This International Standard specifies a method for determining the optical rotation of essential oils. When dealing with solid oils, partially solid oils, oils that are highly viscous at room temperature, or highly coloured oils, this determination is carried out on a solution of the oil.
Abstract
Overview
ISO 592:1998 specifies a laboratory method for determining the optical rotation (also called specific rotation) of . Measurements are made using a polarimeter with sodium D-line illumination (589.3 nm ± 0.3 nm). For solid, partially solid, highly viscous or strongly coloured essential oils, the standard requires measurement on a prepared of the oil.
