Abstract:
A body cleansing composition providing upon a single application to a person in need of protection against sunburn protection measured by Sun Protection Factor (SPF) of at least 15 as applied and SPF of at least at least 4 after rinsing, consisting essentially of water, the amount of water being in the range from 30 to 90 parts by weight; at least one first sunscreen compound which is a paramethoxycinnamate ester, and at least one second sunscreen compound able to absorb at least 50% of incident radiation at wave lengths from 290 to 320 nanometers and selected from the group consisting of a 2-hydroxy-4-alkoxybenzophenone, a salicylic acid ester, octocrylene, zinc oxide and mixtures thereof, in which the combined amounts of first sunscreen compound and second sunscreen compound are in the range from 3 to 40 parts by weight; a combination of at least two surface active agents including a first anionic agent which is an alkyl sulfate salt or an alkoxylated alkyl sulfate salt, and a second agent which is nonionic, anionic or zwitterionic, provided that when said second agent is anionic it is not identical with said first anionic agent, the amount of first anionic agent being in the range from 3 to 15 parts by weight and the amount of second surface active agent being in the range from 1 to 10 parts by weight; at least one hydroxyethylated organic nitrogen compound fixative to enhance retention of SPF on the user's skin selected from the group consisting of N-(2-hydroxyethyl)lactamide and a polymeric quaternary ammonium salt having a plurality of quaternary ammonium groups and at least one 2-hydroxyethyl group, the amount of N-(2-hydroxyethyl)lactamide being in the range from 0 to 12 parts by weight and the amount of polymeric 2-hydroxyethyl quaternary ammonium salt being in the range from 0 to 1 part by weight, provided that said amounts are not simultaneously 0; and at least one additive selected from the group consisting of non-aggressive volatile organic liquids boiling within the range of 15 to 60.degree. C., water-immiscible non-volatile organic carriers, and preservatives able to retard microbial spoilage, the amount of non-aggressive volatile organic liquid being in the range from 0 to 12 parts by weight, the amount of water-immiscible non-volatile organic liquid being in the range from 0 to 25 parts by weight, and the amount of preservative being in the range from 0 to 2 parts by weight, provided that the amounts of each such additive are not simultaneously 0; whereby protection against sunburn is imparted to a person in need thereof in a single application of said composition.
