Detergent

As a liquid washing ingredient, hydroxybetaine has good water solubility in a wide temperature range and good washing effect. It can be applied to high-concentration and high-water-soluble liquid washing ingredients. Alkylamide betaine has strong foaming increase, low irritation, and the foam is stable, and it can be used in detergents and liquid soaps made of shampoo propyl betaine. It has low skin irritation and high safety, and has a soft skin feeling.

 

Cosmetics

Betaine is used as an emulsifier in cosmetic emulsions. Its solution is stable, has good spreadability when applied to the skin, has a good skin care effect, and has good bactericidal properties and is rich in nutrition for the skin.

 

Shampoo

Betaine-based amphoteric surfactants are used in shampoos with anionic and non-ionic surfactants due to their good foaming, decontamination, safety, and resistance to hard water. Reduce irritation and other effects.

 

Textile, printing and dyeing auxiliaries

The development of betaine amphoteric surfactants originated from the application in the textile industry. Betaine amphoteric surfactant is one of the most chemically stable surfactant categories. It maintains amphoteric characteristics and chemical stability in a wide pH range. Therefore, betaine amphoteric surfactant is suitable as a leveling agent, Used as a wetting agent, scrubbing agent, antistatic and softening agent in the sulfation of wool.

 

Emulsifier

Betaine amphoteric surfactants can be used as microemulsifiers and dispersants. When betaine amphoteric surfactants are used in styrene emulsion polymerization, small particles with a narrow distribution (50-100μm) can be obtained. Alkyl betaine amphoteric surfactants are used as emulsifiers for styrene polymerization. When latex is diluted with water and filled into a batch of slime silk, acrylic or nylon carpets, it can reduce stains; dodecyl and tetradecyl beets Alkali can also be used as a suspending agent for the aqueous polymerization of vinyl chloride; most allyl latexes are synthesized in the presence of low-concentration lauryl betaine or coco-betaine; alkyl betaine is used as an emulsifier for cationic latex , With cationic emulsifier, specially used for road paving chemicals, its performance is much stronger than non-ionic emulsifier; betaine amphoteric surfactant can also be used in the preparation of photographic emulsion, stearyl betaine is the preparation and The emulsifier of monomer alkyl acrylate and acrylonitrile in gelatin-compatible polymerized hydrosol. The sol maintains stability in a wide pH range and is used as a photographic emulsion.

 

Oil recovery additives

Betaine amphoteric surfactants are used in secondary oil recovery and tertiary oil recovery, and their dispersibility is particularly beneficial to limestone formations; the displacement of microemulsions containing betaine or acyl betaine amphoteric surfactants can improve oil recovery Rate; Alkyl betaine amphoteric surfactants displace carbonate ore. Because betaine amphoteric surfactants have excellent solubility in saline solution, they will not be precipitated by divalent calcium ions; C12~14 alkyl Chain sulfite betaine is a bactericide for sulfate-reducing bacteria, which can be used for enhanced oil recovery and crude oil refining.

 

Medical and health field

Betaine amphoteric surfactants can be used in medicine, medicine, biology and other related fields. Alkyl betaine has a certain effect with the enantiomeric amino acid and corresponding compound drug molecules; betaine amphoteric surfactant can be used as a transdermal adsorption accelerator for ionic water-soluble drugs; betaine amphoteric surfactant can Enhance the release of active ingredients in ointments containing neomycin sulfate and chloramphenicol; Sultaine is suitable for separating and purifying antigens from biological systems, and can be used as vaccine reagents and diagnostic reagents; made from Sultaine Virus particles have a strong ability to inhibit virus reproduction in the lungs of immunized mice; the aqueous solution of cetyl sultaine is used to delay the mineralization of transplanted tissues, such as artificial heart valve pericardium tissue, which will be fixed before fixation. It is immersed in a solution of sulfobetaine amphoteric surfactant; the aqueous solution of alkyl betaine amphoteric surfactant and non-ionic surfactant is suitable for treating burns and red and swollen skin treatment formula; alkyl betaine amphoteric surfactant Surfactants are also effective in treating gastric ulcers. When used with salicylate drugs, they can reduce or prevent stress-induced or salicylate-induced gastrointestinal ulcers; a solution of octyl sulfobetaine When separating mitochondria, it can prevent the loss of mitochondrial carnitine. When the concentration of sulfobetaine reaches several times the required concentration for transferase inhibition, it can inhibit carnitine acetyltransferase and carnitine palmitate transferase.

 

Other applications

Alkyl betaine amphoteric surfactant is a good leather finishing agent, which can make leather more resistant to dry cleaning; adding betaine amphoteric surfactant to alkenyl rubber can inhibit the blooming of sulfur containing vulcanizing agent; stearin Acyl betaine is a good dispersant, which can improve the efficiency of coal water slurry pelletizing and dust removal; betaine amphoteric surfactants used in coatings have excellent wet adhesion and frost resistance; metal pigment formulations, especially those Aluminum-containing formula can be blended with water-resistant paint to avoid the risk of explosion, and make the coating have a good metallic appearance, smooth surface, good adhesion and water repellency; sulfobetaine amphoteric surfactant Used to prepare magnetic recording materials, when methylsilyl lubricants are coated with betaine amphoteric surfactants, the carrier shortage of high-density information discs exposed to high temperature and relatively high humidity is greatly reduced; containing sulfobetaine amphoteric The resin of the surfactant can uniformly disperse the magnetic powder with ultra-fine particles, thereby enhancing the magnetization; the lauryl amidopropyl betaine is used as one of the components of the acidic aqueous solution to clean the glass fiber. Significant fading occurs; adding betaine amphoteric surfactants to fertilizers can extend the shelf life of liquid fertilizers from 15 to 27 weeks. This is achieved by delaying the formation of magnesium-containing precipitates and is suitable for wet-process phosphoric acid ammoniation Production; Betaine amphoteric surfactant can also be used to electroplate copper, tin, zinc and other metals to obtain bright alloys.
