Time：2024-01-10 Hits：227
Surfactant refers to a substance that can significantly change the interface state of its solution system by adding a small amount. Surfactants are divided into ionic surfactants (including cationic surfactants and anionic surfactants), nonionic surfactants, amphoteric surfactants, compound surfactants, other surfactants, etc.
The molecular structure of surfactants is amphipathic: one end is a hydrophilic group and the other end is a hydrophobic group; the hydrophilic group is often a polar group, such as carboxylic acid, sulfonic acid, sulfuric acid, amino or amine group and its Salts, hydroxyl groups, amide groups, ether bonds, etc. can also be used as polar hydrophilic groups.
Application of surfactants
Surfactants are mainly used in the production of synthetic detergents, emulsifiers, demulsifiers, penetrants, foaming agents, defoaming agents, wetting agents, dispersants, flotation agents, softeners, antistatic agents, waterproofing agents and other additives. agent.
The role of surfactants
Emulsification, wetting, solubilization, dispersion, foaming.

Nonionic surfactant
During the separation process of micellar chromatography, a nonionic (ether product made from a fatty alcohol above C8 and 35 ethylene oxide units, Brij35 or TW-80) surfactant is added to the mobile phase to form a micellar solution , it is selective and can separate hydrophilic and hydrophobic substances at the same time. It also has good separation effect on charged components and non-charged components, and is suitable for separating substances with little difference.
It is used for emulsification, wetting, dyeing assistance, diffusion, washing, etc. It has excellent biodegradability and low-temperature performance, is not affected by water hardness, and is suitable for washing synthetic fibers. It is widely used as leveling agent and stripping agent for various dyes in the textile industry. The general dosage is 0.2~1 g/L.
Used as detergent and other emulsifiers in metal processing
A good raw material for mild detergents, shampoos (such as baby shampoo), body wash, facial cleansers and cosmetics; instead of AES, it can reduce the irritation of the product without increasing the cost.
2. Tween 20 (Tween 20, emulsifier T-20, CAS: 9005-64-5)

Uses of Tween-20:
Tween-20 is a yellow or amber clear oily liquid with a special odor and faint bitter taste.
The relative density is 1.01, the boiling point is >100℃, the flash point is 321℃, the refractive index is 1.472, and the viscosity (25℃) is 0.25~0.40Pa·s.
Tween-20 molecules contain many hydrophilic groups and are miscible with water, ethanol, methanol and ethyl acetate. They are insoluble in liquid paraffin, fixed oil and light petroleum. One part of this product is soluble in 130 parts In cottonseed oil and 200 parts of toluene, the pH of 5% aqueous solution is 5 to 7. The HLB value is 16.7.
Tween-20 is a nonionic surfactant. Gas chromatography stationary solution (use temperature shall not be higher than 120°C) separates and analyzes volatile oils, fatty acid esters, alcohols, ketones and halides.
Water-soluble emulsifier, solubilizer, antistatic agent and fiber lubricant for textile industry.

3. Triton X-100
Chemical Abstracts and other symbols: 9002-93-1, colorless or almost colorless transparent viscous liquid. It is soluble in water, toluene, xylene and ethanol, but insoluble in petroleum ether. Triton X-100 has a hydrophilic end and a hydrophobic end, which can dissociate membrane proteins from the cell membrane to extract membrane proteins. It is a widely used non-ionic surfactant. 1% tritonX-100 is often used to rinse tissue specimens, and 0.3% tritonX-100 is often used to dilute serum, prepare BSA, etc.
It can be used as a gas chromatography stationary liquid (the operating temperature shall not be higher than 190°C, and the solvents are acetone, chloroform, dichloromethane, and methanol) to separate and analyze hydrocarbon compounds, oxygenated compounds (alcohols, esters, ketones), alkaline and neutral compounds. Nitrogen-containing compounds, mercaptans.
