PEG/PPG-14/4 Dimethicone description

PEG/PPG-14/4 dimethicone is a derivative of the silicone dimethicone that serves as a surfactant (surface active agent) and emulsifier in cosmetics. It also functions as a skin and hair conditioning ingredient. Regarding claims that silicones in any form cause or worsen skin concerns, those have not been substantiated in any published research, nor have reports that silicones are sensitising to or somehow “suffocate” skin. In fact, just the opposite is true which makes the misinformation difficult to understand. Almost all of the claims about silicones being problematic for skin are either myths or based on anecdotal evidence. The independent Cosmetic Ingredient Review panel has found PEG/PPG-14/4 dimethicone safe as used in skin care products. Typical concentrations used in rinse-off products range from 0.1–2% while leave-on products may contain 0.3–3%.

Peer-reviewed, substantiated scientific research is used to assess ingredients in this dictionary. Regulations regarding constraints, permitted concentration levels and availability vary by country and region.
