  What's polysorbate 65 ?   Polysorbate 65 is also known as polyoxyethylene sorbitan tristearate, dehydrated sorbitan tristearate polyoxyethylene ether, T-65 emulsifier.   Polysorbate 65 is produced in the addition reaction between sorbitan tristearate and ethylene oxide with sodium hydroxide as the catalyst.   Main applications: It can be used as emulsifier, stabilizer, wetting agent, diffusion agent, permeability agent, etc. It is mainly used as oil-in-water emulsifier for creams and lotion cosmetics, as well as thickening agent. It can be used as wetting agent, paraffin inhibitor for oil field.   Physical and Chemical Properties: CAS:9005-71-4 Apperance ： amber oily viscous liquid Density ： unknown Relative density ： unknown Melting point ： about 30 º C Boiling point ： unknown Flash point ： >120 ° C （ Closed cup ） Inflammability (solid, gas) ： unknown Vapor pressure ： <1.33hPa Vapor density ： unknown Molecular Formula ： C100H194O28 Molecular weight ： 18...

  Complexation of proteins   As an emulsifier, it can increase the affinity between food components, reduce the interfacial tension, improve the quality of food, and the processing performance of food raw materials. In bread and cake, make the protein network more closely connected, enhance the strength of the dough, inhibit the evaporation of water, increase the volume, improve the taste of food. In milk drinks, the original structure of the protein can be stretched out and combined with the hydrophobic region of the expanded protein molecule, thereby increasing the hydrophilicity of the protein and increasing its solubility. This action can improve protein stability and prevent protein aggregation and precipitation.   Effects on oils and fats   Sorbitan monostearate is a surfactant whose molecules are adsorbed at the water-oil interface to form an interfacial membrane, thereby reducing the surface tension and allowing one liquid to be dispersed in droplets in anoth...

  Sorbitan trioleate   is a light yellow viscous liquid at room temperature, almost insoluble in ethanol, ethyl acetate, petroleum ether and toluene, and insoluble in water. It gradually saponifies under strong acid or strong base conditions; stable in weak acid or weak base. Sorbitan trioleat   should be stored in an airtight container and stored in a cool and dry place.   Sorbitan trioleate is used as emulsifier, wetting agent, dispersant, stabilizer, defoamer, antistatic agent, thickener, antirust agent, etc.; widely used in food, medicine, cosmetics, textile printing and dyeing auxiliary, paint and petrochemical industries. Pharmaceutical sorbitan trioleate is an excellent non-ionic surfactant, which can be used as emulsifier, solubilizer, suspending agent, moisturizing agent, etc. It has a wide range of uses in the pharmaceutical industry. In the emulsion droplets prepared by sorbitan trioleate, 95% of the oil droplets have a particle size below 5 μ . Some fat-s...

  What is sorbitan stearate ?   Ⅰ . Introduction of sorbitan stearate in cosmetics Sorbitan monostearate is a brown waxy substance that is insoluble in water, can disperse in hot water and soluble in hot oil, fatty acids and various organic solvents. It is resistant to acid and alkaline, and has good stability against metal ions. Sorbitan monostearate is compatible with nonionic, most anionic and cationic surfactants. It has numerous properties including emulsifying, dispersing, thickening and lubricating and more.   Sorbitan stearate in skin care   is an ester mixture of sorbitan and stearic acid. It is prepared by dehydratation of sorbitol and esterisificaiton with stearic acid under alkaline catalysis. It can also be prepared by direct estificaiton of sorbitol and stearic acid at 180 - 280 ° C.     Ⅱ . Functions of sorbitan monostearate: 1. As a W/O food emulsifier, sorbitan monostearate can be used alone or in combination with polysorbate 60, polysorbat...

  Polysorbate 20 in skincare   is a yellow to orange oily liquid, which has a faint odor and a slight bitter taste. Its relative density is 1.09-1.12 (20 ° C), boiling point is unknown, flash point is >120 ℃ (closed cup), viscosity is 250-400mm2/s@25 ° C, molecular weight is 1226.48g/mol and molecular formula is C58H114O26. polysorbate 20 in skin care   contains relatively more hydrophilic groups, which allows it to be soluble in water, methanol, ethyl acetate and toluene(methylbenzene) and insoluble in mineral oil and vegetable oil. Its HLB is 16.7.   Polysorbate 20 for skin can be used as solubilizer, dispersing agent, stabilizer, antistatic agent and lubricant. It is an oil-in-water (O/W) type emulsifier that can be used as mineral oil emulsifier, cosmetic emulsifier, pharmaceutical emulsifier, dye co-solvent, foam stabilizer, photographic emulsion additives, shampoo viscosity adjusters, spinning oil in the anti-static silk synergist, fiber processing additives...

  What is Polysorbate ?   1.  Introduction of polysorbate adalah   Polysorbate is an orange-yellow or light-yellow relatively viscous liquid with a slight bitterness. Polysorbate is often used as a component of drugs. For example, it can be made into capsule preparations or ointment preparations. In addition, polysorbate can be used as an emulsifier in the industry.   2.  The use of polysorbate   Polysorbate has a wide range of uses. Polysorbate is a polyhydric alcohol type nonionic surfactant. It has significant resistance to electrolytes and strong hydrophilicity. It is widely used in liquid, semi-solid and solid preparations as O/W emulsifiers, solubilizers, wetting agents, dispersants and stabilizers.   Polysorbate is a type of excellent O/W emulsifier, high concentration of electrolyte and changes in pH have little effect on its emulsification ability. It has a good emulsification effect on vegetable oil, mineral oil, animal fat, etc. It can ...

  Wetting agent chemical   are a surfactant that makes a solid material more easily wetted by water by reducing its surface energy. Such as sulfonated oil, soap, pull powder BX, etc., can also be used soy lecithin, mercaptan, acyl hydrazine and mercaptan acetal, etc. Wetting agents used in pharmaceuticals   are increasingly being used in the ceramic industry.   For more information about non ionic emulsifier list   and sorbitan ester , please feel free to contact us!
