PEG-10 COCAMINE.

Valuable CAS 61791-14-8 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-10 Cocamine is a versatile ethoxylated fatty amine that functions primarily as a surfactant, assisting with cleansing, emulsification, and solubilization in various formulations. It also contributes to skin hydration by forming hydrogen bonds with water molecules, thereby supporting moisture retention.

Science

Mechanism of Action

As a polyoxyethylene glycol (PEG) derivative of cocamine, this ingredient actively lowers surface tension, enabling it to act as an effective cleansing agent, emulsifier to stabilize oil and water mixtures, and a solubilizer for otherwise immiscible components. Its molecular structure facilitates the formation of hydrogen bonds with water, drawing moisture to the skin and reducing trans-epidermal water loss. Furthermore, it possesses antistatic properties and can function as a mild anti-irritant and a neutralizing agent in cosmetic preparations.

Stability

PEG-10 Cocamine and related cocamine ingredients generally exhibit stability in alkaline conditions, making them suitable for alkaline emulsions. For optimal safety and performance, formulations must be carefully adjusted to minimize irritation. It is critical to implement rigorous purification procedures to eliminate processing impurities such as 1,4-dioxane and ethylene oxide. Considerations from related cocamines suggest potential benefits from addition to the oil phase during formulation.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel, after an initial assessment of insufficient data in 1999, concluded in a comprehensive 2018 review that PEG-10 Cocamine and related ingredients are safe for use in cosmetic formulations under current practices and concentrations, provided they are formulated to be non-irritating. However, improper formulation can lead to mild to moderate skin and ocular irritation. Significant concern exists regarding potential contamination by toxic by-products, specifically 1,4-dioxane and ethylene oxide, which necessitate stringent purification. There is also a risk of nitrosamine formation if the formulation contains nitrosating agents and primary or secondary amine impurities are present. Use in inhalable product forms carries higher respiratory concerns as indicated by safety scores.
