  Are sulfate and sulfonate the same thing in shampoo sulfate and sulfonate   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 ...

  What is hydroxyproline   Description L-4-Hydroxy Proline, (also referred to as Hydroxy Proline or Hydroxyproline), is an amino acid, a building block of protein, made by modifying another amino acid called Proline. It is the primary component of collagen, a fibrous protein found in the dermis of the skin that gives skin its structural support and youthful firmness. Collagen is also the major component of connective tissue, the material that provides structural report for most organs in the body. In the skin, collagen is synthesized by cells called fibroblasts. This process requires vitamin C. Hydroxyproline also plays an important role in wound healing and is a vital component of bones and teeth.   Hydroxy Proline is a major component of the protein collagen. Hydroxy Proline and proline play key roles for collagen stability. l hydroxyproline for skin   is found in few proteins other than collagen. For this reason, hydroxyproline supplement   content has been u...

  What is the difference between ionic and nonionic surfactants   Nonionic surfactant that does not generate ions in aqueous solution. Its dissolution in water is due to its strong affinity for water.   Compared with anionic surfactants, ionic non ionic   surfactants have a higher emulsifying ability and a certain resistance to hard water. It is an indispensable ingredient in detergent and emulsifier formulations. Of course, compared with anionic surfactants, non-ionic surfactants also have the disadvantages of limited cloud point, poor alkali resistance, and high price.   ionic vs non ionic   are mostly liquid and slurry, and their solubility in water decreases with increasing temperature. Non-ionic surfactants have various properties such as washing, dispersing, emulsifying, wetting, adding liquid, uniform dyeing, antiseptic, protective colloid and so on. Widely used in textile, paper, food, plastic, leather, fur, glass, petroleum, chemical fiber, medicin...

  oil soluble surfactants   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 surfactants. 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.   Common anionic surfactant: Sulfate, sulfonate, and phosphate esters Anionic surfactants contain anionic functional groups at their head, such as sulfate,sulfonate, phosphate, and carboxylates. Prominent alkyl sulfates include ammonium lauryl sulfate, sodium lauryl sulfate (sodium dodecyl sulfate, SLS, or SDS), and the related alkyl-ether sulfates sodium laureth sulfate (sodium lauryl ether sulfate or SLES), and sodium myreth sulfate. Carboxylates are the most common surfactants and comprise the carboxylate salts (soaps), such as sodium stearate. More specialized species ...
