"WATER COMPOSITION AND PROCESS TO INCREASE THE THICKENING EFFICIENCY OF WATER COMPOSITIONS". Aqueous compositions comprising two or more surfactants and an associative thickener, where the type and amounts of surfactants are selected to provide an aqueous solution having increased thickening properties, are disclosed. In particular, selected surfactant mixtures combined with certain hydrophobically modified polyetherurethane thickeners provide increased thickening properties that are not available when individual surfactants are combined with a thickener. Process for improving the thickening properties of aqueous solutions using the mixed associative / surfactant thickener is also disclosed. The inventive mixed associative / surfactant thickeners are useful as thickening agents in a variety of formulations such as paints, coatings, cosmetics, personal care items and cleaners. |
