safety

Low irritation to the skin. It should be stored in a cool and ventilated warehouse.

Preparation method

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.

Reference Information

LogP	1.85 at 20℃
use	this product is mainly used for tableware detergent and industrial liquid bleach. it has the function of increasing foam and stabilizing foam, and can improve the compatibility of thickener and the overall stability of the product. It is used as a foam accelerator, conditioner, thickener and antistatic agent for shampoo, liquid detergent and foam bath, and is also a raw material for synthesizing amphoteric surfactant DDAO is a non-denaturing zwitterionic detergent of about 1 mM(CMC), which is used to dissolve protein and study protein configuration and molecular interaction. N,N-Dimethyldodecylamine N-oxide
production method	300 kg of dimethyltwelve amine, a small amount of water and a small amount of stabilizer are put into a reaction kettle, the temperature is raised to 50~55 ℃ under stirring, and hydrogen peroxide is added dropwise at a dropwise dosage of 55kg. After dropping, continue to raise the temperature to 60~70 ℃ until no heat is released, cool, discharge and fill the finished product.
