Title: THICKENING AGENTS FOR ACIDIC AQUEOUS COMPOSITIONS
Abstract:
The use of cross-linked cationic homopolymers as thickening agents for acidic aqueous compositions, for example detergents for toilet cleaning and laundry softeners. The cross-linked cationic homopolymers are homopolymers of cationic monomers of formula (I) cross-linked with a cross-linking agent present in amounts ranging from not less than 50 to about 600 ppm of the homopolymer total weight. Acidic aqueous compositions thickened with said cross-linked cationic homopolymers. The above mentioned cross-linked cationic homopolymers with a cross-linking agent present in amounts ranging from not less than 50 to about 600 ppm of the homopolymer total weight.
