## Abstract

Foaming alcohol compositions with selected dimethicone surfactants are disclosed. The dimethicone surfactants are PEG-8 to PEG-12 linear dimethicone surfactants and in particular PEG-10 linear dimethicone surfactant. The compositions are useful as antimicrobial products and in particular handcare or skincare products.
