Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a viscous material that exhibits excellent stability, very good leaning and brightening performance, and is non-aggressive to the surfaces and packaging materials to be cleaned. The present invention relates to an abrasive-containing polishing composition.

These compositions are substantially free of unsaturated terpene solvents, but contain saturated terpene solvents.

Background It is well known to formulate liquid or cream polishing compositions containing solvents.

In particular, cream polishing compositions containing a binary solvent system consisting of an abrasive and an unsaturated terpene and a polar solvent are disclosed in European Patent Application No. 0.126.545.

In these compositions, the terpenes provide cleaning benefits and exhibit desirable emulsifying properties during the preparation process, thus increasing product viscosity.

However, it has become desirable to replace unsaturated terpenes with solvents that are fully compatible with all types of surfaces and packaging materials to be cleaned and at the same time exhibit good leaning and emulsifying properties.

It has now been discovered that the use of saturated terpene solvents as replacements for unsaturated equivalents provides desirable compatibility with packaging materials while maintaining very good lean, glitter performance and product viscosity. .

Additionally, the use of saturated terpene solvents provides improvements in terms of product stability and odor quality.

U.S. Pat. No. 4,576,738 discloses hard surface liquid compositions containing saturated terpenes in combination with an aqueous solvent.

However, the prior art does not disclose or suggest the formulation of viscous abrasive-containing polishing compositions containing saturated terpenes.

It is an object of the present invention to provide a viscous cream cleanser composition that is fully compatible with the surfaces to be cleaned and the packaging materials.

Yet another object of the present invention is to provide a cleanser composition with excellent cleaning and brightening performance.

SUMMARY OF THE INVENTION The present invention is a viscous cream polishing composition containing a surfactant, an abrasive, an organic solvent, and optionally conventional additives, the cleanser being substantially free of unsaturated terpene solvents. The present invention relates to a viscous creamy polishing composition characterized in that it does not contain the above and the organic solvent contains a saturated terpene hydrocarbon.

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

Unless otherwise specified, % expressions mean "% by weight".

Surfactants Water-soluble detergent surfactants useful in the present invention include well-known synthetic anionic surfactants, nonionic surfactants, amphoteric surfactants, zwitterionic surfactants, and mixtures thereof. These include alkylbenzene sulfates, alkylbenzene sulfonates, paraffin sulfonates, olefin sulfonates, alkoxylated (especially ethoxylated) alcohols, alkoxylated (especially ethoxylated) alkylphenols, amine oxides, sulfonates of fatty acids, sulfonates of fatty esters, etc., which are well known in cleaning technology. are representative of surfactants. Generally, such detergent surfactants contain alkyl groups in the C1 (1"18 range). Anionic detergent surfactants are most commonly in the form of their sodium, potassium or triethanolammonium salts. The nonionic surfactants generally contain from 3 to 17 ethylene oxide groups per mole of hydrophobic moiety. Inside, R is C

Examples include substances such as calcium hydroxyapatite, calcium orthophosphate, and dolomite. The above inorganic substance can be characterized as a "strong abrasive". Synthetic organic abrasives such as urea-formaldehyde, methyl methacrylate, melamine-formaldehyde resins, polyethylene spheres, polyvinyl chloride can be advantageously used to avoid scratching on surfaces, especially plastic surfaces. like this"
When using "soft abrasives", strong builders can be incorporated into the composition.

Typically, the abrasive has a particle size range of 10 to 200 microns and is used in the composition at a concentration of 5% to 30%. Thickeners are often added to suspend the abrasive.

Organic Solvents The organic solvents to be used in the present compositions contain saturated terpene hydrocarbons.

Saturated terpenes for use in the present invention include hydrogenated materials corresponding to well-known monoterpenes or sesquiterpenes that can be acyclic or cyclic. Preferred materials for use in the present invention include hydrogenated Hydrogenated monocyclic monoterpenes and bicyclic monoterpenes selected from added terpinenes, terbilunes, limonenes, and pinenes.

A highly preferred material is hydrogenated pinene, also known as pinane or 2,6,6-)limethylbicyclo(3,1,1,)heptane.

The saturated terpene hydrocarbons of the present invention may be 1 to 10 i of the composition.
ij is used in an amount of 1%, preferably 1.5-5% by weight.

The solvent system can optionally contain polar solvents in combination with saturated terpene components to further improve cleaning performance. Examples include polar solvents with low water solubility, such as benzyl alcohol, and diols, such as 2-ethyl-1,3-hexanediol and 2.2.4-trimethyl-1,3-bentanediol, and Solvents with high water solubility include, for example, the water-soluble cARBITOLR solvent or the water-soluble Cellosolve (cBLLO9OLVE R) solvent. The water-soluble Calpitol R solvent is a 2-(2-
(alkoxyethoxy) ethanol type of compound. A preferred water-soluble carpitol is 2-(2-butoxyethoxy)ethanol, also known as butyl carpitol.

The water-soluble Cellosolve R solvent is a 2-alkoxyethoxyethanol class of compounds, with 2-butoxyethoxyethanol being preferred.

Benzyl alcohol is preferred for use in the present invention.

The above polar solvents can be used in amounts of 0.5% to 10%, preferably 0.5% to 5% of the composition. The weight ratio of saturated terpene to polar solvent is from 5:1 to 1=5, preferably 2:1
Therefore, 1=2.

The composition is substantially free of unsaturated terpene solvents. Since solvents are generally used in amounts greater than about 2%, unsaturated terpenes cannot be incorporated in the present compositions in such proportions. However, a relatively small amount of sub-addition (sub-
It is understood that amounts of unsaturated terpenes, such as less than about 0.6% (calculated on the total cleanser composition), can be present from conventional ingredients such as fragrances.
