Abstract
Water-proof sunscreen compositions, including a cellulosic polymer, a solvent, an ultra-violet sunscreening agent and an emollient are disclosed. The compositions when spread on the skin leave an elegant non-greasy, non-tacky film with a superior resistance to removal by water and which provide prolonged high level protection for human skin to ultraviolet radiation.
