Description

  The present invention relates to a liquid cleaning composition suitable for cleaning kitchen utensils, cooking utensils, etc., and furthermore, generation of chlorine gas can be suppressed even when mixed with a chlorine bleach or a chlorine bleach-containing detergent. Further, the present invention relates to a liquid detergent composition for kitchen that exhibits high detergency.

2. Description of the Related Art Conventionally, liquid detergents such as kitchen detergents and residential detergents have been required to have basic performances such as detergency and foamability.
In recent years, liquid detergents have become more compact, the safety of detergents has become more important, and plastic containers such as tapper containers that are hard to remove dirt have increased in the kitchen. There is a need for a liquid cleaning agent that can remove such dirt.
So far, it has been known that an anionic surfactant and a polyvalent metal ion such as magnesium are used together to exhibit excellent cleaning performance such as foaming and oil stain cleaning properties (Patent Documents 1 and 2). .

On the other hand, in homes, bleaching for clothing, kitchen bleach, mold remover, toilet cleaner, and drainpipe cleaning containing hypochlorite such as sodium hypochlorite because of its excellent bleaching power Many so-called chlorinated bleaches and chlorinated bleach-containing detergents such as detergents and disinfectants are used, and liquid detergent compositions containing the above polyvalent metal ions are chlorinated. There is a safety problem that chlorine gas is generated when it comes in contact with bleach or chlorine-based bleach-containing detergents.
Many liquid detergent compositions containing an anionic surfactant and magnesium ions have been known so far. For example, an anionic surfactant containing an enzyme and a liquid detergent composition containing magnesium ions (see, for example, Patent Document 3) In addition, a liquid detergent composition containing a specific metal ion by the present applicant (Patent Document 2) is known.

  According to the present invention, generation of chlorine gas can be suppressed even when contacted with a chlorine bleach or a chlorine bleach-containing detergent, and a high detergency against dirt on a plastic container such as a tapper container, particularly oily dirt. The liquid detergent composition for kitchens which exhibits can be provided.

Component (A) The component (A) that can be used in the present invention is an anionic surfactant, and is roughly classified into a carboxylate type, a sulfonate type, a sulfate ester type, and a phosphate ester type. It is done. Among these, a sulfonate type and a sulfate ester type are preferable. Examples of the sulfonate type include alkylbenzene sulfonate, alkane sulfonate, α-sulfo fatty acid derivative, α-olefin sulfonate, α-sulfo fatty acid alkyl ester salt and the like. From the viewpoints of detergency and storage stability of the composition, alkane sulfonate is preferred.

Examples of the sulfate salt type include alkyl or alkenyl sulfate salts, polyoxyethylene alkyl or alkenyl sulfate salts, and the like. From the viewpoints of detergency and storage stability of the composition, polyoxyethylene alkyl sulfate salts are preferred.
The polyoxyethylene alkyl ether sulfate ester salt is represented by the following general formula (2).

^{_{R 1 O- (CH 2 CH 2}} O) n 1 -SO 3 M ··· (2)

In the general formula (2), R ¹ is a linear or branched alkyl having 8 to 18 carbon atoms, preferably 10 to 16 carbon atoms, more preferably 12 to 13 carbon atoms. If R ¹ is less than 8, sufficient detergency cannot be obtained because of insufficient hydrophobicity. Further, kitchen liquid detergent composition of the present invention, although the components are prepared by dissolving in water, if R ¹ is greater than 18, the water of the surfactant per se of the formula (2) This is not preferable because the solubility in the aqueous solution decreases and precipitation tends to occur during storage.
n ₁ is the average number of added moles of ethylene oxide groups, and is 1 to 6 mol, preferably 1 to 4 mol, more preferably 1 to 3 mol from the viewpoint of detergency against oil stains.
M is a hydrogen atom, an alkali metal such as sodium or potassium, an alkaline earth metal such as calcium or magnesium, an alkanolamine such as triethanolamine, or ammonium. Among these, an alkali metal is preferable and sodium is more preferable.

