Pricing Update: Please note that due to significant global pressure on silicone availability, the price of Cyclomethicone has increased by around 20%. This has forced us to increase pricing, as we have been selling as a loss for the last 3 months. We will keep pricing under review, but costs are unlikely to return to previous levels for quite some time. Cyclomethicone is a clear, odourless cosmetic-grade silicone. It is non-greasy and evaporates quickly, making it ideal for use as a base in room and linen mists, as well as in cosmetic products. Try using 5% fragrance oil in cyclomethicone as a room mist.
