbed.

For example, a sodium clay is a clay in which the predominant cation absorbed is sodium.

Such absorbed cations can involve exchange reactions with cations present in the aqueous solution.

A typical exchange reaction involving smectite clay is expressed by the following formula.

Smectite clay (Na) + NH40H = Smectite clay (NT(4) + NaOH) In the above equilibrium reaction, 1 equivalent weight of ammonium ion replaces 1 equivalent weight of sodium, so milliequivalents per ioog of clay (me q/100. !9) It is customary to measure the cation exchange capacity (also called base exchange capacity j).

The cation exchange capacity of clays can be measured by a variety of methods, including electrodialysis, ammonium ion exchange followed by titration, or the methylene flue method.

These methods are described in "The Chemistry and Physic" written by Grimshaw.
s of Clays J, pages 264-265.

The cation exchange capacity of clay minerals is related to factors such as the swelling properties of the clay, the charge of the clay, which are determined at least in part by the lattice structure and the like.

The ion exchange capacity of clays varies widely over a range of about 2 meq/10011 or more, and in the case of kaol 1nites it is about 150 meq/10011 or more.
q/Ion, and even more in the types of smectite clays.

Illite clays, although having a three-layered structure, are of the non-expansive lattice type and have an ion exchange capacity in the lower region of this range, i.e. a capacity of about 26 meq/10011 for the average illite clay. .

Another type of clay mineral, acpargite (atta
pulgites) have a low exchange capacity (25-30me
q/100. ! ? ) has needle-like crystals.

These structures are composed of silica tetrahedral silver interconnected by octahedral groups of oxygen and hydroxyl groups containing AI and Mg atoms.

Illite, attapulgite and kaolinite clays with relatively low ion exchange capacities were determined not to be useful in the compositions of the present invention.

However, the alkali metals montmorillonite, saponite and hectorite, and alkaline earth metal modifications of the class consisting of these minerals, such as calcium and sodium montmorillonite, are effective when included in the composition according to the invention. It was found that it exhibits a fiber softening effect.

Specific examples of such smectite clay minerals for fiber softening are as follows, but are not limited thereto.

Sodium montmorillonite block (Block) Volclay BC (Volclay BC) Gelwhite GP (Gelwhite GP) Thigsodiel +

) Most of the smectite clays useful in the present invention are manufactured by, for example, Th1xo-Je from Georgia Kaolin.
Volclay BC and Volclay 4J- from Amer 1can Col 1oid under trade names such as 1#1 and Qel wll iteG P.
325 under the trade name, and R, T, Vanderb.
It is commercially available from ilt under the trade name Veegum F.

It should be recognized that the smectite minerals available under the above trade names may consist of a mixture of each type of separate mineral matter.

Such mixtures of smectite minerals are suitable for use in the present invention.

Among the clay mineral classes of montmorillonite, hectorite and saponite having a cation exchange capacity of at least about 50 meq/100.9, clays of the following class are preferred for fiber softening purposes.

For example, Gelwhite GP is a very white form of smectite clay and is therefore preferred when blended with white or slightly colored aggregates.

Volclay BC is a smectite clay mineral containing at least 3% iron (as Fe203) in the crystal lattice and has a very high ion exchange capacity, but
It is one of the most efficient and effective clays for use in agglomerated fiber conditioning compositions and is preferred from a product performance standpoint.

On the other hand, smectite clays of the type marketed under the name bentonite J are heavily contaminated with other silicate materials, as indicated by their low colloid content (approximately 50%), and are highly contaminated with ionic materials. Replacement capacity is lower than required range.

Such clays are not useful in the compositions of this invention.

In fact, bentonite is a rock type formed from volcanic ash and contains montmorillonite (a type of smectite clay) as its main clay component.

The table below shows that materials commercially available under the name bentonite have a wide range of cation exchange capacity and fiber softening performance.

