| | Benzyldimethylstearylammonium Chloride Usage And Synthesis |
| Chemical Properties | Benzyldimethylstearylammonium Chloride is a light yellow sticky paste. It is soluble in water, acid resistant, hard water resistant, inorganic salt resistant, not alkali resistant. | | Uses | Stearyldimethylbenzylammonium chloride is a compound used in products for promoting skin cleanliness and health. It is used in hair care formulations, as a hair conditioner and cream rinse. | | Uses | Stearyldimethylbenzylammonium chloride is an anti-static that can also be used as a surfactant and/or a preservative depending on formulatory requirements. | | Preparation | Synthesis of benzyldimethylstearylammonium chloride: put 450kg of dimethyl octadecylamine into the reaction kettle, heat to 80~85℃, and slowly add 180kg of benzyl chloride under stirring in 1.5~2h. Keep warm at 80～90℃ during the drop addition. After the dosing is completed, increase the temperature to 100~105℃, hold the reaction for several hours and take samples to measure the pH value. When the pH value of 1% aqueous solution reaches 6~6.5, the reaction is completed. Cool down to 60℃ and discharge to get benzyldimethylstearylammonium chloride. | | General Description | Stearyldimethylbenzylammonium chloride is White solid or thick liquid with a mild odor. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | Acidic organic salt solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. | | Health Hazard | Ingestion causes gastrointestinal disturbances. Contact with chemical irritates eyes and skin and may damage eyes. | | Fire Hazard | Special Hazards of Combustion Products: Toxic oxides of nitrogen and hydrochloric acid fumes may form in fires. | | Flammability and Explosibility | Not classified | | Safety Profile | Poison by
intraperitoneal route. Moderately toxic by
ingestion. A human skin irritant and severe
experimental eye irritant. When heated to
decomposition it emits very toxic fumes of
NOx, NH3, and Cl-. | | Purification Methods | Crystallise the salt from acetone, EtOAc or EtOAc/ Et2O. [Sumiki et al. J Agric Chem Soc Jpn 26 325 1952, Chem Abstr 3505 1953, Beilstein 12 III 2212, 12 IV 2168.] |
