Uses
Different sources of media describe the Uses of 122-19-0 differently. You can refer to the following data:
1. 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.
2. Stearyldimethylbenzylammonium chloride is an anti-static that can also be used as a surfactant and/or a preservative depending on formulatory requirements.
Preparation
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.
General Description
Stearyldimethylbenzylammonium chloride is White solid or thick liquid with a mild odor.

Check Digit Verification of cas no
The CAS Registry Mumber 122-19-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122-19:
(5*1)+(4*2)+(3*2)+(2*1)+(1*9)=30
30 % 10 = 0
So 122-19-0 is a valid CAS Registry Number.

Paragraph 0042; 0043; 0048; 0049, (2017/04/03)
The invention relates to a synthetic method of aryl sulphobetaine in a solvent-free system. The method comprises the steps that alkyl dimethyl tertiary amine and benzyl chloride which are close to the stoichiometric ratio react to synthetize alkyl dimethyl benzyl ammonium chloride at a low temperature, under high-speed stirring of a planetary stirrer and dilution of dry air in the solvent-free system, alkyl dimethyl benzyl ammonium chloride is added into chlorosulfonic acid close to the stoichiometric ratio step by step for a reaction, and alkyl dimethyl benzyl sulphobetaine is obtained. According to the method, no solvent is needed, the production cost is low, a small amount of residual chlorosulfonic acid obtained after a solvent-free reaction can be recycled through high-speed centrifugation, and the yield of alkyl dimethyl benzyl sulphobetaine can reach 98% or above.
