PHOTOPROTECTING FORMULATIONS

摘要

Topically applicable cosmetic/dermatological compositions well suited for both effective and SPF-enhanced UV-photoprotection of human skin, hair and/or scalp, most preferably packaged as spray delivery systems, contain (a) an effective UV-photoprotecting amount of at least one UV-A and/or UV-B sunscreen, most notably the sunscreen avobenzone, and (b) an amount of the copolymer tricontanyl PVP effective to statistically significantly enhance the SPF value of said at least one UV-A and/or UV-B or avobenzone sunscreen, formulated into (c) a topically applicable, cosmetically/dermatologically acceptable vehicle, diluent or carrier therefor; the subject compositions optionally contain a thus-effective amount of an artificial/sunless tanning agent.
