This review is intended to supply the practicing chemist with a working knowledge of the chemistry of silicone compounds. It has been divided into two parts, the first dealing with basic chemistry of silicones [O'Lenic, A.J., JSD 2 , 229 (2000)] and the second with silicone‐based surfactants, specifically dimethicone copolyols and their derivatives. This is the second part of the review. Although silicone compounds have been known for over 50 yr, the chemistry of these materials remains elusive to the average formulating chemist. This is indeed unfortunate, since the chemistry of the silicon atom and silicone compounds is every bit as wide in scope and rich in content as the chemistry of the carbon atom and the surfactant chemistry upon which it is based. This article will deal with the various methods of delivering silicone from aqueous systems. The two approaches are (i) to make emultions that contain silicone oil and a surfactant pair and the (ii) to make modify the molecule chemically to make the product more water‐compatible. Both approaches find applications in a variety of industrial applications, with different challenges to the formulator.
