Science
Mechanism of Action
Often incorporated into a dimethicone-based complex like Bis-PEG/PPG-16/16 PEG/PPG-16/16 Dimethicone, PPG-16 functions to maintain skin health by imparting a soft, smooth feel. It forms a protective barrier on the skin, which aids in retaining moisture and minimizing transepidermal water loss. As an emulsifier, it stabilizes oil-in-water mixtures, promoting uniform consistency and reducing the greasiness of a product.

Stability
This ingredient maintains stability within a pH range of 3.5 to 7.0. While heat-tolerant, temperatures exceeding 80°C should be avoided during formulation.
Safety
Safety Profile
The CIR Expert Panel has determined that polypropylene glycols (PPGs) with a molecular weight of 3 or greater, including PPG-16, are safe for cosmetic use when formulated to prevent irritation. A safety assessment confirmed no consumer risk at a 5.0% concentration of its dimethicone complex. Dimethicone-based compounds are generally considered non-comedogenic. The FDA acknowledges PEG, a related compound, as a food additive and lists the complex 'Bis-PEG/PPG-16/16 PEG/PPG-16/16 dimethicone' in numerous leave-on and rinse-off cosmetic products.
