Perfluorononyl Dimethicone
What Perfluorononyl Dimethicone is & what it does
Perfluorononyl Dimethicone is a fluorinated silicone derivative, a dimethicone backbone modified with a perfluorinated alkyl group. In skincare and sunscreen formulas it works as a skin-conditioning agent and film former, helping spread the product smoothly and improving water and sebum resistance. A notable property is that the fluorinated chain makes the resulting film both oil-repellent and water-repellent, which can support long-wear and transfer resistance.
Is Perfluorononyl Dimethicone safe?
Perfluorononyl Dimethicone is widely used as a film former and skin-conditioning agent in cosmetics and is generally regarded as well tolerated for topical use. As with any ingredient, individual sensitivity can vary, so patch testing a new product is reasonable if your skin reacts easily. We are not able to give medical advice, so check with a professional for specific concerns.
Is Perfluorononyl Dimethicone natural or synthetic?
It is synthetic. It is a fluorinated silicone, a dimethicone backbone modified with a perfluorinated alkyl group, and is manufactured rather than sourced directly from a plant or animal.
Does Perfluorononyl Dimethicone clog pores?
There is no strong, widely cited evidence that Perfluorononyl Dimethicone is notably pore-clogging, and silicone-based film formers are often chosen for their light, non-occlusive feel. Pore-clogging response is individual, so if you are acne-prone you may want to monitor how your skin reacts.
