Abstract

Official abstract text for this publication.

Suggested are liquid cooling compositions, containing (a) L-Menthol, (b) D-Menthol, and (c) at least one further cooling agent, selected from the group consisting of isomenthol, menthyl acetate (L), menthyl acetate (D), menthyl acetate (iso), acetic acid menthyl lactate (iso) and acetic acid menthyl lactate (neo) with the proviso that in case that component (c) represents Isomenthol, the compositions do not contain any alkanediols.

First claim

Opening claim text (preview).

The invention claimed is: 1. A liquid composition comprising (a) about 50 to about 55% by weight L-menthol, (b) about 25 to about 35% by weight D-menthol, and (c) about 18 to about 23% by weight menthyl acetate (L), with the proviso that all quantities add up to 100% by weight. 2. A sec-end liquid composition, comprising (a) about 50 to about 55% by weight L-menthol, (b) about 25 to about 35% by weight D-menthol, (c1) about 8 to about 12% by weight menthyl acetate (L), (c2) about 8 to about 12% by weight menthyl acetate (D), (c3) about 0.1 to about 1% by weight menthyl lactate (iso), and (c4) about 0.1 to about 1% by weight acetic acid menthyl lactate (neo), with the proviso that all quantities add up to 100% by weight. 3. A liquid composition comprising (a) about 35 to about 45% by weight L-menthol, (b) about 35 to about 45% by weight D-menthol, (c1) about 15 to about 25% by weight menthyl acetate (L), and (c2) about 2 to about 8% by weight isomenthol, with the proviso that all quantities add up to 100% by weight.
