Do You Know about Sodium Dodecyl Sulfate?

 Sodium dodecyl sulfate is a white to yellowish powder with a special slight smell. It is easily soluble in water, slightly soluble in ethanol, and almost insoluble in chloroform, ether and light petroleum. In addition, it is stable to acid, alkali and hard water. Nanjing Chemical Material Corp. has a lot of experience in the chemical area, we will then introduce you its purposes, which are listed below:

 

[Purpose 1]

It is not only used as detergent and textile auxiliaries, but also as toothpaste foaming agents, mine fire extinguishing agents, emulsion polymerization emulsifiers, wool detergent and so on.

 

[Purpose 2]

It can be used as anionic surface active agents, emulsifier and foaming agent.

 

[Purpose 3]

Sodium dodecyl sulfate can be used as processing aid, foaming agent, emulsifier and anionic surfactant in food industry. It is used for making cake, beverage, protein, fresh fruit, juice beverage, edible oil, etc.

 

[Purpose 4]

It is used as emulsifier of medicine, cosmetics and synthetic resin. It also acts as a foaming agent for toothpaste and fire extinguisher. What's more, it is used as detergent for silk and wool fine fabrics. And it is also a flotation agent for metal processing.

 

[Purpose 5]

It is used as washing and textile auxiliary, as well as toothpaste foaming agent, fire extinguishing foam liquid, emulsion polymerization emulsifier, medical emulsifying and dispersing agent, shampoo and other cosmetic products, and wool detergent.

 

[Purpose 6]

It can be used for biochemical analysis, electrophoresis, and can also be used as an ion pair reagent.

 

Sodium dodecyl sulfate is a surfactant. If you have sensitive skin, you should use sodium dodecyl sulfate with care. The concentration of sodium lauryl sulfate in the product and whether the product contains supplementary oil determines whether it will irritate the skin. If the skin feels tight after cleaning, the product may irritate the skin.

 

Nanjing Chemical Material Corporation. (NCMC), is a professional chemical distributor company which is set up through the restructuring of state-owned Nanjing Chemical Raw Material Head Company. We provide Textile and Leather, Pharmaceuticals, glycolic acid and so on. Want to know more? Please contact us.

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...

What is Polyether Polyol

  Polyether polyol is prepared by ring-opening polymerization of epoxide monomers (such as ethylene oxide, propylene oxide and 1,2-epoxybutane) and a compound containing two or more active hydrogen atoms (called an initiator). In the presence of alkali catalyst, active hydrogen compounds initiate ring opening and oxide addition will continue until the required molecular weight is obtained. The number of hydroxyl groups in polyether polyol is determined by the number of unstable hydrogen atoms in the initiator. If the initiator has two active hydrogen, glycol will be formed. The reactivity of polyether polyol  to isocyanates depends on the initiator and the type of epoxy monomer that ends the ring-opening polymerization. The primary hydroxyl produced by polyol capped with ethylene oxide is more reactive than the secondary hydroxyl produced by propylene oxide, which is ideal for applications requiring rapid curing time. However, the use of initiator based on ethylene oxide and a...

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...
