Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention 1] The present invention relates to a polishing cleaning liquid composition containing a granular abrasive that is stably dispersed in an aqueous medium.

Abrasive cleaning fluids have been known for many years.1 Such abrasive cleaning fluids are useful for removing stubborn dirt, oil stains, burnt marks, stains, etc. that are difficult to remove with non-abrasive cleaning fluids. It is widely used in regular households to clean hard-surfaced items.

In the last 20 years, a series of publications have been published on the composition of polishing cleaning fluids. Many of them address the stability and dispersibility of aqueous media. Regarding dispersion media, for example, British Patent No. 1.167 , No. 597, No. 1,181,607, No. 1.262.280, No. 1.303.810, No. 1
．． No. 308.190 and No. 1,418,671. European Patent Nos. 50887 and 80221
et al. disclose the stability of dispersion media at high shear stress.

Polishing cleaning fluids have become increasingly sophisticated in recent years, and usability, in addition to direct cleaning efficiency, has become an important factor compared by consumers. In the industry, cleaning efficiency,
It refers to a polishing cleaning liquid that has the following properties: non-cleft, foaming, creamy feel that does not give off roughness, and ease of rinsing. However, some of these cannot be achieved at the same time.

Cleaning efficiency and non-crack-free feel are not compatible, and lathering and ease of rinsing are also not compatible.

It has been known for a long time that the particle size of the abrasive is extremely important in the performance of a cleaning agent. Until recently, it was not known that it plays an important role in the composition of fluids.

British Special Edition No. 1,581,433 describes the manufacture of cleaning agents;
It has been shown that reducing the finest part of the abrasive powder during cleaning significantly improves rinsing performance.

Particles with a particle size of 10 microns or less are less than 20Φ% -1
$t7 where there are virtually no particles larger than 125 microns
It is said that the degree distribution is good.

U.S. Pat. No. 4,181,633 discloses a polishing cleaning liquid composition containing C meta fTv calcium alone or in combination with calcium carbonate as a polishing cleaning agent with excellent cleaning action and less wear. The average particle size of the abrasive is 5.5-1
It is said that there are virtually no coarse grains in the 6 micron range 'c/lo micron L1'.

U.S. Pat. No. 4,302,347 teaches a multi-purpose ω1 polishing cleaning fluid consisting of a granular water-insoluble abrasive with an F7 diameter of 1 to 20%. ing. This composition is creamy and is said to efficiently remove dirt and grime from oil and fat without causing scratches.

British Patent No. 2,125,428 describes an abrasive cleanser composition comprising an abrasive powder with an average particle size of 4 to 17.5 microns and substantially free of coarse particles greater than 75 microns. There is. It is said to have a soft and smooth feel and sufficient cleaning performance.

Compared to conventional household abrasive cleaning solutions that contain abrasive powder with a particle size of 1 to 150 µm and an average particle size of 10 to 50 µm, recently the particle size has been shifted to a much finer side. It has also been proposed to sharpen the distribution to improve the feel and irritation performance without degrading the cleaning performance.

The problem with polishing cleaning liquid compositions that use a high percentage of fine abrasives, especially ultra-fine particles, is that the fine powder aggregates during storage and becomes much larger, impairing the feel of the product and damaging soft materials such as plastics. It may scratch or scratch the surface, and it may cause it to swell.

[Constitution of the present invention] In view of the above-mentioned problems of the prior art, research has been conducted, and in particular, it has been found that the tendency of particle growth can be suppressed by appropriately selectively covering a phosphorus-free composition with an electrolyte. The present invention is based on this knowledge and has the following configuration.

Mineral abrasive particles in the particle size range of 1 to 10 microns 40~
70% by weight, and one selected from the group consisting of alkali metal or ammonium salts of acid, carbonic acid, TA acid, hydrochloric acid, amber acid, adipic acid, and glutaric acid; or A phosphate-free polishing cleaning liquid composition comprising 20% by weight or less of two or more types of electrolytes and stably dispersed in a liquid medium.

Abrasive materials suitable for use in the present invention are natural or synthetic mineral abrasives. Examples of these are:

The mineral abrasive is 40 to 70% by weight of the composition of the present invention,
It is preferably contained in a proportion of 45 to 55% by weight.

In the present invention, 6J+abrasive is divided into 1 to 1
The particle size is in the range of 0 microns [l]. In this case, the range is wI'fJ to C, meaning that those exceeding 10 microns are less than 10 microns, and those less than 1 micron are less than 30 microns. The fractionation in this l-limit is preferably such that the number of particles larger than 10 μm is less than 5% by weight, ideally less than 3% by weight. As for the lower limit, although it does not overlap with the culm-sharp distribution, good results can be obtained if the fine particles of less than 1 mil are 20% by weight.

The average particle size according to the present invention is in the range of 1 to 5 microns in terms of curvature, and the optimum range is 2 to 4 microns.

Mineral MgrtH abrasives are stably dispersed in liquid media. 1. The liquid medium is usually aqueous and contains an anionic active agent, preferably in coexistence with a nonionic or amphoteric active agent.

It is 0.5-15%, preferably 1-5%.

In many cases, nonionic or amphoteric active agents are added to an aqueous medium at 0.0%.
It is recommended to add 3 to 7%, preferably 0.5 to 5%. Suitable examples of the anionic activator include straight-chain or -6-alkol having 8 to 18 carbon atoms, fatty acid amide or fatty acid amide having 8 to 18 carbon atoms, and fluoramide (both mono and diamide). , a water-soluble condensate of alkylphenol having 9 to 18 carbon atoms, etc., and ethylene oxide and/or zolopyrene oxide. The xylated mono- or di-fatty acid alkylamide having 8 to 18 carbon atoms is

Also suitable as anionic activators are mono- or dialkylolamides in which the fatty acid residue has 10 to 16 carbon atoms, such as mono- or dialkylolamides of oil fatty acids.

As an amphoteric activator, one long-chain alkyl group (3 carbon atoms)
