Silicone surfactants are a new generation of surfactants that have been studied as hot spots with the rise of new silicone materials in recent years. The surface activity of their hydrophobic silicon-oxygen chains is very high, which can significantly reduce the surface tension of water. It is a kind of high-efficiency surfactant, so it has become one of the research hotspots in the field of surfactants.

Making process
High hydrogen-containing silicone oil to synthesize modified silicone oil as polyurethane foam stabilizer, paint leveling agent, fabric finishing agent, polyurethane foam stabilizer (high-hydrogen-containing silicone oil, low-hydrogen-containing silicone oil)

Hydrogen-terminated silicone oil can be used as the raw material of linear modified silicone oil, and can be used to prepare polyether modified silicone oil, ternary block copolymer silicone oil and other products, which can be used as textile softener, leather finishing agent, etc.

Structural Principles
The molecular structure of surfactants is amphiphilic, with a hydrophilic group on one side and a hydrophobic group (lipophilic group) on the other side.

Classification
1. Classification by hydrophilic group
(1) Ionic surfactants
①Zwitterionic surfactant
②Cationic surfactant
③Anionic surfactants

(2) Nonionic surfactants

2. Classification by hydrophobic group
(1) Silyl type
(2) Siloxane-based type

Characteristic
Low surface tension: the main chain is very flexible, and the intermolecular force is much weaker than that of hydrocarbons
Weather resistance: there is no double bond, so it is not easy to be decomposed by ultraviolet light and ozone, and has a long life

Application
Cosmetics: humectants, preservatives, foam stabilizers, conditioners
Plastic industry: foam stabilizer, foam stabilizer
Agriculture: Foliar Absorbent Aids
Coating: leveling agent
Leather: slip agent, brightener, water repellent
