标 题:Nitrogen-containing derivatives of carboxymethylcellulose, their synthesis and their use in cosmetic preparations
发明人：GRUENING BURGHARD; HOFFMANN KLAUS; KOERNER GOETZ; KOLLMEIER HANS-JOACHIM
权利人:GOLDSCHMIDT AG TH
摘要:Derivatives of carboxymethylcellulose are disclosed in which all or a portion of the carboxymethyl groups are replaced by groups of the general formula in which R1 is a hydrogen or methyl group, R2 is a divalent aliphatic hydrocarbon group with 2 to 5 carbon atoms, R3, R4 are alkyl groups with 1 to 4 carbon atoms, R5 is an alkyl group with 1 to 4 carbon atoms or a benzyl group, X is a halogen or sulfate group or a sulfonic acid group, with the proviso that, on the average, at least 0.1 quaternary ammonium groups are contained per anhydroglucose unit of the polymeric molecule. The invention furthermore relates to derivatives of carboxymethylcellulose, in which all or a portion of the carboxymethyl groups are replaced by groups of the general formula in which the substituents R1, R2, R3 and R4 have the above meaning, with the proviso that, on the average, at least 0.1 tertiary amino groups are contained per anhydroglucose unit of the polymeric molecule, as intermediates for the synthesis of the aforementioned derivatives. The invention furthermore is directed to a method for the synthesis of the derivatives of carboxymethylcellulose and their use in cosmetic preparations, especially for the care of hair.

摘要:Betain group-containing derivatives of carboxymethylcellulose are disclosed. They are characterized in that all or a portion of the carboxymethyl groups are or is replaced by groups of the general formula wherein R1 is hydrogen or methyl group, R2 is a divalent aliphatic hydrocarbon group with 2 to 5 carbon atoms, R3, R4 is an alkyl group with 1 to 4 carbon atoms, R5 is a divalent aliphatic hydrocarbon group with 1 to 10 carbon atoms, with the proviso that, on the average, at least 0.1 betaine groups are contained for each anhydroglucose unit of the polymeric molecule. Also, a method for the synthesis of these compounds and their use in cosmetic preparations, especially for the care of hair, are disclosed. In addition, novel derivatives of carboxymethylcellulose with tertiary amino groups are taught as intermediates. In these derivatives, all or a portion of these groups are or is replaced by groups of the general formula in which the substituents R1, R2, R3 and R4 have the above meaning, with the proviso that, on the average, at least 0.1 tertiary amino groups are contained per anhydroglucose unit of the polymeric molecule.
