SILICONE SURFACTANT, AND PREPARATION METHOD AND USE THEREOF

摘要

Disclosed are a silicone surfactant, and a preparation method and the use thereof. The silicone surfactant has a structure as shown in formula (I), wherein c is not 0; a, b, c are all integers and 10< a + b + c < 200; m = 0-40; n = 0-30; x = 3-30; x,m,and n are all integers, and m and n are not both 0; R is a C6 - 20 linear or branched long-chain alkyl, or an alkyl phenyl; and R' is H, CH3, C2H5, C3H7, or C4H9. The silicone surfactant has a novel structure, and an excellent emulsifying ability. The silicone surfactant has a good emulsifying ability for polydimethyl siloxanes and a variety of modified polydimethyl siloxanes in a very wide viscosity range. A good emulsifying effect can be achieved using the surfactant alone without formulating with other emulsifiers, and the emulsifying process thereof is simple and convenient to use without needing any homogenizer or any other special emulsifying process, in order to obtain a stable O/W type silicone oil emulsion.
