PEG-20 TALLATE.

Valuable CAS 61791-00-2 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-20 Tallate is a polyethylene glycol derivative primarily functioning as an emulsifier, surfactant, and cleansing agent in cosmetic formulations. It stabilizes oil and water mixtures, improves product spreadability, and enhances homogeneity, while also potentially offering humectant properties.

Summary

Emulsifying Surfactant Cleansing Humectant Penetration Enhancer

Science

Mechanism of Action

This ingredient operates as an emulsifier by facilitating the stable blending of disparate oil and water phases within cosmetic formulations. As a surfactant, it effectively reduces surface tension, thereby improving product spreadability and overall uniformity. Additionally, like other Polyethylene Glycols, PEG-20 Tallate may act as a humectant, helping the skin retain moisture, and potentially serve as a penetration enhancer, aiding in the delivery of other active compounds into the skin.

Stability

Based on similar PEG derivatives such as PEG-20 Stearate, PEG-20 Tallate is expected to exhibit robust stability across various conditions, including exposure to heat, acids, and bases. While its estimated water solubility is notably low at 0.01866 mg/L at 25 °C, its functional role as an emulsifier confirms its interaction with both aqueous and oil phases. Optimal formulation pH, based on similar compounds, ranges between 5.0 and 7.5, a range known to support enzyme stability in PEG solutions.

Conflicts

  • Should not be used on severely damaged skin due to increased potential for absorption and systemic toxicity.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed structurally similar PEG fatty acid esters, including PEG Stearates, safe for cosmetic use under current practices. General PEGs are characterized by low oral and dermal toxicity and are minimally irritating to intact human skin. However, a critical caveat exists: PEGs can be readily absorbed through severely compromised skin (e.g., in burn patients), which has been linked to systemic toxicity. Therefore, application on damaged skin is strongly contra-indicated. Manufacturers are also advised to ensure the stringent removal of impurities like 1,4-dioxane and ethylene oxide from PEG raw materials. The FDA broadly approves PEGs for various applications, including indirect food additives. No specific SCCS opinion for PEG-20 Tallate was found.
