Bis-PEG/PPG-14/14 Dimethicone

Bis-PEG/PPG-14/14 Dimethicone is a silicone backbone capped with polyethylene glycol and polypropylene glycol chains, added to formulas to help water and silicone oils blend into one stable product. It works as an emulsifier and skin-feel conditioner rather than an active ingredient. CIR has reviewed the broader group of PEG/PPG-modified (alkoxylated) polysiloxanes this ingredient belongs to and did not flag a specific safety concern, though this exact ingredient has not been the subject of its own standalone report.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
