PEG-200 GLYCERYL TALLOWATE.

Valuable CAS 68553-11-7 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-200 Glyceryl Tallowate is a multi-functional ingredient primarily recognized for its cleansing and emulsifying properties within various formulations. It aids in stabilizing product textures by facilitating the blend of oil and water while also offering beneficial 'refatting' properties to the skin.

Cleansing Agent Emulsifier Surfactant Humectant Skin Conditioner Defoaming Agent Lubricant Viscosity Modifier

Science

Mechanism of Action

This ingredient effectively functions as a cleansing agent and an emulsifier, enabling the removal of impurities and ensuring the stability of mixed phases. As a polyethylene glycol (PEG) derivative, it acts as a surfactant, reducing surface tension, and provides humectant properties to attract moisture. It further serves as a skin conditioner, defoaming agent, lubricant, and viscosity modifier, enhancing overall product performance and contributing to skin comfort through its noted 'refatting properties'.

Stability

PEG-200 Glyceryl Tallowate, as a clear, colorless liquid, demonstrates stability under typical conditions but requires protection from direct sunlight, open flames, and strong oxidizing agents. Elevated temperatures, light exposure, and the presence of oxygen can accelerate its aging, potentially leading to increased aldehyde and carboxylate levels, peroxide formation, heightened ionic strength, and a reduction in pH. Solutions are most stable when stored frozen and shielded from light.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has concluded that PEG ingredients, including PEG 200, are safe for use in cosmetic products. Lower molecular weight PEGs are minimally absorbed, and higher molecular weight PEGs (PEG-75 and greater) do not absorb through intact skin, exhibiting minimal irritation and no sensitizing effects. However, kidney toxicity was observed in severely burned patients treated with a PEG-based antimicrobial cream, indicating that penetration significantly increases with severe damage to both the top and underlying skin layers. Therefore, PEGs should not be applied to severely compromised skin. Manufacturers are expected to purify PEGs to eliminate potential toxic impurities such as ethylene oxide and 1,4-dioxane. Due to its petrochemical origin and the ethoxylation process that can generate 1,4-dioxane, PEGs are prohibited in organic cosmetic standards. The FDA regulates PEGs for food contact applications.
