Abstract
Granular, phosphate-reduced, builder-containing detergent compositions containing a combination of natural layer silicates and fatty acid condensates. The fatty acid condensates are prepared by reaction of fatty acid triglycerides and hydroxyalkyl polyamines. The detergent compositions have an excellent softening effect both at low and high washing temperatures. The compositions provide synergistic softening effects, particularly at low temperatures.
Claims18
A granular, phosphate-reduced, builder-containing detergent composition containing the combination consisting essentially of;
- (a) from about 4 to about 20% by weight of natural layer silicate, and
- (b) from about 0.3 to about 10% by weight of fatty acid condensate obtained by reaction of a fatty acid triglyceride with a hydroxyalkyl polyamine, based on the weight of said detergent composition wherein the ratio by weight of said layer silicate to said fatty acid condensate is between 5:1 and 1:2.
A granular detergent composition containing the combination consisting essentially of;
- (a) from about 4 to about 20% by weight a natural layer silicate, and
- (b) from about 0.3 to about 10% by weight of a fatty acid condensate obtained by reaction of a fatty acid triglyceride with a hydroxyalkyl polyamine, in a weight ratio of from about 5:1 to about 1:2, respectively.
A process for softening a fabric comprising contacting said fabric with a solution of a phosphate-reduced, builder-containing detergent composition containing the combination consisting essentially of;
- (a) from about 4 to about 20% by weight of natural layer silicate, and
- (b) from about 0.3 to about 10% by weight of fatty acid condensate obtained by reaction of a fatty acid triglyceride with a hydroxyalkyl polyamine, based on the weight of said detergent composition wherein the ratio by weight of said layer silicate to said fatty acid condensate is between 5:1 and 1:2.
A process for softening a fabric comprising contacting said fabric with a solution containing the combination consisting essentially of;
- (a) from about 4 to about 20% by weight of a natural layer silicate, and
- (b) from about 0.3 to about 10% by weight of a fatty acid condensate obtained by reaction of a fatty acid triglyceride with a hydroxyalkyl polyamine, in a weight ratio of from about 5:1 to about 1:2, respectively.
