DEA-OLETH-3 PHOSPHATE.

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

DEA-OLETH-3 PHOSPHATE is a powerful emulsifier and surfactant, vital for creating stable oil-in-water formulations in cosmetics. It enables the cohesive blending of immiscible liquids, ensuring product homogeneity and enhancing texture.

Summary

Emulsifying Surfactant

Science

Mechanism of Action

This ingredient functions by significantly lowering the surface tension between oil and water phases, facilitating their stable emulsification. As an emulsifier, it stabilizes the dispersed phase, preventing separation, while its surfactant properties improve the solubility and uniform dispersion of other components within a formulation.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

DEA-OLETH-3 PHOSPHATE is a derivative of Diethanolamine (DEA), which is a restricted ingredient in Europe and banned under EC Regulation 1223/2009 due to concerns over cancer and organ toxicity, alongside potential for irritation to skin, eyes, nose, and throat. California's Proposition 65 has listed DEA as a cancer-causing agent since 2012. While the ingredient itself is deemed 'safe with restrictions' by CIR, strict adherence to formulation guidelines is critical to mitigate potential skin irritation or allergic reactions. Furthermore, there are significant concerns regarding potential contamination with impurities such as Ethylene Oxide and 1,4-Dioxane.

Our Assessment

Verdict

Avoid

Despite its functional efficacy as an emulsifier and surfactant, the presence of Diethanolamine (DEA) derivatives and associated significant safety concerns, including European regulatory bans and potential for harmful impurities, warrant avoiding DEA-OLETH-3 PHOSPHATE in precision skincare.
