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...

Polyether 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 pr...
