PEG-5 COCOMONIUM METHOSULFATE.

Insufficient Data CAS 68989-03-7 / ANTISTATIC

PEG-5 Cocomonium Methosulfate is a versatile quaternary ammonium compound, serving primarily as a conditioning agent and surfactant. It is recognized for its ability to enhance skin moisture retention and to effectively solubilize various cosmetic components, contributing to stable and hydrating product formulations.

Science

Mechanism of Action

This ingredient functions by forming hydrogen bonds with water molecules, thereby increasing moisture retention within the skin and reducing transepidermal water loss for sustained hydration. As a polyethylene glycol (PEG) derivative, it also acts as a penetration enhancer, optimizing the delivery of other active ingredients into the skin. In hair care, it efficiently neutralizes electrostatic charges, providing an antistatic effect.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated PEG-5 Cocomonium Methosulfate for cosmetic safety. While chemically related PEGylated oils are generally deemed safe under current use concentrations when non-irritating, and the US FDA approves PEGs as food additives, a significant concern exists regarding potential contamination. The ethoxylation process used in manufacturing can introduce toxic impurities such as ethylene oxide and 1,4-dioxane, both classified as carcinogens. The EWG indicates that products containing this ingredient can be EWG VERIFIED, provided they meet stringent contamination restrictions and are not used in inhalable forms due to respiratory concerns.

Our Assessment

Verdict

Insufficient Data

PEG-5 Cocomonium Methosulfate provides valuable conditioning and humectant benefits, yet its safety profile is limited by 'insufficient data' from CIR and ongoing concerns about potential carcinogenic impurities from its manufacturing process.
