What Is CI 17200?
CI 17200, also known as Amaranth, is a synthetic azo dye approved for use in cosmetic products. It is a water-soluble colourant that imparts a red to burgundy hue to formulations.
In skincare, it serves a purely cosmetic function — to colour the product itself rather than to provide active skincare benefits. It does not penetrate the skin or alter skin appearance beyond the visual effect of the coloured product.
How It Works
CI 17200 is a synthetic colourant that dissolves in water-based formulations. It absorbs and reflects light at wavelengths perceived as red, giving the product its colour. The molecule itself does not interact with skin cells or biological processes.
Clinical Evidence & References
CI 17200 is a regulated cosmetic colourant with an established safety history in approved applications. There is no clinical evidence of skincare benefits because the ingredient is not designed to be active on skin — it colours the formula only. Regulatory bodies including the FDA and UK Cosmetic Products Enforcement Notices have approved its use within specified limits.
How to Use
CI 17200 appears in finished skincare products at levels determined by the manufacturer for aesthetic purposes. There is no need to adjust usage based on the presence of this ingredient. Its presence does not alter how you should use the product itself.
