Abstract
Liquid 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 liquid compositions herein unexpectedly provide through-the-wash softening benefits comparable to what can be obtained from the utilization of conventional cationic rinse-softeners.
Claims15
A liquid detergent composition capable of providing desirable textile benefits inclusive of softness, containing:
- (a) from 5% to 70% by weight of a surface-active agent selected from the group of anionic, nonionic, amphoteric and zwitterionic surface-active agents and mixtures thereof;
- (b) a liquid carrier;
- and
- (c) from 0.05% to 5% by weight of an organo-functional poly-di-C.sub.1-4 -alkyl siloxane textile treatment agent having the general formula:
- ##STR9## wherein R=C.sub.1-4 -alkyl;
- n is an integer from 1 to 6;
- Z is ##STR10## whereby X and Y are, selected independently, --H;
- --C.sub.1-30 -alkyl;
- --C.sub.6 -aryl;
- --C.sub.5-6 -cycloalkyl;
- --C.sub.1-6 --NH.sub.2 ;
- --CO--R;
- with the proviso that the nitrogen can be quaternized such as to represent ##STR11## whereby W can be selected from X or Y;
- or Z is ##STR12## whereby P and M are --COOH;
- --CO--NR'.sub.2 ;
- or C.sub.1-2 -alkyl;
- with the further proviso that the degree of substitution, i.e., the molar proportion of silicones carrying a substituent other than a C.sub.1-4 -alkyl group to total silicones is in the range from 0.01 to 0.7.
A substantially unbuilt liquid detergent composition capable of providing desirable textile benefits inclusive of softness containing:
- (a) from 25% to 55% by weight of a surface-active agent selected from the group of anionic, nonionic, amphoteric and zwitterionic surface-active agents and mixtures thereof;
- (b) a liquid carrier;
- and
- (c) from 0.05% to 5% by weight of an organo-functional poly-di-C.sub.1-4 -alkyl siloxane textile treatment agent having the general formula:
- ##STR13## wherein R=C.sub.1-4 -alkyl;
- n is an integer from 1 to 6;
- Z is ##STR14## whereby X and Y are, selected independently, --H;
- --C.sub.1-30 -alkyl;
- --C.sub.6 -aryl;
- --C.sub.5-6 -cycloalkyl;
- --C.sub.1-6 --NH.sub.2 ;
- --CO--R;
- with the proviso that the nitrogen can be quaternized such as to represent ##STR15## whereby W can be selected from X or Y;
- or Z is ##STR16## whereby P and M are --COOH;
- --CO--NR'.sub.2 ;
- or C.sub.1-2 -alkyl;
- with the further proviso that the degree of substitution, i.e., the molar proportion of silicones carrying a substituent other than a C.sub.1-4 -alkyl group to total silicones is in the range from 0.01 to 0.7.
A Liquid built detergent composition capable of providing desirable textile benefits inclusive of softness containing:

- (b) a liquid carrier;
- (c) from 5% to 30% by weight of a detergent builder;
- and
- (d) from 0.05% to 5% by weight of an organo-functional poly-di C.sub.1-4 -alkyl siloxane textile treatment agent having the general formula ##STR17## wherein R=C.sub.1-4 ;
- n is an integer from 1 to 6;
- Z is ##STR18## whereby X and Y are, selected indepedently, --H;
- --C.sub.1-30 -alkyl;
- --C.sub.6 -aryl;
- --C.sub.5-6 -cycloalkyl;
- --C.sub.1-6 --NH.sub.2 ;

- with the proviso that the nitrogen can be quaternized such as to represent ##STR19## whereby W can be selected from X or Y;
- or Z is ##STR20## whereby P and M are --COOH;
- --CO--NR'.sub.2 ;
- or C.sub.1-2 -alkyl;
- with the further proviso that the degree of substitution, i.e., the molar proportion of silicones carrying a substituent other than a C.sub.1-4 -alkyl group to total silicones is in the range from 0.01 to 0.7.
