  • Granular detergent compositions containing organo-functional polysiloxanes
    Patent number: 4585563
    Abstract: Granular built detergent compositions containing additive levels of organo-functional polysiloxanes are disclosed. The siloxanes are derived from poly-di-short-alkyl siloxanes by substituting part of the alkyl moieties by specific organo-functional groups, preferably amino-groups, with the proviso that the degree of substitution is in the range from 0.01-0.7. The granular detergent compositions herein unexpectedly provide through-the-wash softening benefits comparable to what can be obtained from the utilization of conventional cationic rinse-softeners. An additional benefit originates from the "dry-softening" feel of the composition herein as compared to the "greasy" feed conferred by conventional cationic rinse softeners.
