CETYL PEG/PPG-10/1 DIMETHICONE
CETYL PEG/PPG-10/1 DIMETHICONE, also called cetyl PEG/PPG-10/1 dimethicone, is a silicone copolymer. It combines a cetyl dimethicone portion with a dimethicone derivative modified with ethylene oxide and propylene oxide units; the 10/1 numbers in the name refer to the average amounts of those units in the technical description.
CETYL PEG/PPG-10/1 DIMETHICONE: what it is
CETYL PEG/PPG-10/1 DIMETHICONE, also called cetyl PEG/PPG-10/1 dimethicone, is a silicone copolymer. It combines a cetyl dimethicone portion with a dimethicone derivative modified with ethylene oxide and propylene oxide units; the 10/1 numbers in the name refer to the average amounts of those units in the technical description.
It is not the same material as plain dimethicone. Its PEG and PPG segments make this silicone suited to the boundary between water and oil, which is why it can be useful where a texture needs unlike phases to stay evenly distributed. PubChem identifies the compound under the same name used in the ingredient listing.
CETYL PEG/PPG-10/1 DIMETHICONE: what it does in cosmetics
CETYL PEG/PPG-10/1 DIMETHICONE is chiefly used to help water and oil stay mixed in products such as emulsions. In practical terms, that can support an even texture during application and help keep the oily portion from visibly separating from the water-based portion in ordinary use.
It is also listed as a cleansing surfactant and skin-conditioning ingredient. In a rinse-off product, a cleansing surfactant helps oily residue disperse in water; as a skin-conditioning ingredient, it is intended to adjust skin feel after application. Those are formulation roles, not evidence that the isolated ingredient treats dryness, acne, dark spots, or other skin concerns.
CETYL PEG/PPG-10/1 DIMETHICONE: conditions and care
A clinical report described allergic contact dermatitis after use of a deodorant cream containing CETYL PEG/PPG-10/1 DIMETHICONE, confirmed by patch testing. This is a published case, not a measure of how often reactions occur; anyone who develops a reaction to a product should stop using it and seek professional advice.
