Bis-PEG/PPG-16/16 Dimethicone
What is Bis-PEG/PPG-16/16 Dimethicone?
Bis-PEG/PPG-16/16 Dimethicone is a synthetic polymer derived from dimethicone, a type of polydimethylsiloxane, chemically modified by attaching polyethylene glycol (PEG) and polypropylene glycol (PPG) chains. This creates a hydrophilic-lipophilic structure ideal for emulsifying water into silicone phases. Primarily used in water-in-silicone emulsions found in foundations, sunscreens, moisturizers, and hair conditioners, it functions as an emulsifier, skin conditioning agent, and surfactant. It enables stable formulations with a lightweight, non-greasy texture, improves product spreadability, and enhances the delivery of active ingredients by forming protective films on skin or hair without heaviness.
Benefits
Creates silky, lightweight textures in emulsions.
Supports stable water-in-silicone formulas for even application.
