Physical and Chemical Properties | This product is colorless or light yellow transparent liquid, the relative density of 0.98 at 20 deg C. Soluble in water and polar organic solvents, slightly soluble in non-polar organic solvents in aqueous solution shows non-ionic or cationic characteristics. When the pH value <7 is cationic, Amine oxide itself is an excellent detergent, can produce stable and rich foam, melting point of 132~133. |
Use | It is used as a foam promoter, conditioner, thickener and antistatic agent for shampoos, liquid detergents and foam baths, and is also a raw material for the synthesis of amphoteric surfactants. |

Low irritation to the skin. It should be stored in a cool and ventilated warehouse.
Add 300kg of dimethyldodecylamine, a small amount of water, and a small amount of stabilizer into the reaction kettle. Heat up to 50-55 ℃ with stirring, and start adding hydrogen peroxide dropwise at a dosage of 55kg. After the dripping is completed, continue to heat up to 60-70 ℃ until no heat is released, cool, discharge, and fill the finished product.
