Detergent compositions and processes of making thereof

DETAILED DESCRIPTION What we claim is: 1.
A foam-controlled detergent composition comprising from 1.
5% to 100% of a mixture of: (a) alkoxylated nonionic surfactant, (b) polydimethylsiloxane foam controller dispersed in at least part of the alkoxylated nonionic surfactant, and (c) siloxane-oxyalkylene copolymer as dispersing agent for the polydimethylsiloxane foam controller, wherein the weight ratio of alkoxylated nonionic surfactant to polydimethylsiloxane foam controller is in the range from 10:1 to 100:1 and the weight ratio of polydimethylsiloxane foam controller to siloxane-oxyalkylene copolymer is in the range from 2:1 to 20:1.
2.
A composition according to claim 1 wherein the polydimethylsiloxane foam controller is dispersed in the nonionic surfactant together with particulate silica in a weight ratio of polydimethylsiloxane to silica in the range from 20:1 to 200:1.
3.
A composition according to claim 2 wherein the weight ratio of alkoxylated nonionic surfactant to polydimethylsiloxane foam controller is in the range from 25:1 to 65:1 and the weight ratio of polydimethylsiloxane foam controller to siloxane-oxyalkylene copolymer is in the range from 5:1 to 15:1.
4.
A composition according to claim 1 wherein the siloxaneoxyalkylene copolymer has the general formula I: R.
sub.
a SiY.
sub.
4-a I wherein a is 0 or an integer from 1 to 3, R is an alkyl group containing from 1 to 30 carbon atoms, or a group of formula II: R'(OR').
