PEG-40 HYDROGENATED TALLOW AMINE.

Valuable CAS 61791-26-2 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-40 Hydrogenated Tallow Amine is a versatile ethoxylated amine, primarily functioning as a surfactant and emulsifier. It facilitates the stable blending of oil and water phases in formulations, while also contributing to cleansing, foaming, and antistatic properties.

Cleansing Agent Emulsifier Surfactant Antistatic Agent Foam Booster Viscosity Increasing Agent

Science

Mechanism of Action

This ingredient operates by significantly reducing the surface tension between disparate phases, such as oil and water, allowing them to mix and form stable emulsions. Its surfactant nature enables effective cleansing by emulsifying oils and dirt, enhances foam generation, and contributes to the even distribution of ingredients. Furthermore, it can impart antistatic benefits and assist in modulating the viscosity of liquid formulations.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEG-40 Hydrogenated Tallow Amine, along with similar PEGs cocamine ingredients, is safe for use in cosmetic formulations under current industry practices and concentrations, provided the final product is formulated to be non-irritating. While ethoxylation processes can potentially generate 1,4-dioxane, this impurity is typically removed to trace levels during purification. Concerns regarding structurally similar, unhydrogenated tallow amines (due to unsaturated fatty acid moieties) are mitigated in this hydrogenated form.
