There are many ways to classify surfactants. According to the source of surfactants, surfactants are usually divided into synthetic surfactants, natural surfactants and biological surfactants.
1. Synthetic surfactant
Synthetic surfactant refers to the surfactant synthesized by chemical methods using petroleum and natural gas as raw materials.
2. Natural surfactants
At present, the most popular natural surfactants are amino acids, and its main characteristics are relatively mild, low irritation to the skin and eyes, and good biodegradability. The main raw material of amino acid surfactant, its sources are wide. And the amino acid surfactant has the advantages of less toxic side effects, mild performance, little irritation to organisms, and good biodegradation performance.Amino acid surfactants can also be divided into cationic, anionic, non-ionic and amphoteric types according to the charge properties of hydrophilic groups after ionization in water.
Biosurfactants are compounds that have the characteristics of surfactants produced by a variety of microorganisms such as bacteria, yeast and fungi.
Surfactants as the most important ingredients in daily chemicals, in the development and application of natural raw materials should be vigorously used, as far as possible to avoid the use of irritating ingredients to the skin, in order to reduce the chemical ingredients to the human body brought a variety of hazards, in the face of the continuous reduction of resources and human environmental awareness of the trend, the development of green surfactants will become the sustainable development of the industry to provide possibilities.
