Organic silicone emulsion (abbreviated as silicone emulsion) is an emulsion composed of water-in-oil silicone oil, water and surfactant.

Organic silicone emulsion is mainly used as silicone oil fabric softening finishing agent. The first generation of organic silicone fabric finishing agent is a mechanical mixture of dimethyl silicone oil and hydrogen silicone oil (and its derivatives). The second generation of organic silicone fabric finishing agent is hydroxyl-terminated polydimethylsiloxane emulsion, which is formed by emulsion polymerization of octamethylcyclotetrasiloxane monomer, water, emulsifier, catalyst and other raw materials under certain conditions. Since polymerization and emulsification are completed in one step, it has the advantages of short working time, high efficiency, simple equipment and convenient operation. The obtained emulsion is very stable, the particles are very uniform, and the obtained polymer has active groups (hydroxyl groups) at both ends. It can further react to form a film, which is conducive to improving the application effect of the emulsion, which is beyond the reach of mechanical emulsified silicone oil.
