The oil is prepared using materials and methods designed to ensure that the content of brassicasterol (2.4.23) in the sterol fraction of the oil is not greater than 0.3 per cent.<\/p>\n
Clear, light yellow or yellow oil.<\/p>\n
Practically insoluble in water and in ethanol (96 per cent), miscible with light petroleum (bp: 40-60 \u00b0C) and with methylene chloride.<\/p>\n
