Abstract
Abstract A composition for treating hair containing a cosmetically effective amount of a polycondensable compound having the formula: IN WHICH: Y is selected from the group consisting of H, hydrocarbon chains comprising one to 30 carbon atoms, groups consisting of cosmetic constituents which have -S-S, -SH, -COOH, basic quaternary ammonium, and fatty chain groups, X is selected from the group consisting of O, S and NH, R1 and R2 are selected from the group consisting of lower alkyl and together may form a heterocyclic group, comprising nitrogen and/or oxygen atoms, R3 is selected from the group consisting of H, alkyl, and the two R3 groups may form a heterocyclic group, comprising nitrogen and/or oxygen atoms.
