alkyl sulfate | ammonium dodecyl sulfate, sodium dodecyl sulfate (K12) and triethanolamine dodecyl sulfate (LST) are three kinds of alkyl sulfate anionic surfactants commonly used in the field of industrial cleaning. alkyl sulfate belongs to high-carbon alcohol sulfate. in 1928, Bohme company in Germany found that high-carbon alcohol sulfate salt has better properties than soap, and has the effects of wetting, decontamination and dispersion. Six countries in the world, including Japan, have obtained patent rights. It is an anionic surfactant that has received worldwide attention. With the rapid development of the fiber industry, high-alcohol sulfate salts as fiber additives have its outstanding characteristics, so the demand has increased sharply. High-carbon alcohol sulfate overcomes the shortcomings of soap, and has better performance than soap. It has high solubility in water, and will not form a gel like soap even in a high-concentration aqueous solution., And still maintain a liquid state; its aqueous solution is not alkaline but neutral, so it will not damage or cause curl; it is not easy to salt out like soap, therefore, it can also be used in hard water or seawater. Even under alkaline to weakly acidic conditions, it is not easy to be hydrolyzed and has stable performance. high alcohol sulfate sodium salt can be used as industrial cleaning agent, soft smoothing agent, textile oil agent and emulsifier for emulsion polymerization. In addition, it can also be used as household detergents, kitchen liquid detergents, etc., as well as emulsifiers and foaming agents for toothpaste, cosmetics, pharmaceutical ointments, etc. Its ammonium salt and triethanolamine salt are used as detergents and foaming agents, because they are more soluble and less irritating than sodium salt, and are used in shampoo, bath liquid and high-grade detergent formulations. among the representative varieties are sodium dodecyl sulfate (K12), ammonium dodecyl sulfate (LSA), triethanolamine dodecyl sulfate (LST), etc. This information is edited by Xiaonan. |
use | 1. as the main component or auxiliary component of detergent, foaming agent, it is widely used in the field of personal care products such as toothpaste, shampoo, hand sanitizer, shampoo, shower gel, etc. 2. Compared with sodium dodecyl sulfate: ammonium dodecyl sulfate has lower toxicity and irritation, so it is widely used in personal care products such as shampoo and shower gel. 3. in view of the irritation of ammonium dodecyl sulfate, the addition amount should not exceed 1% in products used in direct and long-term contact with human body, such as skin care products. Figure 1 is the reference quality standard and inspection method for ammonium dodecyl sulfate. |