Mixtures of two or more clays are within the scope of this invention.

It has also been found that the smectite minerals comprising the composition can reduce or eliminate the buildup of static electricity on textiles washed in the composition.

Visible evidence that static electricity buildup has been prevented is the absence of "cling, J", ie the tendency of different parts of the textile to stick to each other.

The measurement for static charge dissipation is the average voltage of the textile.

Smectite clays that have been found to be effective in reducing static charge build-up when included in agglomerated fiber conditioning compositions include lithium and magnesium hectorite and saponite, respectively (OH).
s5ia-y"y(Mga-xLix)02o and (OH)4SIB-8AI, Mg6-xAl
It is a mineral with the structure x02o.

In the above formula, the counter ions are mainly magnesium or lithium, ie at least 50% of the counter ions are Li 2 or Mg 2 and the remainder are other alkaline earth metal or alkali metal counter ions.

Preferred minerals have a counter ion of lithium or magnesium and an ion exchange capacity of 60 meq 7100 g
It is a larger mineral.

Examples of such preferred materials include magnesium hectorite, lithium hectorite and magnesium saponite.

The wide range of effects provided by Mg and Ll hectorite and saponite clay minerals is believed to be related to the number-to-charge ratio of these cations and the usually large number of moles of water that can be retained in the minerals.

Minerals with fiber softening properties such as sodium and calcium montmorillonite and sodium hectorite and saponite do not exhibit antistatic activity to any appreciable extent.

Magnesium montmorillonite also does not exhibit this activity.

Accordingly, the smectite viscosities useful in the fiber conditioning compositions of the present invention can be characterized as montmorillonite, hectorite and saponite clay minerals having an ion exchange capacity of at least about 50 meq/7100 g and preferably at least 60 meq/1009 g. .

Suitable clay minerals used in the present invention include smectites with 1
The selection can be made based on the fact that four people have true X-ray diffraction patterns.

This characteristic diagram, in combination with ion exchange capacity measurements performed in the manner described above, provides criteria for selecting particular smectite minerals for use in the particulate fiber softening compositions disclosed herein.

The above-mentioned smectite clays are deposited on the fiber surface and especially on the negatively charged cotton surface.
), it functions as a fiber conditioner.

The clay is effective not only on IOO% cotton textiles, but also on blended textiles containing significant amounts of cotton, such as 50% cotton and 150% polyester blends.

Separated individual smectite clay particles are in the shape of flat platelets and have a predominantly positive charge around the edges where the crystal lattice is incomplete and a predominantly negative charge on their flat sides. .

Organic Fiber Softener The second essential component of the present invention is an organic fiber softener that reacts with the clay to form a water-insoluble composite.

The organic fiber softener is included in one of the clay components in the composition of the present invention.
Present in an amount of ~50%.

The preferred amount range is 3-30% of the clay component, most preferably 5-20%.

Generally, useful softeners are organic compounds that are primary, secondary, tertiary, or quaternary nitrogen-containing organic compounds, or phosphonium compounds or sulfonium compounds, and that have relatively long lengths that impart hydrophobicity and smoothness. A compound having at least one hydrocarbon substituent in the chain.

Typical textile softeners include the following:

A. Primary, secondary and tertiary amines and their water-soluble or water-dispersible salts and quaternary ammonium compounds.

The general formula of this group is R,R2R3N; (R,R2R3R
4N)nXn.

where R8 represents alkyl or alkenyl having about 8 to about 22 carbon atoms, and R2, R3 and R
4 each independently represents hydrogen or alkyl, alkenyl, arylalkyl or alkylaryl having 1 to 22 carbon atoms, and X represents a water-soluble or water-dispersible anion, and n is 1 to 3, preferably is an integer from 1 to 2.

Suitable anions include hydroxyl, chlorine, bromine, sulfate, metasulfate or similar anions.

an alkylene chain having 5 carbon atoms, where the central carbon atoms may be connected to each other by ether oxygens or double or triple bonds.

