Anionic Surfactant



Anionic nonionic surfactant has a longest history, highest output and most various types. It is classified according to the structures of their hydrophilic groups: oil soluble surfactants and sulfates, which are the main types of anionic surfactants. The various functions of surfactants are mainly manifested in changing the properties of the liquid surface, the liquid-liquid interface and the liquid-solid interface.

Common anionic surfactant:

Sulfate, sulfonate, and phosphate esters

Anionic surfactants contain anionic functional groups at their head, such as sulfate,sulfonate, phosphate, and carboxylates. Prominent alkyl sulfates include ammonium lauryl sulfate, sodium lauryl sulfate (sodium dodecyl sulfate, SLS, or SDS), and the related alkyl-ether sulfates sodium laureth sulfate (sodium lauryl ether sulfate or SLES), and sodium myreth sulfate. Carboxylates are the most common surfactants and comprise the carboxylate salts (soaps), such as sodium stearate. More specialized species include sodium lauroyl sarcosinate and carboxylate-based fluorosurfactants such as perfluorononanoate, perfluorooctanoate (PFOA or PFO).



Anionic surfactants take many advantages in mature production process, great availability of raw materials, and a wide range of applications. Therefore, it is widely used in many fields such as agriculture, industrial cleaning, textile printing and dyeing, and household chemicals.



1. Agriculture

The use of anionic and non-ionic formulations as pesticide emulsifiers can reduce the usage of emulsifier from 20% ~40% to 3% ~ 10%. This will help improve the chemical stability of pesticides, while reducing costs, pollution,so ensure the efficiency of utilization. In addition, alkylbenzene sulfonates, lignosulfonates are often added into insecticides, rust removers, and plant growth regulators as emulsifiers and wetting agents to improve soil quality.



2. Construction industry

In architectural coatings, surfactants primarily act as wetting, emulsifying, dispersing, stabilizing and antistatic agent.



3. Cosmetics industry

The use of anionic surfactants in cosmetics has become more widespread in recent years and its main role is as emulsifiers, solubilizers, wetting agents and effective component synergists.



4. Oil field industry

Surfactants play an important role in the chemical oil displacement process. They can reduce the oil/water interfacial tension and increase the number of capillary tubes, thereby greatly improving the oil recovery.



5. Textile industry

Many processes in the textile printing industry require the use of a large amount of surfactants. For example, a large number of anionic surfactants with cleaning performance are used in the pretreatment process, anionic surfactants with infiltrating performance are used in the dyeing and finishing processes. In addition, some functional products such as leveling agents, fixing agents, etc., are also of anionic type.



6. Daily chemical industry

Anionic surfactants are widely used in daily chemicals. The most common application is soap. The main ingredient is sodium stearate. Anionic products have the characteristics of high foam and delicate performance, low price and so on, which can reduce the cost of the liquid detergent and other products, as well as improve the product transparency.



Now the price of anionic wetting agent is reasonable, if you have needs to buy anionic agents, please contact us.

What is GLycolic Acid?

  We like to focus on the ingredients of beauty products. But we prefer to touch the product and explore whether it really works. Alpha hydroxy acid is also known as AHA. It includes glycolic acid , lactic acid and citric acid. These products do not meet the needs.   Now we analyze the most popular ingredient in the world - glycolic acid.   Glycolic acid is a naturally occurring substance that is added to skin care products. It is good for the skin and restores skin elasticity and moisturization. The original state of glycolic acid is a powder composed of colorless crystals. It is tasteless. Let's first understand its benefits and its related products.   The Benefits of Glycolic Acid Glycolic acid is very effective for skin treatment because of its high purity. The premise is safe and correct use. Many skin care products contain glycolic acid. Sensitive muscles can also be used. Glycolic acid is non-irritating and it can be used in skin care. Add more glycolic acid to the facial cl

Acetyl Chloride

  Features of Acetyl Chloride Product Name: Acetyl chloride Chemical Formula: C2H3ClO Acetyl chloride cas : 75-36-5 Dangerous Grade: 3.2 Technical Data of Acetyl Chloride ITERMS SPECIFICATION Appearance Colourless transparent liquid Assay ≥99.0% Phosphorus content ≤0.02% Package and Storage: 200kg/drum Store in a cool, dry place. Keep container closed when not in use Application /Application Industries: Acetylation reagent Pharmaceuticals Dye Acetyl chloride is a colorless flammable liquid with a pungent odor. It is violently decomposed by water or ethanol. Dissolved in chloroform, ether, benzene, petroleum ether or glacial acetic acid. Acetyl chloride is an irritant and corrosive agent. Contact with the skin can cause burns, and steam can strongly irritate the eyes and mucous membranes. When people inhale 2 ppm, they can feel the stimulating effect. Short-term exposure to higher concentrations of acetyl chloride may cause death or permanent damage. The amount of aquatic live poisoning

Polyether Polyol Manufacturing ProcessPolyether Polyol Manufacturing Process

  Synthesis of DMC-based polyether polyol by a continuous method   A certain amount of DMC catalyst is taken and uniformly dispersed in a certain amount of small molecule initiator. Add 0.5 kg of the mixture of the initiator in the small test reactor. The vacuum was replaced 1-2 times with N2, and the N2 pressure was maintained at 0.1 MPa. After heating, stirring and raising the temperature to a certain temperature, the quantitative PO was introduced into the continuous autoclave with nitrogen gas for induction. When the induction is successful (the temperature in the kettle rises and the pressure drops), the PO is continuously passed to carry out the reaction. Open the outer loop and continue to pass the PO into the continuous kettle.   When the liquid in the reaction vessel is full, the PO, DMC catalyst and the initiator are continuously added to the kettle at a certain ratio and a certain speed through the power system. Continuous discharge is started when a certain pressure is reac
