Description

Description: TECHNICAL FIELD The present invention provides stable, viscous polishing that exhibits excellent cleaning properties, ease of rinsing, and glitter performance and is not aggressive to the surface and packaging material to be cleaned. A polishing composition containing an agent.

These compositions are substantially free of terpene solvent and contain a narrowly defined solvent derived from propylene glycol.

BACKGROUND It is well known to formulate liquid or creamy polishing compositions containing solvents.

In particular, a creamy polishing composition containing an abrasive and a two-component solvent system composed of a terpene and a polar solvent is disclosed in European Patent Application No. 0,126,545. In these compositions, the terpenes exhibit desirable emulsifying properties that enhance cleaning and also product viscosity.

However, it has become desirable to replace terpenes with solvents that are well compatible with all types of surfaces and packaging materials to be cleaned, while at the same time exhibiting good cleaning and emulsifying properties.

It is possible to formulate a terpene solvent-free viscous cream polish cleanser composition containing a narrowly defined solvent derived from propylene glycol and exhibiting outstanding cleaning efficiency, ease of rinsing and surface compatibility,
Found now.

U.S. Pat. No. 3,591,510 discloses the use of solvents of this type in abrasive-free liquid hard surface cleaning compositions. EP-A 0 040 882 describes the use of propylene glycol-derived solvents in combination with terpenes and benzyl alcohol in abrasive-free liquid hard surface cleaners.

It is an object of the present invention to provide a viscous cream cleanser composition that is fully compatible with the surface to be cleaned and the packaging material. Yet another object of the present invention is to provide a cleanser composition having excellent cleaning properties, ease of rinsing, and luster performance.

SUMMARY OF THE INVENTION The present invention is a viscous creamy polish cleanser that is substantially free of terpene solvent and contains a surfactant, an abrasive, an organic solvent, and, if desired, conventional additives.
The cleanser is substantially free of terpene solvent, and the organic solvent is of formula (In the formula, R is a C _{1 to} C ₈ alkyl, alkenyl or alkylaryl group, preferably a C _{1 to} C ₄ alkyl group, and n
Is an integer from 1 to 4, preferably 1 or 2).

DETAILED DESCRIPTION OF THE INVENTION Surfactants, abrasives, solvents and optional ingredients are detailed below.

Unless otherwise specified, the unit "%" means "% by weight".

Surfactants Water-soluble detergent surfactants useful in the present invention include the well known synthetic anionic surfactants, nonionic surfactants, amphoteric surfactants, zwitterionic surfactants and mixtures thereof. Alkyl benzene sulphates, alkyl benzene sulphonates, paraffin sulphonates, olefin sulphonates, alkoxylated (especially ethoxylated) alcohols, alkoxylated (especially ethoxylated) alkylphenols, amine oxides, sulphonates of fatty acids, sulphonates of fatty acid esters, etc., which are well known in the cleaning art,
It represents these surfactants. In general, such detergent surfactants contain an alkyl group of C ₁₀ -C ₁₈ range. Anionic detergent surfactants are most commonly used in the form of their sodium, potassium or triethanolammonium salts. Nonionic surfactants generally contain from 3 to 17 ethylene oxide groups per mole of hydrophobic moiety. C ₁₂ -C ₁₆ alkyl benzene sulfonates, C ₁₂ -C ₁₈ paraffin sulfonates and the formula RO
_{(CH 2 CH 2 O) n} ( wherein, R is C ₁₂ -C ₁₅ alkyl chains, n represents a number from 6 to 10) ethoxylated alcohols are particularly preferred in the compositions of the present invention.

Anionic surfactants are often used in compositions containing 0.3-8.
%, Preferably 2-4%. Nonionic surfactants are used at 0.1-6% by weight of the composition. Mixtures of such surfactants can also be used. The total amount of surfactant is preferably 3% to 5%.

Abrasives The types of abrasives used in the present invention are selected from water insoluble non-coarse grained materials well known in the literature for their relatively mild abrasiveness. It is highly preferred that the abrasives used in this invention are not undesirably "scratch". Abrasive materials having a Mohs hardness of about 7 or less are typically used. Abrasives with a Mohs hardness of 3 or less can be used to avoid scratches on aluminum or stainless steel finishes. As the abrasive suitable for the present invention, an inorganic substance,
In particular, substances such as calcium carbonate and diatomaceous earth, as well as substances such as fuller's earth, magnesium carbonate, china clay, attapulgite, calcium hydroxyapatite, calcium orthophosphate and dolomite are included.
The inorganic material can be qualitized as a "strong abrasive." Urea
Synthetic organic abrasives such as formaldehyde, methyl methacrylate, melamine-formaldehyde resins, polyethylene spheres, polyvinyl chloride, etc. can be advantageously used to avoid scratching on certain surfaces, especially plastic surfaces. When using such "soft abrasives", strong builders can be incorporated into the composition.

Typically, the abrasive has a particle size range of 10-1000μ,
Used in the composition at a concentration of 5% to 30%. Thickeners are often added to suspend the abrasive.

