Cholesteryl nonanoate, also called cholesteryl pelargonate, 3β-cholest-5-en-3-ol nonaoate or cholest-5-ene-3-β-yl nonanoate, is an ester of cholesterol and nonanoic acid. It is a liquid crystal material forming cholesteric liquid crystals with helical structure. It forms beautiful spherulite crystals.[1]


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].

It can be also used as a component of the liquid crystals used for liquid crystal displays.