R ¹ is a linear or branched alkyl group and is not particularly limited. The structure of R ¹ is determined by the higher alcohol as a raw material. The higher alcohol is usually selected from the following industrially easily available.
(A) Product name Neodol 23 (branch rate: 20%) manufactured by Shell Chemicals. This is produced from an n-olefin by a modified oxo method and rectified.
(B) C13 alcohol obtained from butene trimer by oxo method (branching rate: 100%)
(C) Higher alcohol (branch rate 100%) obtained from a medium chain alcohol by garvet reaction
(D) Product name Safol 23 (branch rate 50%), manufactured by Sasol. In this method, an olefin obtained from gasification of coal is obtained by obtaining an alcohol by the oxo method and further hydrogenating it.
(E) Natural higher alcohols synthesized from natural fats and oils (branching rate: 0%)

  Here, “branch ratio” and “intermediate chain branch ratio” will be described by taking, as an example, a primary higher alcohol which is a raw material of the polyoxyethylene alkyl ether sulfate salt represented by the formula (2). The higher alcohol is, for example, a mixture of a branched higher alcohol represented by the following formulas (III) to (IV) and a linear higher alcohol represented by the formula (V).

In the formulas (III) to (V), R21, R23, and R31 are linear alkyl groups having 1 or more carbon atoms, R32 and R22 are alkyls having 2 or more carbon atoms, p is 1, q is 2 to 3, r is an integer of 1 or more, and the total number of carbon atoms in each formula is equal to the carbon number of R ¹ in formula (I2).
“Branching rate” is the mass of the branched alkyl group in the compounds represented by the above formulas (III) to (IV) relative to the total mass of the hydrocarbon moiety in the compounds represented by the above formulas (III) to (V). Represents a percentage.
“Intermediate chain branching ratio” represents the ratio of the mass of the compound represented by the above formula (IV) to the total mass of the hydrocarbon moiety in the compounds represented by the above formulas (III) to (IV).

The branching rate and the intermediate chain branching rate can be measured under the following conditions using GC / MS.
<Measurement conditions for GC / MS>
Column: Ultra Alloy PY-1
Temperature: Oven; Temperature rising rate 10 ° C / min 50 → 310 ° C
Inlet; 310 ° C
Detector: 310 ° C
Carrier gas: He
Table 1 shows the results of measuring the branching rate and the intermediate chain branching rate using Sasol 23 of Sasol.

Furthermore, the distribution of the number of moles of ethylene oxide added in the polyoxyethylene chain of the general formula (2) varies depending on the catalyst used for the addition reaction of ethylene oxide. With sodium hydroxide or potassium hydroxide, which are common catalysts, the distribution of the number of moles of ethylene oxide added is wide.
On the other hand, when the composite metal oxide Lewis acid sintered solid catalyst composed of Al / Mg / Mn described in Example 1 of Japanese Patent No. 3312883 is used, a polyoxyethylene alkyl having a narrow distribution of ethylene oxide addition mole number is narrow. Ether is obtained.
When these are sulfonated or sulfated with sulfane, polyoxyethylene alkyl ether sulfates are obtained, but the raw materials with a narrow distribution of the number of added moles of ethylene oxide as a raw material, specifically the narrow rate defined by the following formula: Is preferably 55% or more from the viewpoint of low temperature stability and detergency of the composition.
Narrow ratio = Y _max-2 + Y _max-1 + Y _max + Y _{max + 1} + Y _{max + 2}
(here,
Y _i indicating the proportion of the ester salt of the formula (2) in which the number of moles of ethylene oxide added is i,
Based on the total amount of polyoxyethylene alkyl ether sulfate ester salt represented by formula (2), the maximum value Y _i takes is Y _max ,
The value of the number of moles of ethylene oxide added when Y _i takes Y _max is n _max ,
n is the value of Y _i when an (n _max -2) and Y _max-2,
The value of Y _i when n is (n _max −1) is Y _max−1 ,
The value of Y _i when n is (n _max +1) is Y _{max + 1} ,
The value of Y _i when n is (n _max +2) is Y _{max + 2} .
However, when n _max−2 , n _max−1 or n _max is zero, Y _max−2 , Y _max−1 or Y _max is not counted. )

  When the polyoxyethylene alkyl ether sulfate salt (A) is used alone or in combination with other anionic surfactants, the content of the sulfate ester is 5 to 35% by mass (hereinafter simply referred to as “component”). In the case of “%”, it means “mass%”.) It is preferably contained, more preferably 5 to 30%. If it is less than 5%, it may be inferior in low-temperature stability, cleaning performance, and foaming power. Even if it exceeds 35%, the cleaning performance is not significantly improved.

