CI 61570: what it is

CI 61570 is a green colourant also known as Acid Green 25. It is an anthraquinone substance used to introduce colour into a cosmetic preparation, so its name may appear in an ingredient list even though it does not describe the product's texture or fragrance.

The CI number is an identifier used for colour materials. Acid Green 25 is one of the names used for the same substance in chemical databases, while CI 61570 is the designation that helps identify this particular colourant in ingredient lists.

CI 61570: what it does in cosmetics

CI 61570 is used to give a formula a green shade. In makeup, soaps, bath products, or other coloured cosmetics, a colourant can contribute to the visual appearance seen in the package or in the product during use.

Its purpose is colour, not treatment of skin or hair. Seeing CI 61570 on its own in an ingredient list does not indicate moisturising, antioxidant, brightening, or another care benefit; those characteristics depend on the other ingredients and on the product itself.
