& The research on amino acid surfactants began many years ago. According to relevant research and experiments, amino acid surfactants are biomass-based surfactants. Because their molecules contain amino acid skeleton structures, they are harmful to the environment and organisms. It has high safety in the body and has a certain affinity for skin and hair. It can achieve the characteristics of being gentle to the skin and non-irritating to the eyes. In addition to the general characteristics of surfactants, amino acid surfactants also have excellent surface activity. , good biodegradability, high safety and strong antibacterial ability. So what are the practical applications of amino acid surfactants in the daily chemical industry? Amino acid surfactants have good wetting, foaming, antibacterial, antistatic and anti-corrosion properties. They are non-toxic and harmless to human skin. Since the H value is weakly acidic and close to human skin, it can be gentle. It's skin-friendly and won't cause irritation. Its degradation products are amino acids and fatty acids, which are basically non-toxic and harmless to the environment. It has good compatibility and can coexist with other surfactants. It can be widely used in cosmetics (facial cleanser, shower gel, facial mask and shampoo, etc.), food , medicine and health, mineral flotation, petroleum fuel, metal cleaning and processing, pesticide preparation, etc.
Amino acid surfactants that are widely used in care products include: lauroyl glutamic acid, esteryl sarcosine, sodium cocoyl methyl taurate, etc. For example, magnesium salt and diamond salt of lauroyl glutamic acid are the base materials of block purifiers, which can overcome some shortcomings of fatty acid soap and can be used in hard water. In addition, the facial cleanser formulated with this type of surfactant as raw material has good foaming and cleaning power, can increase the gloss of the skin, will not cause irritation to the eyes and skin, and is suitable for children and sensitive skin. Be applicable.
As amino acid surfactants are more and more widely used in the market, people have also made significant research results on the application of amino acids in the daily chemical industry, and have developed many green daily chemical products with amino acids as the main ingredients. , including more than a dozen varieties such as facial cleanser, shampoo, shower gel, and hand sanitizer. The amino acids used are: proline, alanine, leucine, glycine, serine and other natural amino acids. At the same time, when using amino acid cosmetics, you can achieve beauty and beauty effects by applying and spraying it on the surface of the skin and allowing the skin or hair to be washed directly.
The main advantages of using amino acid surfactants in such products are: first, good absorption and good moisturizing effect. Because the molecular structure of amino acids is very simple, it can be quickly absorbed by the skin. Amino acids can repair damaged cuticles on the skin, allowing the cuticles to conserve and lock in moisture, thereby achieving a moisturizing effect. Second, it has antioxidant and anti-aging effects. Amino acids have antioxidant properties. According to relevant studies, amino acids such as alanine have good effects on removing hydroxyl free radicals. In addition, daily necessities with amino acids as the main ingredients can resist free radicals and delay aging, so they are favored by women. Third, it has anti-acne effect. Skin acne is mostly caused by an imbalance of water and oil. Adding amino acids to daily necessities can help the skin better lock in moisture and maintain a balance of water and oil. Fourth, improve skin and soften texture. Amino acids can effectively improve the immune function of the skin, accelerate the detoxification process of the lymphatic system, improve anti-sensitivity, and have a good improvement and texture relaxation effect on sensitive skin.
