Science
Mechanism of Action
Functioning primarily as a binding agent, this copolymer ensures the structural integrity of powdered cosmetic formulations. Its Propylene Glycol Laurate component acts as an emollient, forming a lightweight, non-greasy film on the skin to deeply hydrate, soften, and smooth. Additionally, it stabilizes oil-in-water emulsions and facilitates the dissolution of oil-soluble compounds. Propylene Glycol within the structure acts as a skin conditioning agent, humectant, and solvent. The citric acid moiety, when active, can contribute to exfoliation by assisting in the removal of dead skin cells, potentially increasing viable epidermal thickness and dermal glycosaminoglycan content for a refined skin texture.

Stability
While Propylene Glycol Laurate exhibits a neutral pH, the citric acid-modified polypropylene glycol components, when utilized as emulsifiers, contribute to emulsion stability primarily within a pH range of approximately 8.0 to 8.9.
Safety
Safety Profile
The CIR Expert Panel has determined Propylene Glycol monoesters and diesters, including Propylene Glycol Laurate, to be safe for cosmetic application. Propylene Glycol itself is generally considered nontoxic and noncarcinogenic. Animal studies indicate Propylene Glycol Laurate caused only slight skin irritation in rabbits, while related esters like Propylene Glycol Dicaprylate/Dicaprate showed minimal to no irritation and were non-comedogenic. Citric acid and related forms are also assessed as safe. It is noted that some Propylene Glycol esters may enhance the skin penetration of other chemicals.
