Surfactant is known as "industrial monosodium glutamate". It is not only widely used in chemical industry and many other traditional industries and technology fields, but also in high-tech fields such as materials, energy and life science. Surfactants play an important role in cosmetics because of their emulsification, dispersion, solubilization, foaming, cleaning, lubrication and softness. In addition, the performance of surfactants used in cosmetics is not only its single performance, but also its multiple performance. Therefore, surfactants are indispensable raw materials in the production of cosmetics and widely used in cosmetics. A kind of

When the surface adsorption reaches saturation, the surfactant molecules cannot continue to adsorb on the surface, and the surfactant molecules transfer into the solution. Because of the mutual attraction between the lipophilic groups, the hydrophilic groups in the lipophilic groups associate outward to form micelles whose size does not exceed the scope of colloidal particles, and which are stably dispersed in water. The lowest concentration of micelle formed by the association of surfactant molecules in solvent is the critical micelle concentration. When the critical micelle concentration is reached, the dispersion system will change from a real solution to a colloidal solution. At the same time, there will be sudden changes in the dispersion system, such as the decrease of tension, the enhancement of solubilization, the increase of foaming performance and decontamination, osmotic pressure, conductivity, density and viscosity.

According to the characteristics of molecular composition and the dissociation properties of polar groups, they can be divided into ionic and non-ionic surfactants. At the same time, ionic surfactants are divided into anionic, cationic and two kinds of ionic surfactants. A kind of

Anionic surfactants are widely used in cosmetics. They have rich foaming, good emulsification, cleaning power of adaptability and special skin affinity. It can meet the requirements of hair cleanser, and can be used in many facial cleansers, bath milk and children's washing products. A kind of

Cationic surfactants can be used in hair care products, including hair antistatic agents, to make hair more flexible. In some products, they can also be used as emulsifiers. Quaternary amine compounds are the most widely used cationic surfactants in cosmetics. They show a strong directness to skin and hair, which can make hair easier to comb, so as to improve the feeling and luster of hair.
