Emulsifying composition, useful in water-resistant make-up or anti-sun compositions, comprises free and phosphated arachidyl and/or behenyl alcohol and alkyl polyglycoside

摘要

An emulsifying composition (A) comprises (by weight): (a) 10-90% arachidyl and/or behenyl alcohol; (b) 90-10% phosphate ester of arachidyl and/or behenyl alcohol; and (c) up to 20% alkyl polyglycoside(s) (I). An emulsifying composition (A) comprises (by weight): (a) 0-90 (preferably 15-90, especially 30-70)% arachidyl and/or behenyl alcohol; (b) 90-10 (preferably 85-10, especially 70-30)% phosphate ester of arachidyl and/or behenyl alcohol; and (c) up to 20 (preferably 1-20, especially 1-10)% alkyl polyglycoside(s) of formula RO(Y)p (I). R = 14-22C (preferably 20-22C) alkyl; Y = residue of a 5-6C sugar (preferably glucose or xylose); p = 1-5 (preferably 1-2.5, especially 1-2). Independent claims are included for: (1) the preparation of (A), by phosphation of arachidyl and/or behenyl alcohol, followed by reaction of the unreacted alcohol(s) with a 5-6C sugar; and (2) emulsions containing (A).
