Science
Mechanism of Action
This ingredient effectively reduces the surface tension between immiscible liquids, thereby facilitating the formation and stability of oil-in-water emulsions. As a surfactant, it enables water to effectively mix with and remove oily impurities and dirt from the skin. It also acts as a solubilizer, allowing typically insoluble oil-based components to disperse within water-based formulations. Furthermore, it contributes to skin's soft and smooth appearance through its emollient properties and enhances hydration by functioning as a humectant.

Stability
A related compound, PEG-75 Lanolin, demonstrates stability across a pH range of 2-10, showing only slight susceptibility to oxidative and reducing agents. It forms crystal clear solutions in water and aqueous ethanol up to 40%. Similar stability characteristics can generally be anticipated for PEG-75 Sorbitan Laurate.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEG-75 Sorbitan Laurate is safe for use in cosmetic formulations at concentrations up to 25%, with the critical restriction that it should not be applied to damaged skin. Trace amounts of 1,4-dioxane, a by-product of ethoxylation, may be present, but this can be controlled and minimized through rigorous purification processes.
