A mixture (M1) comprises (wt.%): racemic d,l-menthol and optionally l-menthol (72-85); d,l-isomenthol (7.5-20); a first alkylene diol and optionally at least one further alkylene diol (7-11); and further ingredients (0-2), and where the mixture is liquid at a pressure of 101325 Pa and a temperature of >= 20[deg] C. Independent claims are included for the following: (1) a product comprising the mixture (M1) and further ingredients, where the further ingredients do not contain menthol and/or isomenthol, or alkylene diol; (2) preparing (P1) the product involving preparing the mixture (M1); and mixing or contacting the mixture with further ingredients, where the further ingredients do not contain menthol and/or isomenthol; (3) preparing the mixture (M1) involving mixing the racemic d,l-menthol and optionally the additional l-menthol with the d,l-isomenthol in an amount of 7.5-20 parts by weight (pbw), the first alkylene diol and optionally further alkylene diols in a total amount of 7-11 pbw, and the further ingredients in a total amount of 0-2 pbw; and (4) lowering the melting point of d,l-menthol that is optionally in the presence of additional l-menthol to a temperature of = 20[deg] C at a pressure of 101325 Pa involving mixing d,l-menthol that is optionally in the presence of additional l-menthol with a first alkylene diol and optionally further alkylene diols. |
