PEG-9 COCOATE.

Valuable CAS 61791-29-5 / SURFACTANT - EMULSIFYING

PEG-9 COCOATE is a polyethylene glycol derivative of coconut oil, functioning primarily as a multi-purpose emulsifier and surfactant. It is instrumental in creating stable formulations by homogenizing otherwise immiscible oil and water components in skincare products.

Science

Mechanism of Action

This ingredient operates by reducing the interfacial tension between aqueous and oleaginous phases, a capability attributed to its molecular structure possessing both lipophilic and hydrophilic segments. This unique characteristic allows it to stabilize emulsions, facilitating the uniform dispersion of diverse ingredients within a single cosmetic product. Beyond emulsification, it contributes to cleansing, humectancy, and skin conditioning.

Stability

PEG-9 COCOATE, as an emulsifier, is crucial for forming and maintaining stable emulsions of oil and water. Polyethylene glycols with a mean molar mass up to 600 g/mol are typically liquid; its solubility and hygroscopicity tend to decrease with increasing molar mass.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel deems PEG cocoate derivatives safe for cosmetic use when formulated to be non-irritating. However, it is specifically cautioned against use on damaged or compromised skin due to documented evidence of sensitization and nephrotoxicity observed in burn patients treated with PEG-based preparations. Manufacturers are advised to implement purification steps to minimize potential contamination from 1,4-dioxane, a known byproduct of the ethoxylation process. It is permitted for use in cosmetics within the European Union.
