Abstract
Novel amide derivatives have the following structure (1): ##STR1## where Y is hydrogen or an unsaturated fatty acid residue, A is an hydroxyalkyl group, B is a sugar or phosphate residue, and (C.sub.a H.sub.b) is a hydrocarbon residue with from 7 to 49 carbon atoms. The amide derivative can be employed in compositions, together with a suitable carrier, for topical application, particularly to improve damaged human skin or hair.
Claims7
An amide derivative having the structure (1):
- ##STR12## where Y is H or a residue of an all cis n-6,9 fatty acid or a derivative thereof, having the structure (2):
- ##STR13## where Z is --OH or an epoxy oxygen x is an integer of from 16 to 20
- y is an integer of from 24 to 36, and
- z is 0, or an integer of from 1 to 4;
- provided that:
- when z=0
- then y is an integer from 26 to 36 or when z is an integer of from 1 to 4, then y is an integer of from 24 to 35;
- and where
- a is an integer of from 7 to 49
- b is an integer of from I0 to 98
- and where A is the group
- --(CH.sub.2).sub.c OH, where c is an integer of from 1 to 6 or ##STR14## where X.sup.1, X.sup.2, and X.sup.3 are individually H, C.sub.1-5 alkyl or hydroxyalkyl, and R.sup.1 is H, a sugar residue or a phosphate residue,
- and where B is ##STR15## where R.sup.2 is H, a sugar residue or phosphate residue;
- and
- R.sup.3 is a C.sub.8-28 aliphatic hydrocarbon or the group --CH(OH) R.sup.3 with R.sup.3 as defined above;
- and
- wherein at least one of R.sup.1 and R.sup.2 must be a phosphate residue.
