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 cations, also known as primary alkyl sulfuric acid Salt, English abbreviated as FAS or AS.

 

It is the earliest anionic surfactant after soap. It is prepared by esterification of c12-c14 fatty alcohols generated by Hydrogenolysis of coconut oil with sulfuric acid and neutralization. It has suitable solubility, foaming and decontamination properties. It is widely used in dentifrice, shampoo, bubble bath and cosmetics. It is also an important component in the formulation of light scale, heavy scale detergents, carpet cleaners and hard surface cleaning agents, such as sodium lauryl sulfate (C12H25OSO3Na).

 

2. Secondary alkyl sulfate (Teep01). It is a secondary alkyl sulfate produced by the reaction of olefin and sulfuric acid. It is a product obtained after neutralization. The trade name is Teep01. Teep01, similar to FAS, is also a kind of surfactant agent with good performance, but its solubility and wettability are better due to structural differences. It is usually made into liquid or slurry detergent, since the powder product is easy to absorb moisture and agglomerate.

Difference Between Sodium Laureth Sulfate And Sodium Lauryl Sulfate

Sodium laureth ether sulfate  (SLS) and sodium lauryl ether sulfate (SLES) are surfactants that play a role in foaming products. It is widely believed that the foam produced by a product is its performance. The composition of SLS and SLES reduces the surface tension of water. They can also be used as dispersants to properly mix spices and body spray. SLS and SLES can also be used in a variety of personal care products such as soap, shampoo, shower gel, toothpaste and other foaming products. SLS and SLES are also added to moisturizing lotions and sunscreens because of these properties. The difference between SLS and SLES is in the manufacturing process. SLS undergo a process called ethoxylation. And then you get SLES. Why do we have this ethoxylation process? Because SLS has some mild irritation on the skin, such as dry. The manufactured SLES are more gentle and do not irritate the skin. Many manufacturers do not use SLS because it is irritating. SLES should be softer o...

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...
