Science
Mechanism of Action
This ingredient operates by significantly reducing the interfacial tension between typically immiscible oil and water phases, which is fundamental for creating and maintaining stable emulsions in cosmetic formulations. As a member of the PEG family, it also serves as a solubilizer and solvent, aiding in the dissolution of poorly soluble compounds. While its direct mechanism on skin health is not a primary function, it indirectly contributes to product efficacy by improving texture, offering mild moisturizing characteristics, and potentially enhancing the dermal penetration of co-formulated active ingredients.
