| abstract |
A compound is disclosed, having the structure of carboxymethylcellulose in which at least one carboxymethyl group is replaced by a group of the general formula (I):n n<IMAGE>n wherein R<1> is hydrogen or a methyl group, R<2> is a straight chain or branched divalent aliphatic C2-C5 hydrocarbon group, R<3> and R<5> are each, independently, a straight chain or branched C1-C4 alkyl group, R<5> is a straight chain or branched C1-C4 alkyl group or a benzyl group and X is a halogen atom, a sulphate ester group or a sulphonic acid group, with the proviso that at least 0.1 groups of formula (I) are present on average per anhydroglucose unit of the compound's structure. n<??>These compounds are prepared by a process which involves, as intermediate, a derivative of carboxymethyl-cellulose in which at least one carboxymethyl group is replaced by a group of the general formula (II):n n<IMAGE>n n<??>The compounds are used in cosmetic compositions for application to the hair and in the production of paper and textiles. |
