Canthaxanthin
Canthaxanthin is known mainly as the natural pigment of the orange-yellow Chanterelle mushroom, but also occurs in various lower animals, some crustaceans, insects, fishes and birds. Besides its pigmentation properties, Canthaxanthin has various physiological functions and can be converted into vitamin A in case of deficiency.

| World Health Organization (WHO) |
Canthaxanthin, a naturally-occurring carotenoid with a deep redorange colour, is widely used as a food colouring agent. Since the mid-1970s it has been included in oral 'artificial suntan' preparations. It is also available in preparations used in the treatment of certain photodermatoses. By the mid-1980s its use in such preparations had been associated with the accumulation of crystalline deposits in the retina. Reported functional changes relating to dark adaptation have been of marginal clinical significance and largely reversible. Nevertheless, this has led to the withdrawal of artificial suntan preparations containing canthaxanthin by several regulatory authorities. Preparations for treatment of photodermatoses remain available in some but not all of these countries. |
