Mechanism of Action
Functioning primarily as a humectant, PPG-17 draws and retains moisture in the stratum corneum, thereby supporting robust skin hydration and maintaining the epidermal barrier function. Concurrently, it acts as an emollient, imparting a desirable smooth texture and supple feel to the skin. Its solvent properties are crucial for uniformly distributing active ingredients and other additives throughout a formulation, ensuring product consistency and efficacy.

Stability
PPG-17 exhibits robust thermal stability, allowing incorporation into both aqueous and oil phases; however, temperatures exceeding 80°C should be avoided to preserve its integrity. For optimal shelf life, store at ambient room temperature (25-40°C) in a tightly sealed container, protected from direct sunlight or excessive heat. Under these conditions, it maintains stability for a minimum of 2 years.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PPGs, including PPG-17, are safe for use in cosmetic products provided they are formulated to be non-irritating to the skin. The US Food and Drug Administration (FDA) also designates it as safe for general or specific limited use in food. Common cosmetic usage rates typically range from 1% to 20%, with an absolute maximum concentration recommendation not to exceed 50%.
