  W hat I s an E mulsifier in C hemistry ? Surfactants are substances that contain hydrophilic and hydrophobic bases.   S urfactants and emulsifiers  refer to substances that have a fixed hydrophilic and oil-friendly group that can be orientated on the surface of the solution and can significantly reduce surface tension.   An emulsifier chemistry is a surfactant and can also be used as a penetrant. The surfactant has the function of emulsification, but also other functions.   The main functions of the surfactant are: stain removal, emulsification, solution, suspension, bubble elimination, sterilization and so on. There are many kinds of surfactants. According to the use classification, there are emulsifiers, antistatic agents and detergents, stabilizers, defoaming agents, dispersants, etc. These uses can be distinguished according to the size of the hlb value of wetting agent. Surfactants have a large range and contain emulsifiers. The HLB value of the surfactant is between 0-40, while

  W hat I s S ulfonate in S hampoo ? S ulfate and sulfonate free shampoo  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 sulfonate in shampoo. 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

  A nionic surfactant raw material  has a longest history, highest output and most various types. It is classified according to the structures of their hydrophilic groups: sulfonates and sulfates, which are the main types of anionic agents . The various functions of surfactants are mainly manifested in changing the properties of the liquid surface, the liquid-liquid interface and the liquid-solid interface.   Sodium Laureth(2) Sulfate (AES/SLES) Chemical Formula: C12H26Na2O5S CAS No.: 68585-34-2 Dangerous Grade: Non-dangerous Sodium Alpha Olefin Sulfonate (AOS-35) Chemical Formula: R-CH=CH-(CH2)n-SO3Na CAS No.: 68439-57-6 Dangerous Grade: Non-dangerous C12-14 Linear Alkyl Benzene Sulfonate （ LAS ） Chemical Formula:C18H30O3S CAS No.:27176-87-0 Dangerous Grade: 8   Common anionic surfactant: Sulfate, sulfonate, and phosphate esters Anionic oil soluble surfactants contain anionic functional groups at their head, such as sulfate,sulfonate, phosphate, and carboxylates.
