PEG-25 TALLOW AMINE.

Valuable CAS - / ANTISTATIC, HAIR CONDITIONING

PEG-25 Tallow Amine is a polyoxyethylene derivative primarily functioning as an emulsifier, stabilizing oil and water phases in formulations. It also offers emollient properties, contributing to skin softening and potentially enhancing moisture retention by supporting barrier function. Beyond its emulsifying role, it acts as a surfactant, antistatic agent, and a hair conditioner.

Summary

Emulsifying Emollient Moisture Retention Surfactant Antistatic Hair Conditioning Penetration Enhancer

Science

Mechanism of Action

This ingredient operates on multiple levels within a formulation. As an emulsifier, it facilitates the homogeneous blending of immiscible liquids, crucial for stable cosmetic products. On the skin, it provides emollient effects, promoting a softer texture. Its polyoxyethylene structure enables it to attract and retain water, potentially improving skin hydration and reinforcing the natural barrier. Furthermore, it functions as a surfactant to aid cleansing, an antistatic agent, and a hair conditioning agent, while also demonstrating capabilities as a penetration enhancer for other active ingredients.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel deems PEG-25 Tallow Amine safe for cosmetic use, provided formulations ensure it is non-irritating. A key consideration for this ethoxylated compound is the potential for trace amounts of 1,4-dioxane, a byproduct that necessitates stringent purification processes. While certain polyethoxylated tallow amines (POEA) have raised toxicity concerns in pesticide contexts, this differs from cosmetic applications. The SCCS has not issued a direct opinion on PEG-25 Tallow Amine, though it has generally noted the risk of nitrosamine formation from secondary amines under specific conditions. No explicit FDA cosmetic status is available, but the broader 'PEG Tallow Amine' category is recognized as an indirect food additive.
