ABSTRACT:
Betaine group-containing polysaccharides with recurring anhydroglucose units of the average, general formula ##STR1## are disclosed. In this formula the R.sup.1 groups are the same or different and represent methyl, ##STR2## in which n=2 or 3, m=0 to 10, p=0 to 10 and R.sup.2 is a hydrogen atom or the betaine group ##STR3## in which R.sup.3 and R.sup.4 are the same or different and represent an alkyl group with 1 to 4 carbon atoms and R.sup.5 is a divalent aliphatic hydrocarbon group with 1 to 10 carbon atoms, with the proviso that at least 0.5% of the R.sup.1 groups in the polysaccharide molecule represent the betaine group.
Also disclosed is a method for the synthesis of these compounds and their use in cosmetic preparations, expecially for the care of the hair. In addition, novel compounds of the general formula ##STR4## are disclosed as intermediates in which the substituents R.sup.3, R.sup.4 and R.sup.5 have the above meaning.
