Science
Mechanism of Action
Functioning as an amphiphilic molecule, PEG-9 SOYATE reduces the interfacial tension between oil and water phases, thereby stabilizing emulsions. Its surfactant properties facilitate cleansing and dispersion. As a humectant, it attracts and binds water molecules through hydrogen bonds, boosting skin moisture levels and potentially improving the cutaneous delivery of other active substances.

Stability
While PEG-9 SOYATE effectively blends oil and water as an emulsifier and solubilizer, it's noted that PEGs can exhibit a low pH if oxidized. Additionally, PEGs may form complexes with certain active ingredients, which can potentially reduce their bioavailability or efficacy, necessitating individual formulation testing.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that related PEG derivatives of soybean oil sterols are safe for cosmetic use. Generally, PEGs exhibit low acute and chronic toxicities, causing minimal ocular or dermal irritation on intact skin. However, application to compromised or damaged skin should be avoided. Manufacturers are advised to rigorously control impurities like ethylene oxide and 1,4-dioxane. Although the SCCS has broadly noted concerns regarding formaldehyde releasers, the topical use of PEG derivatives is typically considered safe.