A common useful diamine is N-alkyltrimethylene diamine (R--C3H, -NH2).

A specific example of a suitable diamine is 2°2'-bis(stearyldimethylammonio) diethyl ether dichloride.

C, 2 to 50 moles of ethylene oxide (typically 2,
5.15 or 50 moles of ethylene oxide)
Salts of ethoxylated amines and diamines with coconut, tallow, soybean and stearyl fatty alkyl groups are also suitable.

D. Salts of alkylimidacillins and imidazoles in which the alkyl group is lauryl, oleyl, stearyl or tall oil are also suitable for the present invention, as long as the system O) is not too alkaline.

Specific examples of these compounds are 1-betahydroxyethyl-2-stearylimidacillin ammonium chloride and 2-stearyl-1,1-methyl[(2-stearylamido)ethyl]imidazolinium methosulfate. be.

E. Still other suitable softeners include alkyl groups of from about 8 to
Included are alkylpyridine and piperidine salts having 22 carbon atoms.

Examples include stearamidomethylpyridinium chloride and stearylpyridinium chloride.

F. Further softening agents include alkylsulfonium salts and alkylphosphonium salts in which the alkyl group has 8 to 22 carbon atoms.

This group of compounds is the fourth compound and will bind to the clay.

An example of this type of salt is.

G, yet other softening agents include esters of amino acids and amino alcohols, where at least one of the two hydrocarbon chains has 8 to 22 carbon atoms and the second The hydrocarbon chain can be alkyl having 1 to 4 carbon atoms or alkyl having 8 to 22 carbon atoms.

H0 Still other softeners include fatty acid ester salts of mono-, di-, and triethanol-amine salts, and alkylguanidine salts in which the alkyl group has 8 to 22 carbon atoms.

Suitable organic fiber softeners will combine with the clay to form a complex containing the compounds that are not in salt form.

However, it has been found more convenient to first convert compounds such as amines into their salt form before combining them with the clay.

The reaction between organic cationic softeners and smectite clay is
Until the cation exchange capacity of clay is approached, the process proceeds mainly by an ion exchange mechanism, and the subsequent mechanism is a type of adsorption.

Once the negatively charged clay particles become increasingly positively charged and adsorption continues, a charge reversal occurs in the organo-clay composite.

The interaction between clay and organic cationic softeners is strong;
This interaction then changes the physical properties of the clay (ie, the viscosity, colloidal stability changes, and the clay becomes hydrophobic).

The composite formed is hydrophobic and difficult to disperse in domestic laundry processes.

Combining the composite with suitable wetting and dispersing agents provides a composition in solid form in which the composite adheres well to fibers when wetted and dispersed in an aqueous medium. It was discovered that

Wetting and dispersing agent The third essential component is the wetting and dispersing agent (
Wetting and dispersing ag
ent).

Wetting and dispersing agents are selected from the group consisting of electrolytes, anionic surfactants and mixtures thereof having a solubility in water of at least 7, preferably at least 10 parts per 100 parts of water at 20°C.

When the electrolyte is present alone, it accounts for about 1% of the composition.
0 to about 90% by weight, preferably about 20 to about 80% by weight,
and most preferably present in an amount of about 30 to about 50% by weight.

When the anionic surfactant is present alone, it is present in an amount of at least about 30% molar equivalents of the organic softener, and from about 50% molar equivalents to about 1 molar equivalent of the organic softener. It is preferred that the anionic surfactant be present in an amount slightly more than a molar equivalent, and most preferably for wetting and dispersing the composite.

If the amount of anionic surfactant is much greater than the molar equivalent of organic softener, it is not detrimental to improving wetting and dispersion, but may be harmful if the composition of the present invention is to be used for rinsing. is not desirable.

When anionic surfactants are used in combination with electrolytes for wetting and dispersion, the anionic surfactants are present in molar equivalents of from about 1 to about 29% to the organic softening agent.

