Some green and environmentally friendly and new surfactants

A. Amino acid surfactant: The main raw material of amino acid surfactant is biomass, which has a wide range of sources. In addition, amino acid surfactants have the advantages of less toxic and side effects, milder performance, less irritant to organisms, and good biodegradability. Amino acid surfactants can also be divided into four types: cationic, anionic, nonionic and amphoteric according to the charge properties of the hydrophilic group after ionization in water. Common amino acid surfactants include N-alkyl amino acid type, amino acid ester type, and N-acyl amino acid type5. B. Pineapple Enzyme Surfactant: Pineapple Enzyme Surfactant is made from the remaining tea meal and oil cake after oil extraction from camellia oleifera seeds, pineapple skin, yeast powder pectinase and other fungi are fermented. The molecular structure of its active ingredients Although unclear, experimental data suggest that it has good washing performance6. C.SAA: SAA is a palm oil derivative. As a product of renewable plant raw materials, SAA has received extensive attention. Not only is its production process green and environmentally friendly, but also it can precipitate calcium salts in hard water containing more calcium and magnesium ions. The speed is much slower than commonly used surfactants (LAS, AS)7, that is to say, in practical application, its cleaning ability is also better.
