Description

CLEANING COMPOSITIONS FOR LIQUID BATHROOM FOR ALL PURPOSES Field of the Invention The present invention relates to a cleaning composition for a bathroom for all purposes designed to prevent the accumulation of soap impurities.

Background of the Invention This invention relates to a liquid cleaning composition for all designed and particular purposes for cleaning hard surfaces and which is effective to prevent the accumulation of soap impurities and to leave surfaces without rinsing with a glossy appearance.

In recent years, liquid detergents for all purposes have become widely accepted for cleaning hard surfaces, eg, painted panels and mader, tiled walls, bathroom sinks, tubs, mosaic or linoleum floor, washable wallpaper. , etc. Tale liquids for all purposes include opaque and clear aqueous mixtures of soluble synthetic organic detergents and water and water soluble detergent builder salts. In order to achieve a cleaning efficiency comparable to that of cleaning compositions for all powder or granular purposes, the use of water-soluble inorganic phosphat enhancer salts in liquids was favored for all purposes of the prior art. For example, such first phosphate-containing compositions were described in U.S. Patent Nos. 2,560,839; 3,234,138; and in British Patent No. 1,223,739.

In view of the efforts of environmentalists to reduce phosphate levels in the earth's water, liquids have appeared for all improved purposes that contain reduced concentrations of inorganic phosphate-boosting salts or phosphate-free booster salts. A particularly useful autopacified liquid of the above type is described in U.S. Patent No. 4,244,840.

However, these liquid detergents for all purposes of the prior art containing detergent builder salts or other equivalents tend to leave films, stains or scratches on clean surfaces without rinsing, particularly on glossy surfaces. Therefore, such liquids require a thorough rinsing of clean surfaces which is a time-consuming task for the user.

In order to overcome the above disadvantage of liquids for all purposes of the prior art, U.S. Patent No. 4,017,409 teaches that a mixture of paraffin sulphonate and a reduced concentration of an inorganic phosphate booster should be employed However, such compositions are not completely acceptable from an environmental point of view based on the phosphate content. On the other hand, another alternative to achieve liquids for all phosphate-free purposes has been the use of a larger proportion of a mixture of non-ionic and anionic detergents with small amounts of glycol ether and organic amine solvent as shown in U.S. Patent No. 3,935,130. Again, this approach has not been completely satisfactory and the high levels of organic detergents necessary to achieve cleaning make a foaming which, in turn, leads to the need for a thorough rinsing which has been found to be undesirable. the consumers of today.

Another approach to formulate a liquid detergent composition for all purposes or for hard surfaces and where the clarity and homogeneity of the product are important considerations involves the formulation of oil in water microemulsions (o / w) which contain one or more surfactant detergent compounds, a solvent immiscible in water (typically a hydrocarbon solvent) water and a "cosurfactant" compound which provides stability to the product. By definition, an oil-in-water microemulsion is a colloidal dispersion that is formed spontaneously from "oil" phase particles having a particle size in the range of 25 to 800 A in a continuous aqueous phase.

In view of the extremely fine particle size of the dispersed oil phase particles, the microemulsions are transparent to light and clear they are usually highly stable against a phase d separation.

More particularly, the improved cleaning compositions exhibit good greasy dirt removal properties from the bath due to the improved interfacial tensions, when used in the undiluted (pure) form and leave the surfaces clean bright without the need for only a cleaning or minimal additional rinsing. The above characteristic is evidenced by the few or no visible residues on the cleaned surfaces without rinsing and, therefore, overcomes one of the disadvantages of the products of the previous art. The present compositions prevent or diminish and stick soap impurities on surfaces that have been cleaned with the present compositions as compared to the cleaned surfaces with a commercial microemulsion composition which means that the accumulation of soap impurities is stopped.
