Abstract
A cosmetic composition for application to the hair to delay the appearance of an oily aspect of the hair contains a water-soluble polymer of the poly-.beta.-alanine type.
Claims7
A non-rinse cosmetic composition for the hair to delay the appearance of an oily aspect of the hair comprising
- (i) a water soluble polymer comprising 50 to 100% of units of the formula --CH.sub.2 --CH.sub.2 --CO--NH-- and from 0 to 50% of units of the formula ##STR7## said water soluble polymer having a molecular weight ranging from 500 to 200,000 and being present in an amount effective to delay the appearance of an oily aspect of the hair, and
- (ii) a polyaspartic derivative having the formula:
- ##STR8## wherein R represents hydrogen or lower alkyl,
- b is a whole number ranging from 2 to 6,
- X represents --NR.sub.I (R.sub.II) or .sup..sym. --NR.sub.I (R.sub.II)(R.sub.III)Z.sup..crclbar. wherein R.sub.I, R.sub.II and R.sub.III each independently represent hydrogen, alkyl having 1-18 carbon atoms or alkenyl having at most 18 carbon atoms and Z.sup..crclbar. represents an anion derived from an organic or mineral acid;
- Y represents oxygen, methylene, --N(R'")-- or --N (R'")(R"")Z.sub.1.sup..crclbar. wherein R'" and R"" each independently represent hydrogen, alkyl having 1-18 carbon atoms or alkenyl having at most 18 carbon atoms and Z.sub.1.sup..crclbar. represents an anion derived from an organic or mineral acid;
- R' represents hydrogen, lower hydroxyalkyl, lower hydroxyalkyloxyalkyl, alkyl having 1-18 carbon atoms or alkenyl having at most 18 carbon atoms;
- R" represents hydrogen, lower hydroxyalkyl or lower alkyl;
- M represents hydrogen, alkali metal, 1/2 alkaline earth metal atom or M.sup.+ represents an ammonium ion derived from an amine having the formula, HN(R)--(CH.sub.2).sub.b --X, ##STR9## or HN(R')--R" wherein R, b, X, Y, R' and R" have the meanings given above,
- D represents ##STR10## or --O.sup..crclbar. M.sup..sym. wherein R, b, X, Y, R', R" and M have the meanings given above,
- m, p, q and r each represent a whole number including zero, such that the sum (m+p+q+r) ranges from 15 to 500, m and p being able to be zero simultaneously only when (a) q is other than zero and R' represents hydroxyalkyl and (b) q is equal to zero in an aqueous carrier.
