| Hazard Information | Back Directory | [Chemical Properties]
Red to purple-red crystals or crystalline powder. Industrial products are stable yellow to orange oil or organic solvent solutions. They are also available as powders or granules that can be dispersed in water. They are carotenoids. They are unstable to oxygen and light and must be stored in a light-proof container filled with an inert gas. They are insoluble in water and glycerin. They are extremely insoluble in ethanol. They are slightly soluble in vegetable oils and fats (0.7g/100ml) and easily soluble in chloroform (30g/100ml). The melting point is 134-138°C. The natural product is found in egg yolks, etc. | [Uses]
