Abstract
A cosmetic composition comprises a cosmetically acceptable vehicle and at least one copolymer having units of a vinyl, allyl or methally ester of an .alpha.- or .beta.-cyclic carboxylic acid. A process for producing the said copolymer comprises reacting the monomeric constituents of the copolymer at a temperature between 45.degree.-100.degree. C. for a period ranging from 6 to 24 hours.
Claims15
A cosmetic composition for treating the hair comprising a cosmetically acceptable vehicle and at least one copolymer having the formula:
- ##STR15## wherein:
- m, n, s and t are 1 or 2,
- R, R' and R" each independently represent hydrogen or methyl,
- Z represents a divalent radical selected from the group consisting of --CH.sub.2 --, --CH.sub.2 --O--CH.sub.2 -- and --CH.sub.2 --O--(CH.sub.2).sub.2 --,
- R.sub.1 represents linear or branched alkyl or alkenyl, having 2-21 carbon atoms,
- when s=1, Cyc represents a saturated or unsaturated mono- or poly-cyclic radical selected from the group consisting of:
- (i) a radical of the formula ##STR16## (ii) a radical of the formula ##STR17## wherein R.sub.2 is hydrogen or methyl and p is 1 or 2, (iii) a radical of the formula ##STR18## and (iv) a radical of the formula ##STR19## wherein R.sub.3 represents hydrogen, methyl, ethyl, tert.-butyl, ethoxy, butoxy or dodecoxy and R.sub.4 represents hydrogen, alkyl having 1-4 carbon atoms or alkoxy having 1-4 carbon atoms,
- when s=2, Cyc represents a radical of the formula ##STR20## wherein R'.sub.3 and R'.sub.4 have the same meanings given for R.sub.3 and R.sub.4, respectively,
- v represents from 10 to 91 weight percent,
- w represents from 3 to 20 weight percent,
- x represents from 4 to 60 weight percent, and
- y represents from 0 to 40 weight percent, with the sum v+w+x+y being equal to 100 weight percent.
