Benzyldimethylstearylammonium Chloride Usage And Synthesis
Chemical PropertiesBenzyldimethylstearylammonium Chloride is a light yellow sticky paste. It is soluble in water, acid resistant, hard water resistant, inorganic salt resistant, not alkali resistant.
UsesStearyldimethylbenzylammonium chloride is an anti-static that can also be used as a surfactant and/or a preservative depending on formulatory requirements.
UsesStearyldimethylbenzylammonium 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.
PreparationSynthesis 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 DescriptionStearyldimethylbenzylammonium chloride is White solid or thick liquid with a mild odor.
Air & Water ReactionsInsoluble in water.
Reactivity ProfileAcidic 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 HazardIngestion causes gastrointestinal disturbances. Contact with chemical irritates eyes and skin and may damage eyes.
Fire HazardSpecial Hazards of Combustion Products: Toxic oxides of nitrogen and hydrochloric acid fumes may form in fires.
Flammability and ExplosibilityNotclassified
Safety ProfilePoison 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 MethodsCrystallise 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.]
