DIETHYL ETHANOLAMINE.

Avoid CAS 100-37-8 / BUFFERING

Diethyl Ethanolamine (DEEA) is a chemical compound employed in formulations primarily to regulate and maintain pH levels. It also functions as an emulsifying agent to blend product components.

Summary

pH Adjuster Emulsifying Viscosity Controlling

Science

Mechanism of Action

DEEA effectively adjusts and stabilizes the pH of cosmetic products, ensuring formula integrity. Additionally, it acts as an emulsifier by reducing the surface tension of water, facilitating the uniform dispersion of immiscible substances.
