anionic surfactant

shampoo, body wash bath gel

oil-displacing agent, foam boost agent for increasing oil recovery

 

Washing powders

Based on detergency test result, both LAS and AOS showed good synergy in phosphorus-containing and non-phosphorus powders. In phosphate-free washing powders with LAS and AOS as anionic active ingredients, the detergency of AOS is significantly increased when the active content is more than 20%. The detergency synergy of AOS in non-phosphorus washing powder is more oustanding than that in phosphorus-containing powder. AOS has a good compatibility with enzyme. The detergency power of AOS and LAS is not much different at high temperatures and long-term washing (eg above 60°C, washing for 1 hour). However, AOS shows higher detergency performance than LAS when used under room temperature (10-40°C for 10-29 minutes). Compared with LAS, AOS features stronger hard water resistance. AOS shows a very good stain removal performance on sebum dirt and oily and powdery stain.

 

Application of soap

Adding AOS can increase the solubility of soap in water, wetting power and foam strength of soap at low temperatures can also be increased significantly It improves various properties of the soap, enhances foaming power, increases hard water resistance and flexibility.

 

Liquid detergent application

Due to the greater irritation of LAS, many detergents do not use LAS as an active ingredient, while AOS has a low irritative property and good biodegradability, making it a more suitable alternative.

 

Personal care application

The mildness of AOS is comparable to that of AES, while LAS and AES are much more irritating than AOS. Thus AOS has a wide range of use in personal care products. AOS is extremely stable under acidic conditions, and normal human skin is weakly acidic (pH about 5.5), so it is suitable to use AOS as a component of personal washing products. Shampoos with AOS as the main active ingredient are more foamable than with K12.

 

Other applications

AOS has a wide range of applications in the textile printing and dyeing industry, petrochemicals, tertiary oil recovery, and industrial cleaning. It can also be used as a concrete density improver, foam wallboard, fire-fighting foaming agent. It can also be used as an emulsifier, wetting agent, etc.

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...
