(57) Abstract : A hair-treating composition containing a diester or polyester of a naphthalene dicarboxylic acid having compound formula (l). (ID, (lII) or mixtures; for imparting gloss and/or hair color stabilization, wherein each R same or different, is an alkyl 3 2 group having 1 to O , 2 carbon atoms, a dio] having the structure HO-RLOH, or a polyglycol haSag the structure HO-R -(-O-R -)m-OH, wherein R and R same or different, are each an alkylene group, straight chain or branched, having 1 to 6 earbon atoms, and wherein m and n are each I to about 100, or a mixture thereof. There dieters and polyesters of formula (I) or (l 0 are quite effective in stabilizing the dibenzoylmethane derivative UV-A tilter compounds making them more effective, and elective for longer periods of time. ABSTRACT A hair-treating composition containing a diester or polyester of a naphthalene dicarboxylic acid having compound formula (I), (II), (IlI) or mixtures; for imparting gloss and/or hair color stabilization : R z -- OH fl) R I @0 -- CO 2 R I (Ill) wherein each R 1, same or different, is an alkyl group having I to 22 carbon atoms, a diol having the structure HO-RE-OH, or a polyglycol having the structure HO-Re-(-O-R2-)m-OH, wherein R z and R 3, same or different, are each an alkylene group, straight chain or branched, having 1 to 6 carbon atoms, and wherein m and n are each 1 to about 100, or a mixture thereof. These diesters and polyesters of formula (I) or (II) are quite effective in stabilizing the dibenzoylmethane derivative UV-A filter compounds making them more effective, and effective for longer periods of time.
