OLETH-2 PHOSPHATE.

Questionable CAS 39464-69-2 / SURFACTANT - EMULSIFYING

OLETH-2 PHOSPHATE is a polyethylene glycol ether of oleyl alcohol, primarily utilized as a versatile emulsifier and surfactant in cosmetic formulations. It promotes the stable blending of oil and water phases, enhancing product texture and facilitating ingredient absorption. It also acts as a dispersing and cleansing agent.

Science

Mechanism of Action

This ingredient functions by reducing the surface tension between immiscible liquids, thereby stabilizing oil-in-water or water-in-oil emulsions to create homogeneous cosmetic products. Its surfactant properties also aid in solubilizing oils and dirt, enabling effective cleansing and rinse-off from skin and hair. Furthermore, it acts as a dispersing agent for solid particles within formulations, ensuring uniform distribution.

  • Must not be applied to damaged skin, as it may increase the penetration and systemic exposure of other ingredients within the formulation.
  • Requires stringent purification to minimize potential contamination from toxic impurities like 1,4-dioxane.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The CIR Expert Panel considers the broader category of Oleth ingredients safe for current uses when carefully formulated to be non-irritating. However, OLETH-2 PHOSPHATE specifically carries a crucial restriction: it should not be used on compromised or damaged skin due to its potential to enhance ingredient penetration. Additionally, concerns regarding 1,4-dioxane contamination necessitate thorough purification steps, and products seeking EWG VERIFIED status require adequate substantiation to include this ingredient.

Verdict

Questionable

While OLETH-2 PHOSPHATE is a functional emulsifier and surfactant for various cosmetic applications, its restricted use on damaged skin and persistent concerns regarding 1,4-dioxane contamination make its inclusion questionable without rigorous formulation and purification protocols.
