PEG-5 HYDROGENATED TALLOW AMINE.

Valuable CAS 61791-26-2 / SURFACTANT - EMULSIFYING

PEG-5 Hydrogenated Tallow Amine is a polyoxyethylene derivative of hydrogenated tallow amine, primarily functioning as a versatile surfactant and emulsifier in cosmetic formulations. It facilitates the stable blending of disparate ingredients like oil and water, while also offering cleansing and antistatic properties. Its complex nature provides both non-ionic and cationic characteristics, adapting to different formulation requirements.

Science

Mechanism of Action

On the skin, PEG-5 Hydrogenated Tallow Amine acts as a powerful surfactant, efficiently reducing the surface tension between various components to create stable emulsions. Its cleansing action works by encapsulating dirt and oils, allowing them to be rinsed away. The polyoxyethylene (PEG) segment of similar compounds is also recognized for its humectant properties, attracting and binding water molecules to the skin's surface, which supports skin hydration and helps to minimize transepidermal water loss.

Key findings

  1. 01 POE-5/POP-12 tallow amine (a likely analog) showed increased salivation in rats at these doses due to reduced diet palatability. No other significant toxicological effects or unscheduled deaths were observed.
  2. 02 Exposure to PEG-15 tallow amine caused statistically and toxicologically significant effects, including soft stools, decreased body weights, and reduced body weight gains.
  3. 03 No systemic toxic effects were observed in rats following dermal application of PEG-15 cocamine.

Stability

This ingredient exhibits stability under typical ambient conditions and maintains efficacy in the presence of hard water, as well as across a broad range of acidic and alkaline formulations. A 5% aqueous solution typically presents a pH between 9.0 and 10.0. Its amphiphilic nature, essential for its surfactant and emulsifying roles, suggests affinity for both oil and water phases, despite some conflicting solubility reports.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PEGs cocamine and related ingredients, including PEGs hydrogenated tallow amine, safe for use in cosmetic formulations, provided they are formulated to be non-irritating. This conclusion supersedes a prior assessment that sought additional data on impurities (e.g., nitrosamines) and genotoxicity. While generally considered safe, some individuals, especially those with sensitive or damaged skin, may experience mild to moderate irritation or allergic reactions such as redness, itching, or swelling. Prolonged or repeated exposure can lead to contact dermatitis in susceptible individuals. Data on topical usage during pregnancy or breastfeeding is limited, and professional medical advice is recommended.
