In the cosmetics (including washing, skin moisturizing, eye gel, shampoo and so on)as emulsifiers, moisturizing agent, wetting agent, thickening agent, PH equilibrium catalyst. In cosmetic formulations for the soap and fatty acid neutralization, and sulfated fatty acid and ammonium salt. Triethanolamine is commonly used asemulsifier in emulsion cream formulations, using triethanolamine cream products withfine paste, paste the bright characteristic, phase stability on the other triethanolamineand senior fatty acid or fatty alcohol to form colloidal good, product quality is stable,can accommodate additional proportion high. Triethanolamine containing Carbopolacid polymer gel is the most commonly used neutralizer, triethanolamine withcarbomer carboxyl neutralization, the formation of high molecular structure stability,achieve results thickening and moisturizing. Medicinal materials. Can be used ascasein, shellac, dyes and other solvents. Can also be used as a fiber treatment agent, preservative additive, plasticizer, photographic developer additive, engine carbon deposit preventing agent etc.. As additives plasticizer, lubricant or neutralizing agent, dispersing agent, corrosion inhibitor and dye resin etc.. Can also be used forsynthesis of surface active agent, stabilizer.
