PEG-15 COCOATE.

Insufficient Data CAS 61791-29-5 / SURFACTANT - EMULSIFYING

PEG-15 Cocoate is a polyethylene glycol ester derived from coconut fatty acids, primarily utilized in skincare formulations as a surfactant and emulsifier. Direct comprehensive data for PEG-15 Cocoate is limited, with much of its functional and safety profile extrapolated from closely related ingredients such as PEG-15 Cocoamine.

Summary

emulsifying surfactant antistatic agent

Science

Mechanism of Action

Functioning as a surfactant, PEG-15 Cocoate (or its analog, PEG-15 Cocoamine) reduces the interfacial tension between immiscible phases, thereby stabilizing oil-in-water emulsions and ensuring homogeneous product consistency. It further aids in solubilizing various ingredients within a solvent. Additionally, it may act as an antistatic agent, helping to minimize static charge buildup on both skin and hair surfaces.

Key findings

  1. 01 Clinical studies involving hair styling formulations with 1.0% PEG-15 Cocoamine and adult sunscreen formulations with 2.9% PEG-15 Cocoamine demonstrated no sensitizing, photoallergic, or other phototoxic reactions in subjects. These studies focused on the safety and non-reactivity of the related ingredient.

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEGs cocamine and related ingredients, specifically including PEG-15 Cocoamine, are safe for use in cosmetic formulations under current practices of use and concentration, provided they are formulated to be non-irritating. The highest reported concentration for leave-on dermal exposure is 3.0% in products such as body and hand sprays. A recognized concern is the potential for 1,4-dioxane contamination, a byproduct of the ethoxylation process, which mandates rigorous purification steps during manufacturing.

Verdict

Insufficient Data

While a closely related ingredient (PEG-15 Cocoamine) shows promise in safety and formulation utility, direct efficacy and comprehensive safety data for PEG-15 Cocoate itself are currently insufficient for a definitive assessment.
