What is Cyclomethicone?
Cyclomethicone is a term used for a mixture of cyclic silicones — primarily cyclopentasiloxane (D5) and cyclotetrasiloxane (D4). It is a lightweight, volatile silicone that evaporates from skin and hair after application.
Why is Cyclomethicone used in personal-care products?
Used as a carrier and texture-modifying agent that delivers other ingredients to the skin and then evaporates, leaving a smooth, dry finish without residue. Common in deodorants, hair conditioners, and foundations.
What regulators have flagged about Cyclomethicone
Cyclomethicone itself has a good short-term safety profile at cosmetic use levels. However, the EU has restricted specific cyclic silicones D4 (cyclopentasiloxane — now banned from rinse-off in EU) and D5/D6 (≤0.1% in rinse-off products) due to persistence, bioaccumulation, and potential endocrine-disrupting effects in aquatic organisms. Human health risk at cosmetic concentrations is considered low, but regulatory caution is appropriate. D5 has been studied for potential endocrine disruption in animals; evidence for human endocrine effects at cosmetic doses is not established.
