PEG-3 DISTEAROYLAMIDOETHYLMONIUM METHOSULFATE.

Avoid / ANTISTATIC, HAIR CONDITIONING

PEG-3 DISTEAROYLAMIDOETHYLMONIUM METHOSULFATE is a quaternary ammonium salt primarily utilized for its antistatic and hair conditioning properties. While related PEG derivatives may contribute to emulsification, this specific compound's documented functions are centered on managing electrostatic charges.

Antistatic Hair Conditioning

Science

Mechanism of Action

Operating as a quaternary ammonium salt, PEG-3 DISTEAROYLAMIDOETHYLMONIUM METHOSULFATE effectively neutralizes electrostatic charges, most notably on hair fibers, contributing to its antistatic and conditioning properties. Broader observations of PEG derivatives indicate their potential to facilitate the mixing of water with oil and dirt, aiding in rinsing, and to function as emulsifiers and solubilizers for other cosmetic ingredients. However, its direct mechanism and benefits on skin are not specifically detailed in the provided research, with its primary function attributed to hair applications.

Stability

A structurally similar compound, PEG-3 Distearate, exhibits a relatively low melting point, ranging from 44-51 degrees Celsius. This suggests that PEG-3 DISTEAROYLAMIDOETHYLMONIUM METHOSULFATE may also possess limited temperature resistance, which is a critical consideration for maintaining product stability during formulation and storage.

Not reviewed
Sensitization risk High

The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated PEG-3 DISTEAROYLAMIDOETHYLMONIUM METHOSULFATE, despite reviewing a broader class of PEG diesters. There is a notable likelihood of skin irritation, which may intensify when formulated with other potentially problematic ingredients, leading to inflammation or dryness. Furthermore, this ingredient carries a significant concern for contamination with toxic impurities, specifically ethylene oxide and 1,4-dioxane. EWG also restricts products containing this ingredient for 'EWG VERIFIED' status, requiring adequate substantiation.
