Science
Mechanism of Action
This ingredient functions by significantly lowering the interfacial tension between diverse components, enabling a stable blend of oil and water phases. As an emulsifier, it stabilizes products, preventing phase separation, while its dispersing action ensures uniform distribution of solid particles, such as mineral UV filters or pigments, throughout the formulation. These properties also contribute to its efficacy in cleansing and foam generation.

Stability
Although specific optimal pH ranges for SODIUM OLETH-8 PHOSPHATE are not explicitly detailed, closely related ingredients such as SODIUM DIOLETH-8 PHOSPHATE exhibit robust emulsifying, solubilizing, and dispersing capabilities across a wide pH spectrum. Temperature and pH are critical parameters known to influence the stability of various phosphate derivatives.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a specific assessment for SODIUM OLETH-8 PHOSPHATE. However, a broader review of 28 alkyl phosphates, which includes structurally similar oleyl phosphates, concluded safety for cosmetic use when formulated to be non-irritating. Notably, the EWG Skin Deep database indicates 'high contamination concerns' regarding ethylene oxide and 1,4-dioxane for 'Sodium Dioleth 8 Phosphate,' identified as a synonym or closely related ingredient. No specific SCCS opinion or relevant FDA concerns pertinent to its cosmetic application were found.

Verdict
Despite its functional utility as a versatile surfactant, the absence of a specific safety assessment by the CIR Expert Panel for SODIUM OLETH-8 PHOSPHATE and documented high contamination concerns for a closely related ingredient by EWG warrant significant caution and further investigation for precision skincare applications.
