PEG-8 TALLATE.

Valuable CAS 61791-00-2 / SURFACTANT - EMULSIFYING

PEG-8 TALLATE is a polyethylene glycol derivative primarily functioning as a versatile surfactant and emulsifier, enabling the stable co-existence of oil and water phases in cosmetic formulations. It also contributes humectant properties, drawing moisture to the skin, and acts as a solvent to optimize the absorption of other active ingredients.

Science

Mechanism of Action

As a surfactant, PEG-8 TALLATE reduces the surface tension between immiscible liquids, facilitating the formation of stable emulsions. Its emulsifying action is crucial for blending oil- and water-based components effectively. Additionally, its PEG structure imparts humectant capabilities, binding atmospheric moisture to the stratum corneum, thereby enhancing skin hydration. It further functions as a solvent, improving the dispersion and penetration efficiency of other lipophilic and hydrophilic compounds within a formulation.

Stability

Polyethylene glycols and their derivatives, including PEG-8 TALLATE, are valued in cosmetic products for their wide range of viscosity and solubility profiles, alongside general skin tolerance. Optimal stability for PEG-8 based compounds is typically observed within a pH range of 4.5-7.5.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has determined PEG-8 TALLATE, like other PEG derivatives, to be safe for cosmetic use. While historical concerns regarding their use on compromised skin were addressed and removed in a 2010 re-review, some expert sources continue to advise caution on broken or irritated skin due to the potential for trace contaminants such as ethylene oxide and 1,4-dioxane from the manufacturing process. The FDA generally recognizes polyethylene glycol (PEG) as safe.
