hexadecyltrimethylammonium stearate - Introduction
hexadecyltrimethylammonium stearate is a surfactant with the chemical formula C19H42N (CH3)3(CH2)16COO-. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: hexadecyltrimethylammonium stearate is a white or off-white solid.
-Solubility: Soluble in water, alcohols and organic solvents.
- pH value: generally between 4-8.
-Agglomerability: hexadecyltrimethylammonium stearate has a positive charge, so it can form a micelle structure in solution.
Use:
-Surfactant: hexadecyltrimethylammonium stearate can be used as an anionic surfactant, widely used in personal care products, detergents and other fields.
-Emulsifier: hexadecyltrimethylammonium stearate has good emulsifying properties and can be used for the preparation of emulsions.
-ion exchanger: hexadecyltrimethylammonium stearate can be used as a surfactant for cation exchange resins.
Preparation Method:
The preparation method of hexadecyltrimethylammonium stearate usually involves a three-step reaction:
1. Through the reaction of N,N-dimethylhydrazine and alcohol to obtain N,N-dimethylhydrazine salt;
2. Reacting N,N-dimethylhydrazine salt with hexadecane bromide to produce hexadecyltrimethylammonium bromide;
3. hexadecyltrimethylammonium bromide reacts with stearic acid to obtain hexadecyltrimethylammonium stearate.
Safety Information:
hexadecyltrimethylammonium stearate is relatively safe under general conditions of use, but the following matters still need to be paid attention:
-Avoid contact with skin and eyes. In case of contact, rinse with water immediately.
-Avoid inhaling the vapor of its powder or solution. If inhaled in excess, fresh air should be provided in time.
-Avoid high temperature, fire and direct sunlight during storage.
Please note that the above information is for reference only. Professional operating guidelines and safety regulations should be followed when using hexadecyltrimethylammonium stearate.
