91995-81-2 – Introduction

Dipalmitate carboxyethyl Hydroxyethyl methyl sulfate ammonium salt (also known as plant-based) is a surfactant whose chemical structure contains palmitic acid and ethoxy groups.

This substance has a strong surface active ability, can be used as emulsifier, thickener, dispersant and antistatic agent. Widely used in cosmetics, household cleaners, dyes, coatings and paper manufacturing industries.

The preparation method of ammonium salt of double palm carboxyethyl Hydroxyethyl methyl sulfate includes obtaining palmitoyl ethoxyethanol by esterification reaction of palmitic acid and ethoxyethanol, and then carrying out sulfation with formic acid, the final product is obtained by The ammonification reaction.

During use, it is necessary to note that the substance may be irritating to the skin and eyes, and contact with the skin and eyes should be avoided. At the same time, it should be stored in a dry, cool place, and away from fire and oxidizing agents. When disposing of waste, it is necessary to comply with relevant environmental protection regulations.
