  • Patent number: 5831080
    Abstract: The present invention relates to organosilicon compounds containing glycoside radicals, having units of the formula ##STR1## in which R is identical or different and represents a hydrogen atom or an organic radical,a is 0, 1, 2 or 3,b is 0, 1, 2 or 3 andR.sup.1 can be identical or different and represents a radical of the formulaZ--(R.sup.2 O).sub.c --R.sup.3 -- (II)in whichZ represents a glycoside radical which is built up from 1 to 10 monosaccharide units,R.sup.2 can be identical or different and represents an alkylene radical,c is 0 or a number from 1 to 20, andR.sup.3 represents an alkylene radical, with the proviso that the sum of a and b is less than or equal to 3 and the organosilicon compound comprising units of the formula (I) contains at least one radical R.sup.1 per molecule.