Furthermore, in the present invention, a secondary alkanesulfonic acid represented by the general formula (1) and / or a salt thereof can be used as the sulfonic acid type.

Alkane sulfonic acid is also called paraffin sulfonic acid and belongs to anionic surfactants, but is superior to other anionic surfactants in terms of detergency, foaming and hard water resistance. .
Examples of the alkanesulfonic acid and / or salt thereof that can be used in the present invention include 10 to 21 carbon atoms per molecule, preferably at least 80% by mass, and more preferably at least 90% by mass per molecule. Mention may be made of mixtures of secondary alkyl sulfonic acids with ˜18 carbon atoms and small amounts of primary alkyl sulfonic acids, disulfonic acids or polysulfonic acids and / or their salts.
Examples of the salt include alkali metal salts, ammonium salts, and alkanolamine salts such as sodium, potassium, ammonium, and alkanolamine salts.

When the secondary alkanesulfonic acid and / or salt thereof is used alone or in combination with another anionic surfactant as the component (A), the content of the sulfonic acid and / or salt thereof is 1 to It is 10% by mass, preferably 1 to 8% by mass, more preferably 2 to 6% by mass. If the amount of secondary alkanesulfonic acid and / or salt thereof is in such a range, it is preferable because the high detergency against dirt such as a tapper container, which is the effect of the present invention, can be exhibited. Then, the foam quality deteriorates due to the decrease in foam film stability.
As the component (A), a polyoxyethylene alkyl ether sulfate ester salt and / or an alkanesulfonic acid represented by the formula (1) and / or a salt thereof are preferable.
It is particularly preferable to use the polyoxyethylene alkyl ether sulfate ester salt represented by the above formula (2) in combination with the alkanesulfonic acid represented by the formula (1) and / or a salt thereof. In this case, the sulfate ester salt represented by the formula (2) and the alkanesulfonic acid represented by the formula (1) and / or a salt thereof are preferably 4/3 to 8/1 in terms of mass ratio. .

(B) component (B) component is an amine oxide type surfactant which is a semipolar surfactant. The amine oxide type surfactant is usually represented by the formula R (R ′) ₂ NO.
In the amine oxide type surfactant as the component (B), the group R representing an alkyl group, an alkanoyl group or the like may be linear or branched. The carbon number is preferably 8 to 16 and more preferably 10 to 14 from the viewpoint of detergency. R ′ is a linear or branched alkyl group, and the carbon number thereof is preferably 1 to 3, more preferably 1 to 2.
Specific examples include alkyl dimethyl amine oxide, alkanoyl amide alkyl dimethyl amine oxide, alkyl diethyl amine oxide, and the like. Among these, alkyl (C8-16) dimethylamine oxide is preferable, and alkyl (C10-14) dimethylamine oxide is more preferable. As the component (B), one amine oxide type surfactant may be used alone, or two or more kinds may be mixed and used.

  (B) It is preferable that content of a component is 1-10 mass% in a composition, Preferably it is 1-8 mass%, More preferably, it is 2-6 mass%. When the content of the component (B) is less than 1% by mass, an improvement in cleaning performance due to a synergistic effect with the component (A) is not expected. On the other hand, when it exceeds 10% by mass, the viscosity is increased and the fluidity tends to be lost. In addition, since the component (B) undergoes a charge change depending on the pH and the interaction with the component (A) may change, it is preferable to adjust the pH in the composition of the present invention, which is preferable for the composition. The pH is 5.5 to 7.5 at 25 ° C., more preferably 6.0 to 7.0. When the pH is less than 5.5, the interaction between the component (A) and the component (B) is too strong and tends to cause gelation or solidification. In some cases, the action becomes too weak, and the effect of improving the cleaning performance is reduced.

