Cationic surfactant - Names and Identifiers
Cationic surfactant - Introduction
Cationic surfactant is a class of compounds with Cationic surface activity. Their main feature is that the molecule contains one or more positively charged ionic groups, usually nitrogen, phosphorus or sulfur ions and other elements. The Cationic surfactant has the following properties:
1. Surface activity: Compared with anionic and Nonionic Surfactants, Cationic surfactant has lower surface tension in water, which can reduce the surface tension of the liquid and make the liquid more easily wet and expand.
2. Solubility: Cationic surfactant has good solubility in water and can form a complex with anionic surfactants.
3. Micelle formation: at an appropriate concentration, the formation of a micelle structure of the Cationic surfactant is conducive to emulsification, dispersion and stable concentrated liquid.
Cationic surfactant is widely used in many fields, including:
1. Cleaning agents and detergents: Cationic surfactant can effectively clean oil and stains, and is often used in cleaning products such as washing powder, detergent and shampoo.
2. Softener: Cationic surfactant can reduce the electrostatic attraction between fibers and make clothes soft and smooth. It is often used in softeners and fabric care products.
3. Antistatic agent: cationsurfacant can adsorb with materials with negative charges on the surface to reduce the generation and accumulation of static electricity, and is used in the electronics and textile industries.
4. Antibacterial agent: some of the Cationic surfactant has good sterilization and disinfection effect, commonly used in medical, health and agricultural fields.
There are two main methods for preparing the artificial surfactant: synthesis and extraction. The synthetic methods include quaternization reaction, nucleophilic substitution reaction, sulfurization reaction, etc. The extraction method is extracted from natural raw materials, such as seaweed, animal hair and so on.
