DIETHYL ETHANOLAMINE

Description

Diethyl ethanolamine (DEEA) is an organic compound with the chemical formula (C2H5)2NCH2CH2OH. This versatile amine functions as a pH adjuster, buffering agent, and emulsifier in various skincare and cosmetic formulations. DEEA is a colorless to pale yellow liquid with a mild ammonia-like odor.

In skincare products, DEEA helps maintain optimal pH levels, crucial for product stability and skin compatibility. It acts as a weak base, neutralizing acidic components and preventing irritation. As an emulsifier, it aids in blending oil and water-based ingredients, enhancing product texture and stability.

DEEA also serves as a penetration enhancer, potentially improving the absorption of active ingredients into the skin. However, this property requires careful formulation to ensure product safety and efficacy. Some studies suggest DEEA may have mild antimicrobial properties, contributing to product preservation.

While generally considered safe in cosmetic concentrations, DEEA can cause skin irritation in sensitive individuals or at high concentrations. Formulators must adhere to regulatory guidelines and conduct thorough safety assessments when incorporating DEEA into skincare products. Its use is typically limited to leave-on and rinse-off products at concentrations below 5%.
