Abstract
Cosmetic compositions for the hair and skin are described which are characterized in that they contain a polymer which comprises recurring units having the general formula: ##STR1## in which: k is 0 or 1, and l=1 if k=0, or l=0 if k=1, p=0 or 1 and the radicals R.sub.1 to R.sub.5 represent various specified organic radicals.
