Abstract

Stable, low-viscosity dispersions of polysiloxanes containing amino or amido groups can be obtained, even at comparatively high concentrations and/or pH values, by adding a product of the formula EQU R1--CH(X)--Y--O--R2 (R1 is H, CH.sub.3 ; X=OH, NH.sub.2 ; R2=C.sub. -C.sub.4 -alkyl, unsubstituted or substituted by OH or OR3; R3=C.sub.1 -C.sub.4 -alkyl, unsubstituted or substituted by OH) to the dispersions. The dispersions are suitable for the treatment of fiber materials, especially textiles, to which a soft handle is thereby imparted.
