A detailed description of one of the surfactants

Surfactants are an important class of fine chemicals. When they are dissolved in aqueous solution at a very low concentration or dispersed, they are preferentially adsorbed on the surface or other interfaces of the solution, so that the surface or interfacial free energy (or surface tension) is significantly reduced and the interfacial state of the system is changed.

The molecules of surfactants are generally composed of hydrophobic and hydrophilic groups, so they are called amphiphilic compounds.

The molecule has an asymmetric structure, part of which is easily soluble in water and has hydrophilic nature, called hydrophilic group, common groups include carboxyl group, sulfate group, sulfonic acid group, phosphate group and quaternary ammonium group, etc.; the other part is insoluble in water but easily soluble in oil and has lipophilic nature, called lipophilic group, also called hydrophobic group, generally straight chain hydrocarbon (aromatic) containing C8~C18 carbon, such as carbon radon chain, carbon fluorine chain, polysiloxane and polyoxypropylene group Translated with www.DeepL.com/Translator (free version)

Baryonic surfactants and biosurfactants, molecules with at least two or more hydrophilic groups (polar groups), or at least two or more lipophilic groups (hydrocarbon chains, carbon silicon chains or carbon fluorine chains), and linked by chemical bonds at or near the hydrophilic groups, are called baryonic surfactants

Compounding Properties of Cationic Surface Actives in Anionic Systems

There are many determinants of the effect of anion-cation surfactant compounding on surface activity, and there is a synergistic effect in the case of suitable structure of both parties. In the mixed system of anion-cation surfactants, due to the strong electrostatic attraction of positive/negative ions between molecules, it is easy to form a rod-shaped colloid

Classification and properties of green surfactants

Surfactants are indispensable additives. Adding a certain amount of surfactant solvents to detergents can enhance their solubility and detergency, but due to their toxicity, they can cause significant skin irritation. The use of surfactants in large quantities is also potentially harmful to the ecosystem. In order to meet the increasing demand for health care and
