Application 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.

Difference Between Sulfate And Sulfonate In Shampoo

Sulfates and sulfonates have two things in common. First, they're all anionic surfactants. Second, they are often used for personal care applications. But there are many differences. They have different molecular mechanisms. They have different functions and they have different raw materials. Sulfates Sulfate is a compound. It has carbon bonds and oxygen and sulfur bonds. They include substances such as sodium lauryl sulfate and sodium lauryl ether sulfate. At low pH, these substances plus the c-o-s bond hydrolyze to produce alcohol and inorganic sulfate. At a high pH, sulfate is stable in the base and, if ethoxylated to a relatively high level, produces a low-foaming alkali-soluble surfactant. Sulphates can be prepared by reaction of fatty alcohol or fatty alcohol ethoxylates with reagents such as SO3 or chlorosulfonic acid (CSA). The reason shampoo becomes thick foam in the shower is that it contains sulfate. Most shampoos and household cleansers contain su...

Two Different Types of Anionic Surfactants

Anionic surfactant is a kind of product with the longest history, the largest output and the most varieties among surfactants. According to the structure of hydrophilic groups, anionic surfactants can be divided into sulfonates and sulfates, which are the main categories of anionic surfactants. The anionic surfactants definition is a must-known concept for many people working in the chemical industry. The various functions of surfactants are mainly manifested in changing the properties of the liquid surface, liquid-liquid interface and liquid-solid interface, of which the surface (interface) of the liquid is the most important. Sulfate-type anionic surfactants mainly include fatty alcohol sulfate (also known as primary alkyl sulfate) and secondary alkyl sulfate ： 1. Fatty alcohol sulfate (ester) salt (FAS or AS). The general formula of fatty alcohol sulfate is: ROS0-3M+, R is alkyl, M+ is sodium, potassium, ammonium, ethanolamine and other ca...

The Application of Glycolic Acid in the Cosmetics Industry

In the salon, the beautician first cleans and rinses the skin area to be treated, and then applies the glycolic acid solution or gel with fingertips or cotton tips or brushes. When treating the face, leave the solution / gel in place for 5-10 minutes, then rinse off with gauze dipped in cold water. Occasionally, use the solution / gel a second time and leave it in place for 5-10 minutes before rinsing. Hand, foot and other body parts are treated similarly. According to industry sources, products applied to body parts other than the face are usually washed off after about 15 minutes. The end of the treatment is to apply moisturizing cream, which usually contains a sun protection factor (SPF) of 15. A typical course of treatment includes 6-10 peels over 4-6 weeks. When using at home, lotions, gels, lotions and creams are applied once or twice daily with fingertips or small cotton balls. Scrubs, that is, lotions or creams containing polished particles, rub the skin wit...
