Science
Mechanism of Action
This ingredient's primary mechanism is emulsification, which enables the stable integration of disparate aqueous and oil phases within a product, ensuring consistency and uniform delivery. Furthermore, its structural similarity to PEG-8 suggests it can function as a humectant, drawing and binding moisture to the skin to enhance hydration, and act as a solvent to improve the solubilization and absorption of other cosmetic components.

The Formula
Formulation
Stability
The PEG-8 base compound is a clear, colorless liquid exhibiting stability and resistance to moderately strong acids, alkalis, and salt solutions within an optimal pH range of 4.5 to 7.5. Its role as an emulsifier is fundamental in maintaining the stability of oil and water mixtures.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated the broader class of alkyl PEG/PPG ethers, including this ingredient, concluding them safe for cosmetic use at current concentrations when formulated to be non-irritating. However, direct specific data for PEG-8 Isolaurel Thioether is limited. General concerns associated with PEGs include potential contamination with ethylene oxide and 1,4-dioxane, and it is advised not to use products containing PEGs on broken or compromised skin.
