Abstract
A base materials for cosmetics which comprises a silylated peptide of the formula (I): ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are the same or different and each is methyl group or hydroxyl group, R.sup.4 is a group bonding the terminal amino group in a side chain of a basic amino acid to the .alpha.-carbon atom wherein the side chain --R.sup.4 NH.sub.2 may partly form an N-heterocyclic ring, R.sup.5 is a side chain of an amino acid other than the above basic amino acid, A is methylene, propylene, --CH.sub.2 OCH.sub.2 CH(OH)CH.sub.2 -- or --(CH.sub.2).sub.3 OCH.sub.2 CH(OH)CH.sub.2 -- group, m is 0 to 100, n is 0 to 100, and m+n is 1 to 100, provided that m and n only show the number of amino acid units, but not amino acid sequence. The silylated peptide (I) is very useful as an additive for hair and skin cosmetics, particularly for aqueous cosmetics, and have excellent pH and storage stabilities and excellent properties such as gloss and moisture impartment to hairs and skins, improvement of combability of hairs, prevention of hairs from being damaged, restoration of damaged hairs, smoothing skin, and the like.
