It is a liquid crystal material forming cholesteric liquid crystals with helical structure. It forms beautiful spherulite crystals.[1]

Additional recommended knowledge

Uses

It is used in some hair colors[2], make-ups, and some other cosmetic preparations[3]. It is also used in some pleochroic dyes and together with eg. cholesteryl oleyl carbonate and cholesteryl benzoate in some thermochromic applications[4].
