Regulatory Note

Certain cyclic silicones (notably D4, D5 and D6) are restricted in the EU in leave-on and rinse-off products under REACH, and environmental scrutiny of silicones continues. Confirm the exact species present and the current restriction status for your market and format.

Supplier diligence required: Cyclic silicone restrictions apply in the EU; confirm status by market.

Sold as a cosmetic raw material for professional formulation. A published INCI name does not by itself authorise use: the buyer is responsible for confirming permitted status, maximum concentration, restrictions by product type, labelling and claim rules in every market the finished product is sold in. In India, cosmetics fall under the Drugs and Cosmetics Act 1940 and the Cosmetics Rules 2020 administered by CDSCO, with BIS standards (including IS 4707 Part 2) listing restricted substances. The EU applies Regulation (EC) No 1223/2009 and its Annexes; the United States applies the FD&C Act as amended by MoCRA; Korea, Japan and China operate their own positive lists and functional-cosmetic frameworks. Every finished product needs its own safety assessment.
