Science
Mechanism of Action
This ingredient primarily functions as an emulsifier, enabling the stable dispersion of oil and water components within cosmetic matrices. As a polyethylene glycol, it exhibits humectant properties by forming hydrogen bonds with water molecules, thereby attracting and gradually delivering moisture to the skin for prolonged hydration and reduced evaporation. Furthermore, it acts as an emollient, establishing a superficial barrier on the skin to prevent transepidermal water loss (TEWL) and maintain hydration.

Safety
Safety Profile
Specific safety assessments for PEG-13 DIPHENYLOL PROPANE are limited. However, as a general class, Polyethylene Glycols (PEGs) are derived from petrochemistry and may contain residual contaminants such as ethylene oxide (a known human carcinogen) and 1,4-dioxane (a possible human carcinogen) from the manufacturing process. PEGs are explicitly prohibited in organic cosmetic formulations. They are deemed particularly hazardous when applied to damaged or compromised skin.

Verdict
While effective as an emulsifier and hydrator, the lack of specific safety review, potential for carcinogenic contaminants, and stated risk for compromised skin make PEG-13 DIPHENYLOL PROPANE a questionable choice for precision skincare.
