化学的特性Hydrogenated castor oil occurs as a fine, almost white or pale yellow powder or flakes. The PhEur 6.0 describes hydrogenated castor oil as the oil obtained by hydrogenation of virgin castor oil. It consists mainly of the triglyceride of 12-hydroxystearic acid.Hydrogenated castor oil — also called HCO or castor wax — is a hard, white, opaque vegetable wax. Its resistance to moisture makes it useful in many coatings, greases, cosmetics, polishes and similar applications.The wax is created by hydrogenating pure liquid castor oil, which is obtained from castor beans. The oil is heated under extreme pressure using a nickel catalyst during the hydrogenation process. Afterward, the hydrogen creates saturated molecules of castor wax, which gives the oil a higher melting point that allows it to remain solid at room temperature. After hydrogenation, the oil becomes hard and brittle to the touch.

説明Hydrogenated castor oil is a waxy compound obtained by the hydrogenation of refined castor oil. It is a hard product with a high melting point. It is almost odourless and tasteless. HCO is supplied in flakes and powder. Hydrogenated castor oil is cream to white coloured. appearance white to creamish flakes or powder melting point °C 83 - 87 colour Gardner max. 3 colour (on 1” Lovibond) max 20 yellow / max.2 red acid value mg KOH/g max. 5 iodine value g/100g max. 5 hydroxyl value 155 - 165 saponification value mg KOH/g 180 - 190

使用greases: Lithium- and Calcium hydroxystearates dispersed in base oil to make multipurpose greases having higher dropping points, hardness, better rust-proofing, lubricity and durability than stearates. other lubricants: metal drawing lubes, PVC lubricants for PVC pipes, profiles, sheets, pharma tabletting, metal powders, ceramics. cosmetics: HCO of different melting points used in lipsticks, deodorant and antiperspirant sticks, cosmetic creams. slip additive in inks, paints, plastics (PE). dispersing agent in plastic colour master batches, carbon papers, inks. flow control and dispersing additive in powder coatings, hot-melt adhesives and sealants. shoe polishing, furniture polishing creams.
