A method of isolating and purifying (−)-Ambrox comprising the step of selectively crystallizing (−)-Ambrox from a reaction mixture comprising one or more of the compounds (II), (III) and (IV)
A method of improving or enhancing the odour of (−)-Ambrox comprising the step of separating (−)-Ambrox from a mixture comprising one or more of the compounds (II), (III) or (IV)
- by selective crystallization of (−)-Ambrox from the mixture, such that after the step of separating, (−)-Ambrox contains none, or only olfactory acceptable amounts, of the compounds (II), (III) or (IV).
A perfume ingredient consisting of (−)-Ambrox and olfactory acceptable amounts of one or more of the compounds (II), (III) or (IV)
