Application of α-olefin SulfonateApplication of α-olefin Sulfonate

AOS (α-olefin sulfonate sodium salt) has very good comprehensive properties. It has mature technology, reliable quality and good detergency. Especially in hard water, it also shows the characteristic that the pollution power is basically not reduced. AOS has good biodegradability, and has been mass-produced and used in Japan, South Korea, India, and the United States. In China, it is being developed in fields such as oil field additives, starch processing aids, acrylate emulsion polymerization, mercerizing of cotton, wool washing, textile and paper wetting agents. It is expected that in the near future, α-olefin sulfonate will become a new generation of main synthetic detergent raw materials, and is widely used in household and industrial detergents.

AOS is as gentle as AES, while LAS and AS are much more irritating than AOS. Therefore, AOS has a wide range of uses in personal care products. AOS is extremely stable under acidic conditions, and the skin of normal people is weakly acidic (pH value is about 5.5), which is suitable for using AOS as a component of personal washing products. Shampoo with AOS as the main active component has better foaming properties than K12. The foam released by AOS is plump and creamy, and it has a soapy feel during washing. Therefore, AOS can be used in personal care products such as bath lotion, hand sanitizer and facial cleanser.

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
