Abstract
A method of enhancing the durability of an emollient material on a substrate by forming a mixture of an emollient material and an effective amount of an organosilicon compound, and applying the mixture to the substrate to be treated. The organosilicon compound is either an aminofunctional, amidofunctional, or carboxyfunctional, polysiloxane. A skin conditioning composition of enhanced durability is also disclosed which is a mixture of an emollient material and an effective amount of an organosilicon compound which is either an aminofunctional, amidofunctional, or carboxyfunctional, polysiloxane.
Claims18
A method of enhancing the durability of an emollient material on human skin comprising forming a mixture of an emollient material and an effective amount of an organosilicon compound, and applying the mixture to the skin to be treated, the organosilicon compound being a carboxyfunctional polysiloxane having the formula
- QMe.sub.2 SiO(Me.sub.2 SiO).sub.x (MeRSiO).sub.y SiMe.sub.2 Q
- wherein Me is a methyl radical, R is a carboxyfunctional radical, said carboxyfunctional radical being selected from the group consisting of carboxyalkyl radicals and carboxythioalkyl radicals, Q is selected from the group consisting of R, Me and OH groups, x has a value of 1 to 1000, and y has a value of 1 to 100.
