Enzyme delivery systems, application in water based products

Abstract

Aqueous enzyme delivery systems as well as aqueous cosmetics and personal care products were provided which comprise at least one stabile enzyme and a polyglycerol containing at least 15 carbons. In addition, stabile non-aqueous enzyme delivery systems which are dispersions of at least one enzyme in an non-aqueous viscous liquid as well as a methods for the treatment of human skin in recreational water applications by means of enzymes are provided.
