Non -ion surfactants are a type of chemical, also known as non -ionic surfactant or non -ionic interface active agent. They are surfactants composed of one or more non -ionic compounds. Unlike ionic surfactants, non -ionic surfactants do not produce ions in the aquatic solution.
The molecular structure of the non -ion surface activated agent is usually composed of a hydrophilic head and a hydrophobic tail. The hydrophilic head has hydrophilicity and can interact with water molecules, while hydrophobic tails are hydrophobic and like to interact with oily or fatty substances. This structure allows non -ionic surfactants to establish a stable interface between water and oil at the same time and regulate the interaction between them.
Non -ion surface active agents have many characteristics and applications, including the following aspects:
Mildness: Compared with ionic surfactants, non -ion surfactants usually have lower irritation and toxicity, and have less impact on skin and environment.
Polarity adjustment: Non -ion surface active agents can regulate the polarity of the solution, change its moisture and surface tension, and thus have good wetting, decentralized and emulsifying effects.
Stable lotion: non -ion surfactants are often used to prepare stable emulsion systems, such as cream, lotion, emulsion, etc. They can disperse water and oil to each other and maintain a stable state.
Enhancement of infiltration: Non -ion surfactants can improve the permeability of other substances in cell membrane or skin barrier, and promote the cleaning effect of drug absorption or enhancement of cleaner.
Anti -electrostatic: Non -ion surface active agents can also prevent static electricity from being generated and accumulated, reducing the accumulation and adhesion of solid particles.
Non -ion surfactants are widely used in daily life and industrial fields, such as personal care products, detergents, pesticides, coatings, medical preparations, paper processing, etc. They play an important role in these fields and provide many functions and performance advantages.
