Science
Mechanism of Action
As a synthetic ester derived from the esterification of polypropylene glycol with 2,2-dimethylpropanoic acid, PPG-3 Dipivalate exerts its effects by forming a protective layer on the skin's surface. This mechanism helps to minimize trans-epidermal water loss, deeply hydrate the skin, and impart a visibly smoother and more supple feel.

The Formula
Formulation
Stability
While general polypropylene glycols are typically water-soluble, PPG-3 Dipivalate is an ester, which renders it oil-soluble or miscible with oils. This characteristic makes it well-suited for a variety of anhydrous and emulsion-based formulations, maintaining good stability across a broad range of cosmetic applications.
Safety
Safety Profile
The CIR Expert Panel has determined that Polypropylene Glycols (PPGs) with a molecular weight equal to or greater than 3, including PPG-3, are safe for use in cosmetic formulations when they are formulated to be non-irritating. A maximum concentration of 50% has been assessed as safe for cosmetic applications. Furthermore, PPG-3 Dipivalate is listed as an inactive ingredient in an FDA-approved sunscreen product. Instances of adverse reactions such as skin irritation, allergic responses, redness, or itching are considered generally uncommon.
