ABSTRACT:
Sunscreen compositions are made capable of rapid, uniform and stable diffusion in emulsified form in fibrous sheet applicator and of drying on the skin to non-tacky, non-greasy films, by emulsifying (1) about 1-25 wt. % of a substantially water-insoluble UV absorbing component capable of absorbing in at least the 290-320 nm range, (2) about 5-20 wt. % of a cosmetically acceptable alcohol, (3) about 1-10 wt. % of a nonionic emulsifier component, (4) about 0.01-0.5 wt. % of a hydrophilic acrylic acid polymer having a molecular weight of at least about 4.5.times.10.sup.5, (5) an effective amount of an alkaline neutralizer for the acrylic acid polymer, (6) about 2.5-20 wt. % of an emollient component and (7) at least about 50 wt. % water.
Fibrous sheets impregnated with the compositions can be packaged in vapor-and moisture impermeable containers for stable storage and convenient use.