The anionic surfactant is approximately 5% relative to the organic fiber softener.
% to about 25% molar equivalent amount,
Most preferred is a molar equivalent weight of about 10 to about 20%.

Electrolytes As mentioned above, electrolytes having a solubility of at least 7, preferably at least 10 parts per 100 parts of water at 20°C have been found to be suitable wetting and dispersing agents for organo-clay composites. It's being served.

To function as a wetting and dispersing agent, the electrolyte must be present in the composition in an amount from about 10% to about 90% by weight of the composition.

Any amount of electrolyte present in the composition can be used as a filler and processing aid.

The electrolyte may be either crystalline or amorphous in nature.

Furthermore, they may be in either anhydrous or hydrated form.

This is because any form is suitable for the present invention.

The electrolyte facilitates the rapid entry of water into the composition of the invention, the rapid dispersion of the composition into its final particles, and the final particles of the organo-clay composite in the rinse bath. Facilitate rapid dispersion throughout.

When the compositions of the present invention are prepared by agglomerating the clay/organic fiber softening mixture and the electrolyte, the discrete individual particles of the electrolyte prior to agglomeration have an effective diameter of less than about 200 microns.

Preferably it has an effective diameter of about 30 to about 100 microns.

Preferred electrolytes are aluminum sulfate and aluminum chloride, and alkali metal and alkaline earth metal chlorides, sulfates, carbonates, bicarbonates, sesquicarbonates, orthophosphates, pyrophosphates, tripolyphosphates, borates. , silicates, nitrates, acetates, urea and mixtures thereof that meet the solubility tests previously described.

Sodium sesquicarbonate (sodium 5esqui)
carbonate) is a highly preferred electrolyte for use in the present invention.

Other highly preferred electrolytes are water hardness-electrolyte salts (har
dness-electrolyte 5alt),
Especially the Ca and Mg salts.

Particularly preferred are magnesium sulfate, magnesium chloride, and calcium chloride.

These water hardness-electrolyte salts further and unexpectedly increase the fiber conditioning efficacy of the present compositions.

Without wishing to be bound by theory, it is believed that two phenomena are at play that cause water hardness-electrolyte beneficial results on fiber conditioning.

One factor is that the negative charges on the fiber surface and the negative charges present on the surface of the smectite clay platelets are bridged by the water hardness-electrolyte, thereby increasing the transfer of the clay/organic fiber softening mixture to the fiber surface. It appears that the attraction force is increased and therefore the adhesion resistance of the composite is increased.

The second factor is that the water hardness-electrolyte destabilizes the dispersion of the organic softened cutting-clay composite by disrupting the double-layer repulsive forces between the clay platelets, thereby making the composite more easily fibrous. It will adhere to the surface.

Water Hardness - Electrolyte salts are measured when the water used in the rinse bath is soft, i.e., US gallons (3
It will be appreciated that it is particularly beneficial if the hardness is less than about 3 grains per .

Increased fiber conditioning efficacy compared to soft water was observed with the compositions of the present invention when the rinse bath water hardness was 15 grains/US gallon.

Exemplary electrolyte material solubility is as follows, but is not limited to (parts electrolyte per 100 parts water at 20° C.):

54), magnesium sulfate heptahydrate (35), sodium carbonate decahydrate (21), sodium sulfate heptahydrate (19), sodium chloride (101), anhydrous sodium carbonate (15), anhydrous bicarbonate) IJum (9),

and mixtures thereof.

Suitable anionic surfactants are combined with the organo-clay complex, usually in an aqueous medium.

It is believed that the anionic surfactant is adsorbed onto the surface of the composite.

Regardless, anionic surfactants provide the necessary wetting and dispersion of the composite.

