Chemische Eigenschaften
Benzyldimethylstearylammonium Chloride is a light yellow sticky paste. It is soluble in water, acid resistant, hard water resistant, inorganic salt resistant, not alkali resistant.
Verwenden
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.
synthetische
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.
Allgemeine Beschreibung
Stearyldimethylbenzylammonium chloride is White solid or thick liquid with a mild odor.
Air & Water Reaktionen
Insoluble in water.
Reaktivit?t anzeigen
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.
Brandgefahr
Special Hazards of Combustion Products: Toxic oxides of nitrogen and hydrochloric acid fumes may form in fires.
Sicherheitsprofil
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-.
l?uterung methode
