What does PEG/PPG-20/15 Dimethicone do in skincare?
PEG/PPG-20/15 Dimethicone is a silicone-based surfactant and emulsifier. In skincare and sunscreen formulas it helps mix oil, water, and silicone phases and can give products a smooth, silky feel. It works as a formulation aid rather than an active ingredient.
Is PEG/PPG-20/15 Dimethicone safe?
This ingredient is widely used in cosmetics as an emulsifier and is generally regarded as well tolerated at the levels used in products. As with any ingredient, individual sensitivities can occur. If you have specific concerns, it is best to consult a qualified professional.
Does PEG/PPG-20/15 Dimethicone clog pores?
Silicone-based emulsifiers like this one are generally not considered strongly pore-clogging, and they are used in many lightweight formulas. How any product affects your skin still depends on the full formula and your individual skin type. Patch testing a new product can help you judge personal tolerance.
