Abstract
Clear, water-proof sunscreen compositions, including a film-forming resin, a solvent, an ultra-violet sunscreening agent and emollients 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.
