Science
Mechanism of Action
This ingredient primarily functions as a surfactant, reducing surface tension for effective cleansing. Its robust emulsifying properties are essential for creating stable, homogenous oil-in-water emulsions. Additionally, it acts as a solubilizer, dissolving active ingredients, fragrances, and colorants within cosmetic formulations. As a PEG derivative, it may impart humectant and skin conditioning properties, with the jojoba alcohol component potentially contributing emollience.
