Molecular Structures and Preparation of Non-ionic Silicone Surfactants Du Yang, Liu Zuliang, Lu Chunxu (School of Chemical Engineering, Nanjing University of Science and Technology, Nanjing 210094) Abstract Silicone surfactants are an important class of novel surfactants. Due to their unique properties, such as high surface active, super wetting and spreading abilities, good heat-resistance and physiological safety, they are used in a wide range of applications, including polyurethane foam and textile manufacture, paints and coatings, cosmetic and as agrichemical adjuvants. In this paper, the molecular structures and common synthetic methods of non-ionic siloxane polyether copolymers are reviewed. The side-reactions during the manufacturing processes are discussed in detail.