In the preparation of the fiber softening detergent compositions of the present invention, the organic-viscosity complex is added to the other components of the detergent composition, named anionic surfactants, rather than as a separate step. Combine the organic-viscous composite with the anionic surfactant in situ.

Optional Ingredients The softener composition need only contain the three essential ingredients.

The composition also contains 2% to about 75%, preferably 5% to 60%
%, most preferably from 10% to 50%, of water-soluble filler.

The fillers include inorganic and organic materials.

Such fillers include sodium carbonate, sodium bicarbonate, sodium sesquicarbonate, urea, sodium sulfate,
Includes sodium borate, magnesium sulfate, sodium chloride, and mixtures thereof.

Manufacture Softener compositions in which the anionic surfactant is a wetting and dispersing agent are manufactured by combining the three essential ingredients in two basic steps.

In the first step, the smectite clay is contacted with an organic softener to form an organo-clay composite.

This step is conveniently carried out in an aqueous system.

Particularly when the organic softener is in salt form, the composite will form at ambient temperature.

If the organic softener is not in salt form and is a solid, the softener must be melted to form the composite before being added to the clay.

In the production of organo-clay composites it is convenient to use temperatures up to about 80°C.

In the second step, the organo-clay composite is contacted with an anionic surfactant.

This step is also conveniently carried out in an aqueous system.

The above order of addition is important for incorporating the anionic surfactant.

It is important that the organic softener be in combination with the clay prior to addition of the anionic surfactant.

Otherwise, the organic softener, especially if it is of the cationic type, is neutralized by the anionic surfactant;
This would result in a decrease in the softening action expected from organic softeners.

Methods for producing the compositions of the invention in granule form are known.

The methods range from those using small amounts of water to those using significant amounts of water.

In particular, one method of manufacturing granular compositions is by agglomeration.

A slurry of organic softener can be sprayed onto the clay particles to form a composite, which step can then be followed by spraying a slurry of anionic surfactant onto the composite.

Devices that can be used for agglomeration include cement mixer, D
ravo pan-type flocculating machine, KG/SchugiBlend
er-Granulator, Rotating Knife Continuous Vertical Fluidized Bed Agglomerator, Niro Fluidized Bed and Obrian Mixer/Agg lom
era, but is not limited to these.

Other processes and equipment that use large quantities of ice include spray drying towers, prilling towers, rotary dryers, and extrusion processes.

In the fabrication process of the softener composition, a convenient time to add optional ingredients such as electrolytes, colorants, fragrances, and fillers is after the organic-clay composite is formed and after the anionic surfactant is added. before and/or after addition.

Optional ingredients can serve as processing aids.

Softener compositions in which the electrolyte is a wetting and dispersing agent are made by combining the three essential ingredients in two basic ways.

In one method, the agglomeration method, the first step in the process is to contact the smectite clay with an organic softener to form the organo-clay composite described above.

In a second step, a binding/matrix agent (e.g. water, electrolyte solution,
The organic-clay composite is coagulated with the electrolyte by spraying with an anionic surfactant (such as an anionic surfactant).

The agglomeration equipment described above can be used in this step.

When using the second method, slurry drying, the first step in preparing the composition is to make a slurry containing the electrolyte in water, add clay, and finally add an organic softener to soften the clay. The method is to combine it with an organic softener.

Anionic surfactant slurry and other optional ingredients can then be conveniently added.

This slurry is then converted to a solid form by driving off excess water, such as by spray drying as described above.

In the process of manufacturing the softener composition, optional ingredients can serve as processing aids.

The particle size of the granules will vary whether produced by agglomeration or slurry-drying methods.

Preferred particle sizes for use in the fabric softener compositions of the present invention in granule form are from about 20 meshes to about 65 meshes (Tyl
er).

Alternatively, for detergent compositions in which the surfactants are primarily or wholly anionic, the organo-clay complex can be added to the component mixture and the complex added during mixing of the components rather than as a separate preliminary step. can be combined with anionic surface activity in situ.
