PEG-3 DISOYOYLAMIDOETHYLMONIUM METHOSULFATE.

Questionable CAS 68605-27-6 / ANTISTATIC, HAIR CONDITIONING

PEG-3 DISOYOYLAMIDOETHYLMONIUM METHOSULFATE is a quaternary ammonium salt primarily recognized for its antistatic and conditioning properties. It functions by forming an adsorptive layer on surfaces, mitigating static charge.

Summary

antistatic hair conditioning

Science

Mechanism of Action

As a quaternary ammonium salt, PEG-3 DISOYOYLAMIDOETHYLMONIUM METHOSULFATE carries a positive charge that allows it to adsorb onto negatively charged surfaces, such as hair and skin. This interaction neutralizes static electricity and imparts a conditioning sensation.

Stability

Polyethylene glycols (PEGs) generally exhibit decreasing water solubility with increasing molar mass. As a lower molecular weight PEG (PEG-3), this ingredient is expected to be readily water-soluble. No specific pH range for optimal stability was identified in the research data.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) panel has not yet assessed PEG-3 DISOYOYLAMIDOETHYLMONIUM METHOSULFATE for safety in cosmetic applications. While EWG identifies low concern for cancer, allergies, immunotoxicity, and developmental/reproductive toxicity, it highlights significant contamination risks from Ethylene Oxide and 1,4-Dioxane, which are byproducts of PEG synthesis. Consequently, EWG VERIFIED standards restrict its inclusion without rigorous substantiation. It's important to note that the FDA's 'Generally Recognized as Safe' (GRAS) designation applies to its limited use in food or household cleaners, not for cosmetic use.

Our Assessment

Verdict

Questionable

Given the absence of a Cosmetic Ingredient Review (CIR) assessment, identified contamination concerns with Ethylene Oxide and 1,4-Dioxane, and its primary function as a hair conditioning and antistatic agent, its use in precision skincare is questionable without further rigorous safety and efficacy data.
