  • Patent number: 6399045
    Abstract: The present invention teaches liquid sunscreen compositions in which level of surfactant is higher than level at which the sunscreen component(s) are still soluble in the surfactant in which they are used; and which comprise minimal levels of cationic polymer. Combination of cationic polymer (especially preferred surfactants and at minimum levels) and minimal levels of sunscreen lead to compositions with minimal levels of deposition and minimal SPF. Further, the compositions also maintain good lather.

  • Patent number: 5858939
    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).
