Science
Mechanism of Action
This ingredient functions as a surfactant, adeptly emulsifying, solubilizing, and cleansing. Its castor oil component, with a distinct fatty acid profile, can permeate the stratum corneum to help retain moisture and fortify the skin's protective barrier, mitigating transepidermal water loss. Additionally, its polyethylene glycol (PEG) units enhance long-term hydration by forming hydrogen bonds with water molecules, thereby reducing evaporation and supporting the restoration of the skin barrier, particularly beneficial for dry conditions.

Safety Profile
The CIR Expert Panel deems PEG-26 Castor Oil safe for cosmetic use, extrapolating from related PEG Castor Oils found safe at concentrations up to 50%. While considered safe when formulated to be non-irritating, potential trace amounts of 1,4-dioxane, a by-product of ethoxylation, necessitate rigorous purification controls. This ingredient aligns with general provisions of the EU Cosmetics Regulation.
