Abstract

The Standard specifies certain characteristics of the oil. Descriptions and permissible values are given of aspect, colour, odour, relative density at 20/20 °C, refractive index at 20 °C, optical rotation at 20 °C, miscibility with 70 % (V/V) ethanol at 20 °C, acid value, ester value, ester value after acetylation, carbonyl value, and apparent citronellol (rhodinol) content. Most of the values differ dependent on the country of origin (Bourbon, Algeria, Morocco, India, Kenya, Egypt, U.S.S.R.).
