角鲨烷

里哪醇与乙酰乙酸乙酯反应制备角鲨烷

角鲨烷(C30H62)又名异三十烷、鲨烷,是由角鲨烯氢化后制得,可用作香脂、营养乳液等基础化妆品油性原料。角鲨烯是从蓝鲨(Centrophorus)或其它深海鲨鱼类肝油中取得,开始作为由鲨鱼肝油生产维生素A的副产物。近年发现,橄榄油不皂化物含丰富的角鲨烯,以它为原料生产角鲨烷(即全氢化角鲨烯)。

英语百科

Squalane 角鲨烷

Squalane is a hydrocarbon and triterpene derived by hydrogenation of squalene. Due to the complete saturation of squalane, it is not subject to auto-oxidation. This fact, coupled with lower costs associated with squalane, make it desirable in cosmetic applications, where it is used as an emollient and moisturizer. The hydrogenation of squalene was first reported in 1916. Squalene is sourced from the livers of sharks. Approximately 3000 sharks are required to produce one ton of squalene. Due to environmental concerns, olive oil as an alternative non-animal source has been developed and commercialized. Another commercial non-animal source is phytosqualane, a compound derived from a farnesene in a sugar-cane sucrose fermentation over genetically modified Sacccharomyces cerevisiae yeast strains. Farnesene is dimerised to isosqualane and then hydrogenated to squalane.
