化学的特性
Benzyldimethylstearylammonium Chloride is a light yellow sticky paste. It is soluble in water, acid resistant, hard water resistant, inorganic salt resistant, not alkali resistant.
使用
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.
製造方法
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.
一般的な説明
Stearyldimethylbenzylammonium chloride is White solid or thick liquid with a mild odor.
空気と水の反応
Insoluble in water.
反応プロフィール
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.
健康ハザード
Ingestion causes gastrointestinal disturbances. Contact with chemical irritates eyes and skin and may damage eyes.
火災危険
Special Hazards of Combustion Products: Toxic oxides of nitrogen and hydrochloric acid fumes may form in fires.
安全性プロファイル
