Liquid sunscreen compositions which both deposit and lather well

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 (especi...

Zusammenfassung: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.
