Flüssige L-N-Menthol-Zusammensetzung und Verfahren zu deren Herstellung

摘要

A liquid l -n-menthol composition contains 30 to 80% by weight of (-)-n-isopulegol and is prepared by mixing 20 to 70 parts of liquid menthol at a temperature of not lower than 42 DEG C, as obtained in the production of l -n-menthol, with 30 to 80 parts by weight of (-)-n-isopulegol. 20 - 80% by weight of the (-)-n-isopulegol may be replaced with 3- l -n-menthoxypropane-1,2-diol. The liquid l -n-menthol composition is a cheaper replacement for conventionally-available menthol and yet has an improved feeling of coolness (the bitterness in particular being reduced); moreover, the composition has excellent workability and hygienic properties in use. By replacing part of the (-)-n-isopulegol component with 3- l -n-menthoxypropane-1,2-diol, both the odor of menthol and the irritation of the skin by menthol can be softened, and the feeling of mildness enhanced.
