Abstract
Compositions and a method of delivering a humectant to a surface such as skin by forming a reaction product of the humectant with an organosilicon compound. The reaction product is applied to the skin surface and contacted with moisture which causes the reaction product to undergo hydrolysis on the skin surface. This releases free humectant onto the skin surface and the silanol functional organosilicon compound formed as a result of the hydrolysis can be utilized on the skin surface as a durable water repellent and softening ingredient for the skin.
