Alkyl glycosides are easily biodegradable in natural environment

Alkyl glucosides have the advantages of ordinary nonionic and anionic surfactants: high surface activity, high viscosity, rich foam, fine and stable. It has obvious synergistic effect with other surfactants; It has strong dispersibility to calcium soap and can be used in hard water; Very low irritation to epidermis, mucosa and living cells; It is easy to biodegrade in the natural environment and has less environmental pollution. APG is formed by condensation of starch or its hydrolyzed sugar with fatty alcohol. The source of raw materials is very wide, which has attracted more and more attention in recent years.

Alkyl glycosides have no irritation to human scalp and eyes. The combination of anionic surfactant and anionic surfactant can improve the surface activity. Under the condition of achieving the same shampoo effect, it can reduce the dosage of surfactant and further reduce the irritation. It can be used as the raw material of children's shampoo. Meanwhile, CAPG has obvious foam advantages, and its foam performance is better than that of alcohol ether and AES, AESS and bisexual beet. It has good foam stability and good stability with anionic surfactants. It can be used as the main surfactant for shampoo.

At the same time, cationic alkyl glycosides contain polyhydroxy and quaternary ammonium salts, their hydrophilic groups are adsorbed on the hair surface, and the hydrophobic groups are far away from the hair surface and arranged in a directional manner to form a protective film, which eliminates the hair static electricity, gives the hair smooth and luster, and is easy to comb. It is a good conditioner and realizes one dose of multi-function. The formula of quaternary ammonium salt shampoo containing cationic alkyl polyglycoside is shown in the table.

Tableware detergent has been widely used in people's life. Most families use hand washing, while hotels and restaurants use machine washing. Hand washing has strict requirements on irritation, while machine washing has higher requirements on the number of dishes. However, no matter which washing method must meet the conditions of low toxicity, strong degreasing ability, easy cleaning and no residue after washing, it can also have the function of disinfection and sterilization.

In recent years, people have been committed to studying the "two in one" meal lotion integrating washing and decontamination. A direct method is to add disinfectant, oxychloride bactericide, iodine, cationic surfactant, etc. to the anionic meal lotion. Oxychloride products are unstable and difficult to store for a long time, and adding cationic surfactant has become a simple and direct method, However, at present, there are few cationic surfactants that can be combined with anionic surfactants, so people use the coating process to make the cationic surfactant into microcapsules and add them to the meal lotion, and break the microcapsules during use, so as to realize the combination of washing and elimination. However, this method has complex process, high cost and unsatisfactory effect, Therefore, people directly add oxidized amine surfactants to anionic meal lotion, which improves many properties, but the bactericidal effect is not ideal.
