DEA-OLETH-5 PHOSPHATE.

Optional CAS 58855-63-3 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A multifunctional phosphate ester that serves as a sophisticated emulsifier and surfactant in high-performance cosmetic textures. It is engineered to bridge the gap between oil and water phases while facilitating the even distribution of active ingredients across the skin surface.

Surfactant Emulsifier Solubilizer Dispersing Agent Cleansing Agent

Science

This ingredient functions by reducing interfacial tension between immiscible phases, allowing for the creation of stable emulsions. As a polar molecule, it aligns itself at the oil-water interface to prevent droplet coalescence and, when used in cleansing systems, assists in the solubilization and removal of lipophilic impurities from the skin and hair.

Stability

Demonstrates excellent stability across various pH ranges in specific applications like hair dyes, though its parent compound, Oleth-5, may be susceptible to hydrolysis in highly alkaline environments.


Safety

CIR Status
Safe as used
Sensitization risk Moderate

The CIR Expert Panel considers it safe when formulated to be non-irritating, though it should be avoided on compromised or damaged skin. While historical NTP studies on DEA-related compounds raised animal-based concerns, no human carcinogenic risk has been established, and current industry usage is declining.