Component (C) The magnesium compound used as the component (C) of the present invention is one kind as a hydroxide, chloride, acetate, formate, oxide, carbonate or sulfate, nitrate, or a hydrate thereof. Two or more kinds are mixed and used in the composition. Of these, hydroxides and sulfate hydrates are preferred.
The content of component (C), particularly sulfate hydrate, is 0.1 to 10% by weight, preferably 0.5 to 8% by weight, more preferably 1 to 5% by weight, based on the total amount of the composition. It is desirable to be present in an amount.
When the content of the component (C) is expressed in terms of magnesium ion concentration, it can be calculated from the following formula from the magnesium atomic weight 24.3 and the molecular weight of various magnesium compounds.
Magnesium ion content (mass%) =
Magnesium compound content (mass%) × 24.3 / magnesium compound molecular weight When converted to magnesium ion concentration, the content of component (C) is 0.01 to 1 mass%, preferably 0, based on the total amount of the composition. It is desirable to be present in an amount of 0.03 to 0.8 mass%, more preferably 0.05 to 0.6 mass%.

(D) component (D) component of this invention is sulfamic acid.
The content of the component (D) is preferably 0.01 to 5% by mass, more preferably 0.01 to 1% by mass, and 0.05 to 3% by mass with respect to the total amount of the composition. It is more preferable that it is 0.05 to 2% by mass.

In the present invention, the combined use of the component (C) and the component (D) suppresses the generation of high detergency and chlorine gas generated when mixed with a chlorine bleach or a chlorine bleach-containing detergent. It becomes possible.
Further, there is an optimum range for the mass ratio of the (C) component and the (D) component, and the mass ratio of the (C) component / (D) component is in the range of 1/20 to 2/1, preferably 1 / 20 to 3/2, more preferably 1/15 to 1/1. When the mass ratio is larger than 2/1, the chlorine gas generation suppressing effect of the present invention cannot be expected. On the other hand, even when blended at less than 1/20, that is, when the component (D) is used in an amount of 20 times or more of the component (C), the chlorine gas suppressing effect is hardly increased.

It is possible to mix | blend various arbitrary components with the liquid cleaning composition for kitchens of this invention according to the objective and use in the range which does not impair the effect of this application.

In addition, amphoteric or amphoteric surfactants such as alkyl acetate betaines, alkanolamidopropyl acetate betaines, alkyl imidazolines, and alkylalanines, and cationic surfactants such as alkyl trimethyl ammonium salts, dialkyl dimethyl ammonium salts, and alkyl pyridinium salts. .

  Moreover, an aromatic sulfonate is mentioned as a hydrotrope. Aromatic carboxylic acids such as benzoates, ethanol, various perfume-modified ethanol, water-soluble solvents such as isopropanol and butyl carbitol, hydroxycarboxylic acids such as glycolic acid, lactic acid, malic acid, citric acid, tartaric acid and gluconic acid Polycarboxylic acids such as oxalic acid, malonic acid, succinic acid, fumaric acid, aminocarboxylic acids such as ethylenediaminetetraacetic acid, nitriloacetic acid, hydroxyethylethylenediaminetriacetic acid, diethylenetriaminepentaacetic acid, triethylenetetraminehexaacetic acid, polyacrylic acid , Polymaleic acid, polyacrylic acid / polymaleic acid copolymer type carboxylic acid type vaporizer, inorganic builder such as sodium sulfate and magnesium sulfate, viscosity modifier, colorant, antioxidant, preservative, Disinfectant, disinfectant, anti-inflammatory agent, medicinal ingredients, fragrance, natural extraction Usually the components used, such as ones can also be suitably formulated.

The viscosity of the composition of the present invention at 25 ° C. is preferably 50 to 500 (mPa · s). Preferably it is 50-300, More preferably, 80-200 is good. When it is less than 50, a problem of dripping may occur, and when it is more than 500, dischargeability from the container may deteriorate. As the viscosity modifier, a solvent, an organic salt, an inorganic salt, or a polymer having a hydrotrope effect for improving low-temperature stability is preferable. The viscosity of the composition of the present invention was filled with 90 g of the composition of the present invention in a PS11 bottle, adjusted to 25 ° C. in a 25 ° C. constant temperature bath, and No. in the Bismetron VDA viscometer manufactured by Shibaura System Co., Ltd. . This can be determined by installing a 2-rotor, setting a constant temperature sample solution, first setting the rotational speed of the rotor to 60 rpm, and measuring the viscosity after 20 seconds.
The composition of the present invention can be produced by adding the components (A) to (D) and, if necessary, optional components to water and mixing them.
