Features of amino acid surfactants-Surface Chemical Industry

Features of amino acid surfactants

Amino acid surfactant has been beginning research more than 40 years ago, which is a biomass-based surfactant, the molecule of amino acid surfactant has amino acid backbone structure, it has high safety to the environment and organisms, affinity for skin and hair, in addition to the general features of surfactant, also has some unique features.

一. Features

A. Excellent surface activity

N- glutamate surfactant have excellent decontamination, anti-calcium, foaming and emulsifying, including sodium cocoyl glutamate, disodium cocoyl glutamate, potassium cocoyl glutamate, sodium lauroyl glutamate.

B. Good biodegradability

Amino acid surfactant use renewable materials as raw materials, have good biodegradability, amino acid structure can be broken down into fatty acid and amino acid by enzymes in human body.

C. High safety

Researchers conducted subacute tests, chronic toxicity tests, mucosal irritation and other tests on white mice and rabbits, the result show amino acid surfactant have very lower irritation than other commonly used surfactant.

D. Strong antibacterial ability

Amino acid surfactants have antibacterial effects on Gram-positive bacteria and some filamentous bacteria.

二. Application of Amino Acid Surfactant

Amino acid surfactant have good wettability, foaming, antibacterial, anti-corrosion, antistatic abilty, toxic free and safe, mild of skin, degradation products are amino acid and fatty acid, hardly no impact on environment, and have good compatibility with other surfactant, widely use in personal daily care product (facial cleanser, shower gel, bubble bath, shampoo, mask, toothpaste, shaving cream, baby care products etc), detergent, food, medicine etc. Especially in daily care products, already formed with amino acid surfactant as main cleaning agent to manufacture amino acid green daily care products.

Daily care products use amino acid surfactant have: sodium lauroyl alaninate, sodium lauroyl glutamate, sodium cocoyl glutamate, sodium lauroyl sarcosinate, sodium methyl cocoyl taurate etc. In hard water use amino acid surfactant as raw materials, facial cleanser has good detergency and foaming properties, can increase skin radiance without irritating skin and eyes, sspecially suitable for sensitive skin and babies use.
Also can improve daily care product hard to squeeze out the hose due to solidification when used at lower temperatures.

三. The main role of amino acid surfactants in daily care products can be summarized as follows:

A. Good absorption and moisturizing effect: Amino acid molecular structure is simple, easily absorbed by the skin, amino acids repair damaged keratin, make stratum corneum conserve and lock moisture to help moisturize.

B. Anti-oxidation and anti-aging: Amino acids have antioxidant properties, can remove hydroxyl radicals to a certain extent, daily care products use amino acid surfactant as main ingredient can resist free radicals and delay aging,

C. Anti-acne effect: Skin acne to a large extent is caused by the imbalance of water and oil, daily care products added with amino acids surfactant can make the skin better lock moisture, maintain skin's water and oil balance.

D. Improve skin function: Amino acids can improve skin immune function, enhance lymphatic system detoxification and improve sensitivity, has good improvement effect on skin.

Use amino acid surfactant as raw material to manufacture daily care products, it is a sunrise industry, its market is huge, it contains business opportunities also are huge.
