| Physical and Chemical Properties | white waxy solid. Molecular weight 364.10. Soluble in water, ethanol. It dissociates into cationic active groups in water and has good emulsifying effect. In water on mineral oil, animal and vegetable oils, synthetic oils and fats can be very good emulsification, and not affected by pH value. Acid resistance, alkali resistance and heat resistance are excellent. Active “60%,PH (1% aqueous solution)” 6.5. |
| Use | Cationic surfactants. Mainly used as cosmetics fungicides, softeners, emulsifiers and antistatic agents. When used in hair conditioner, it can be adsorbed on the surface of the hair to form a single molecular film, so that the hair is bulky, soft and gives the hair a natural luster. At the same time, it can also inhibit the static electricity generated by the friction on the surface of the hair, make the hair easy to comb. |

| properties | decasix alkyl trimethyl ammonium bromide is white or light yellow crystals to powder, soluble in isopropanol, soluble in water, A large amount of foam is generated when shaking, which has good compatibility with cationic, non-ionic and amphoteric surfactants. With excellent penetration, softening, emulsification, antistatic, biodegradability and sterilization properties. This product has good chemical stability, heat resistance, light resistance, pressure resistance, strong acid and alkali resistance. |
| pharmacology | the main component of cetrimonium bromide is carbomer, which is a chain connection composed of water-filled polymers, adhesion of the skeleton. This polymer has a unique thixotropy: that is, its structure is destroyed under the action of external force, resulting in a decrease in viscosity; After rest, its bound gel skeleton will be reconstructed, and the gel will return to the original viscosity. |
| Application | has excellent penetration, softening, emulsifying, antistatic, biodegradable and bactericidal properties. Chemical stability, heat-resistant, light-resistant, pressure-resistant, resistant to strong acid and alkali. Used as natural, synthetic rubber, silicone oil and asphalt emulsifier; Synthetic fiber, natural fiber and glass fiber antistatic agent, softener; Conditioner. used as hair conditioner, softener, bactericide, emulsifier, flocculant, etc. This product is a cationic surfactant. Can be used as a disinfectant, the preparation of gargle, disinfectant, intestinal grape absorption inhibitor. It can also be used as a micelle solubilization spectrophotometric determination reagent. for organic synthesis, can also be used as cationic surfactant, used as bactericide, preparation of gargle, disinfectant, intestinal glucose absorption inhibitor. The product is also commonly used micellar solubilization spectrophotometric reagent. used as intestinal glucose absorption inhibitor, surfactant cationic surfactant. Mainly used as cosmetics fungicides, softeners, emulsifiers and antistatic agents. When used in hair conditioner, it can be adsorbed on the surface of the hair to form a single molecular film, so that the hair is bulky, soft and gives the hair a natural luster. At the same time, it can also inhibit the static electricity generated by the friction on the surface of the hair, make the hair easy to comb. colorimetric or Photometric Determination of antimony and tin; Inhibitors of glucose absorption in the intestine; Phase transfer catalysts for the reduction of aromatic hydrocarbons and epoxidation of olefins; Surfactants; Disinfectants |
| production method | a quaternary ammonium salt is formed from the bromination of bromine with trimethylamine. The trimethylamine aqueous solution is put into the vaporization kettle, heated to boiling, the generated trimethylamine gas is dried and absorbed with acetone, and the trimethylamine acetone solution is generated in the absorption tower, this was entered into the quaternization kettle. Bromodecane was then added dropwise with stirring in a molar ratio of 1.10: 1. During the dropwise addition, the temperature was maintained at 30-40 ℃, and the mixture was stirred for 1 h after dropping. The crystals were cooled to give a crude product, which was washed with acetone, spin dried and dried to give a product. |
