PEG/PPG-17/4 Dimethyl Ether

What is PEG/PPG-17/4 Dimethyl Ether?

PEG/PPG-17/4 Dimethyl Ether is a synthetic polymer formed from polyethylene glycol (PEG-17 units), polypropylene glycol (PPG-4 units), and dimethyl ether end groups. This water-dispersible ingredient belongs to the class of PEG/PPG copolymers commonly used in skincare products like moisturizers, serums, and cleansers. It functions primarily as a skin conditioning agent by forming a lightweight film on the skin's surface, which helps retain moisture and improves product spreadability. Its amphiphilic nature allows it to solubilize other ingredients, stabilize emulsions, and provide a non-greasy feel. In formulations, it contributes to better texture and absorption without heaviness, making it suitable for daily use in various personal care items.
