ABSTRACT:
The specification describes and claims certain organosilicon compounds and the preparation thereof. The organosilicon compounds comprise (A) a silane according to the general formula R.sup.1.sub.a A.sub.b Si(R"NXR').sub.c or (B) a polysiloxane comprising one or more siloxane units according to the general formula (i) ##EQU1## any remaining units of the polysiloxane being at least predominantly according to the general formula (ii) ##EQU2## A represents a hydroxyl or a hydrolyzable group, R.sup.1 represents a monovalent hydrocarbon group having up to 8 carbon atoms, R.sup.2 represents a hydroxyl group, a group R.sup.1, a group OR.sup.1 or a group COR.sup.1, R.sup.4 represents a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, an alkenyl group or an aryl group, R' represents a group R.sup.4 or a group X, R" represents a divalent hydrocarbon group which may have nitrogen, oxygen or sulphur present in the carbon chain, X represents a group CO(CHR).sub.n OH in which R represents a hydrogen atom or an alkyl group, a has the value 0, 1, or 2, b has the value 1, 2, or 3, c has the value 1 or 2, the sum of a+b+c=4, m has the value 0, 1 or 2, p has the value 1 or 2, q has the value 0, 1, 2 or 3, r has the value 0, 1 or 2, and n has a value in the range 2 to 7.
The organosilicon compounds are useful in compositions for treating fabrics.
