薄荷油中含薄荷脑及薄荷酮等成分，极微溶于水。用其制备清凉饮料、含嗽剂、薄荷水、痱子水等时，需要加分散剂分散吸附，加增溶剂研磨搅拌增溶或加半极性溶媒稀释等方法溶解，费时费力，操作繁杂影响配制效率。现将其制备成水溶性薄荷油，可直接加入到水溶液中或其它制剂中， Peppermint oil contains components such as menthol and menthone, which are very slightly soluble in water. When using it to prepare refreshing drinks, gargles, peppermint water, and gardenia water, it is necessary to add dispersant to disperse and absorb, add solubilizer, stir and solubilize, or add semi-polar solvent to dilute, etc. Dissolving is time-consuming and laborious, and the operation is complicated to affect the preparation efficiency. . It is now prepared as a water-soluble peppermint oil that can be added directly to aqueous solutions or other formulations.
