Abstract
A method of enhancing deposition of benefit agent from bars which method comprises separately preparing an adjuvant composition comprising benefit agent and deposition polymer (e.g., cationic polymer); and base bar composition comprising a surfactant system, wherein the adjuvant composition is initially prepared by mixing components forming the adjuvant composition and water to form a uniform aqueous mixture containing benefit agents having particle size of 0.1 .mu.m to 100 .mu.m and drying said aqueous mixture to form a dried adjuvant composition. By combining adjuvant compositions separately from the base bar composition, it is possible to create a final bar having enhanced deposition of benefit agent without compromising processing or consumer attributes (e.g., foaming).
