Abstract:
An aqueous composition comprising:(a) 40-95% by weight aqueous solution having a viscosity greater than 300 centipoises; and(b) 5% to 60% by wt. of a hydrogel composition comprising:(i) 0.1 to 30% by wt. hydrogel composition of at least one polymer soluble in water which polymer is insolubilized when placed in the aqueous solution of item (a);(ii) 0.2 to 30% by wt. hydrogel composition of a polymer soluble in water, and soluble or dispersible in the aqueous solution of item (a); and(iii) 1.0 to 60% water insoluble benefit agent entrapped in a network formed by (i) and (ii);wherein said particles of said benefit agent (iii) have particle size of 0.2 to 200 micrometers;wherein said hydrogel is greater than 25 micrometers;and wherein the size of the hydrogel (b) is greater than that of the benefit agent.
