The application of surfactants in life

In recent years, China's surfactant industry has developed rapidly, and the output continues to expand and the variety continues to increase. This is due to the wide application of surfactants in industrial and agricultural production, and more importantly, due to the increasing demand for household washing supplies and other daily necessities in daily life.

The main functions of surfactants in cosmetics include emulsification, dispersion, solubilization, foaming, cleaning, lubrication and softening.

Surfactants are widely used in cosmetics and play an important role. The performance of the surfactant used in cosmetics is not only its single performance, but the use of its various properties, therefore, the surfactant is an indispensable raw material in the production of cosmetics, and is widely used in cosmetics. Specifically, cosmetics have certain requirements for surfactants used as important raw materials, including: surfactants used as raw materials are required to have whitening, moisturizing, delaying skin aging and anti-hair loss functions; The raw materials used as cosmetics must be harmless to the human body, no irritation, no toxicity to the skin and eye mucosa, no pleasant odor, no allergic and other adverse phenomena; The surfactant used as an emulsifier has good compatibility and compatibility, good appearance and use feeling, and requires a pleasant aroma, fine, smooth and soft, good foaming and spreading, and is convenient in production and operation; Surfactants used as cosmetics should have anti-microbial contamination properties and so on.

Surfactants have efficient cleaning and disinfection functions, and have long become the most important component of cleaning products. Surfactants are the main components of detergents, which have a series of physical and chemical interactions with dirt and between dirt and solid surfaces (such as wetting, penetration, emulsification, solubilization, dispersion, foaming, etc.) and obtain washing effects by means of mechanical agitation. The largest and most widely used are anionic and non-ionic surfactants, and cationic and amphoteric surfactants are only used in the production of some special types and functions of detergents.

Household detergents mainly include laundry detergents (such as laundry powder, laundry soap, laundry liquid, laundry cream, laundry sheets, collar net, etc.); Household cleaning products (such as dish soap, floor cleaner, toilet cleaner, household appliance cleaner, etc.); Personal care products (such as shampoo, body wash, hand sanitizer, facial cleanser, etc.) several categories. Surfactants are the main components in household detergents. The development of surfactants has promoted the prosperity of household detergents; The development of household detergents; Driving the growth of surfactants.

With the continuous improvement of people's living standards, people's requirements for food are becoming higher and higher, food in addition to meet the most basic nutritional value, but also should have good color and flavor. Therefore, more and more food additives are used in the food industry, and surfactants are the most common food additives. Surfactants are a class of compounds containing fixed hydrophilic and oleophilic groups in molecules that can be concentrated on the surface of a solution, at the interface of two immiscible solutions, or at the interface of a liquid and a solid to reduce its surface tension or interfacial tension. Surfactants are widely used in the food industry. Adding surfactants to some food production can greatly improve the processing conditions, improve product quality, and extend the shelf life of food. High quality food processing is inseparable from the application of surfactants.
