Surface active agents play an important role in many different fields. Here are some of the main functions of surfactants:
Moisturizing agent: Surface active agents are one of the main components of common cleaner (such as detergent, hand -toilet, shampoo, etc.). They can reduce the surface tension of the liquid, make it easier to moist and penetrate, and effectively remove dirt and fat.
Wetting agent: The surfactant can change the contact angle between the liquid and the solid surface, and improve the wetting of the liquid on the solid surface. This is very important for applications such as coating, spray, printing, etc.
Emulse agent: Since the surfactant has hydrophilicity and hydrophobic parts at the same time, they can establish a stable emulsification system between water and oil. This is very important for foods, creams and other products in industries such as food, medicines, cosmetics.
Differentians: Surface active agents can disperse solid particles suspended in liquid to prevent them from gathering and precipitating. This has played an important role in industries such as pigmentation, ink, and particle preparations.
Import enhanced agent: Surface activity agent can improve the penetration of other substances in cell membrane or skin barrier, promote the absorption of drugs, or enhance the cleaning effect of the cleaner.
Foaming agent: Surface active agent can reduce the surface tension of the liquid and produce rich foam. This is essential for the user experience of detergents, hand -washing, shampoo and other products.
Anti -static agent: Surface active agent can prevent the generation and accumulation of static electricity, reducing the accumulation and adhesion of solid particles.
Surface modified agent: Surface active agent can form a layer of film on the surface of the material, thereby improving the performance of the material, such as increasing soluble, antioxidant, and abrasion resistance.
The above are some common functions of surfactants, and they play important functions and applications in various fields.