Organic Solvent The organic solvent to be used in the composition has a general formula (In the formula, R is an alkyl, alkenyl, or alkylaryl group having 1 to 8 carbon atoms, and n is an integer of 1 to 4). Preferably, R is an alkyl group having 1 to 4 carbon atoms, and n is 1 or 2. A particularly preferred R group is n-butyl or isobutyl. Most preferred is 1-n-butoxypropan-2-ol (n =
1) 1 (2-n-butoxy-1-methylethoxy) propan-2-ol (n = 2) and mixtures thereof. 1-n-butoxypropan-2-ol is particularly preferred.

The organic solvent of the present invention is used in an amount of 2 to 10% by weight of the composition, preferably 4 to 6% by weight.

The solvent system, optionally, in combination with the above solvent may contain water-soluble carbitol (CARBITOL ^R) solvents or water-soluble cellosolve (CELLOSOLVE ^R) solvent. Water-soluble carbitol solvents are compounds of the 2- (2-alkoxyethoxy) ethanol type in which the alkoxy groups are derived from ethyl, propyl or butyl. A preferred water soluble carbitol is 2- (2-butoxyethoxy) ethanol, also known as butyl carbitol. The water-soluble cellosolve solvent is a compound of the type of 2-alkoxyethoxyethanol, with 2-butoxyethoxyethanol being preferred.

Suitable solvents for use in combination with the solvent of the present invention also include benzyl alcohol and diols such as 2-ethyl-1,3-hexanediol and 2,2,4-trimethyl-1,
It is 3-pentanediol.

The co-solvent may be used in an amount of 0.1-5% of the composition.

The composition is substantially free of terpene solvent. Since the solvent is generally used in an amount greater than about 2%, the terpene
The composition cannot be blended in such a ratio. However, relatively small sub-additive
It is understood that amounts, eg, less than about 0.6% (calculated on the total cleanser composition) of terpenes can be present due to the usual ingredients such as perfumes.

Optional Ingredients In addition to the essential ingredients mentioned above, the composition may contain additional ingredients which may be highly desirable.

For example, it is highly preferred that the composition contains a detersive builder and / or a sequestrant. Compounds that can be classified as detersive builders and are well known in the art include nitrilotriacetate (NTA), ethylenediaminetetraacetate (EDTA), aminopolyphosphonates (DEQUEST), water soluble phosphates such as triphosphate and sodium orthophosphate and pyroline. Sodium acid salts, silicates, and mixtures thereof. These builders are preferably not used in combination with strong abrasives such as calcium carbonate, but are recommended in combination with soft organic abrasives such as polyvinyl chloride.

Sequestering agents with lower sequestration constants
Advantageously, it can be used in combination with a strong or soft abrasive. Examples of these sequestering agents include polycarboxylates and citrates. Preferred builders / sequestrants for use in the present invention are NTA, EDTA,
Citrate and mixtures thereof. builder/
The sequestering agent is 1% to 15%, preferably 2% to 7%.
% Will be present.

Moreover, it is highly preferred to incorporate soap into the compositions of the present invention. Soap produced from coconut oil fatty acids is preferred.

Soaps are used in an amount of 0.2 to 3% by weight of the composition, preferably in excess of 1% by weight, typically 1-2%.

It was surprisingly found that the presence of these large amounts of soap not only provides antifoaming, but also has a thickening effect on compositions containing certain organic solvents of the present invention, so this amount is , Significantly higher than the amounts currently used in similar compositions. This finding makes it possible to keep the amount of thickener at very low levels, thus substantially reducing certain deficiencies of the thickener, eg rinsing difficulties resulting from the use of substantial amounts.

Thickeners should preferably be incorporated into the compositions of the present invention to suspend the abrasive. However, the amount will be kept below 2%, preferably between 0.2% and 1.5%. Conventional thickeners such as polyacrylates, xanthan gum, carboxymethyl cellulose, swellable smectite clays can be used in the present invention.

Also, any compound is represented by ingredients typically used in the trade to provide aesthetics or additional product performance benefits. Typical ingredients include pH modifiers, fragrances, optical brighteners, stain settling agents, detergent enzymes, gel control agents, freeze / thaw stabilizers, bactericides, preservatives and the like.

Another optional ingredient used in the present invention is represented by conventional detergent hydrotropes. Examples of suitable hydrotropes include urea, monoethanolamine, diethanolamine, triethanolamine and xylenesulfonic acid,
Toluenesulfonic acid, ethylbenzenesulfonic acid and isopropylbenzenesulfonic acid sodium salts, potassium salts, ammonium salts and alkanol ammonium salts. However, it is a particular feature of the present invention that stable formulations can be prepared without the need for this type of hydrotrope material.

The composition typically contains up to about 90% water as a carrier. As an example, the amount of water can vary, for example in the range of 50% to 80%. Water-alcohol (eg ethanol, isopropanol, butanol, etc.) mixtures can also be used. The alkylated polysaccharide can be used to enhance the stability and performance properties of the composition.

The composition is preferably in the alkaline pH range, generally
Formulation is at pH 8-11, preferably about 10-0.8. Caustics such as sodium hydroxide, sodium carbonate and the like can be used to adjust and buffer the pH as desired.
