Abstract
A composition for topical application to the skin contains, as a fatty product to provide a nongreasy protective and emollient film thereon, a polyether oligomer having the formula ##STR1## wherein R is alkyl having 1-12 carbon atoms; R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or alkyl having 1-6 carbon atoms, with at least two of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 being hydrogen; m is 1-4; n has an average value equal to or greater than 2; and the number of carbon atoms in each repetitive unit being at least 4.
Claims7
A cosmetic method for producing on the skin a matte film which is not greasy and for imparting a protective and emollient effect on the skin which comprises topically applying to the skin an effective amount of a cosmetic composition containing a fatty product, said fatty product being a polyether oligomer, having the formula ##STR6## wherein R represents linear or branched alkyl having 1-12 carbon atoms,
- R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each independently represent hydrogen or alkyl having 1-6 carbon atoms, wherein at least two of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen,
- m is 1-4 and
- n has an average value equal to or greater than 2, the number of carbon atoms in each repetitive unit being at least equal to 4,
- said polyether oligomer having a molecular weight ranging from 200 to 5,000.
