The crystals are soluble in alcohol, essential oils and vegetable/nut oils, but almost insoluble in water and glycerin. The use of Polysorbate 20 is recommended for water applications. Melting point 41 C to 44 C (105.8 F to 111.2 F), boils at 212 C (413.6 F). Menthol crystals start to evaporate at 21 C (70 F). The crystals contains not less than 99.4% menthol.
Menthol is the chief constituent of peppermint oil; it is responsible for its odor and taste and the "cooling sensation" when applied to the skin and mucosal surfaces. Mentha piperita contains up to 50% menthol and Mentha arvensis contains 70-80% menthol. Menthol crystals should be kept in a cool place in a well-capped container. Menthol is the solid constituent of oil of peppermint, to which its characteristic odor is due, and was formerly known as peppermint camphor. Menthol is obtained by subjecting the distilled oil of peppermint to a temperature of -22 C, (-7.6 F.) by the aid of a freezing mixture. The menthol crystallizes out in satiny crystals and the mother liquor is removed while the low temperature is maintained.
Menthol and its derivatives can also be added to various peppermint-type compositions to enhance the cooling and freshening effects. Menthol is used in pharmaceutical, confectionery and flavoring industries. In ointments, liniments, and solutions menthol crystals are employed in strengths ranging from 5 to 20 per cent. The crystals are commonly applied to cosmetics, salves and balms which are created to assist in coughs, congestion, upper respiratory problems, and the flu. Menthol crystals are great inhalants by themselves and are easily combined into recipes. Add several drops to a bowl of hot, steamy water and carefully inhale the soothing vapors through the mouth and nose for stuffiness and bronchitis. Once you have converted the crystals to liquid, use a few drops on the tiles of the walls surrounding your shower (not on the floor!) and the menthol will be released by the steam created by the hot water. Externally, it is employed as a local analgesic. Diluted and rubbed on the skin, it produces a sensation of cold, followed by numbness and partial anesthesia; it first stimulates the nerves, conveying the sensation of cold, and later penetrates the skin and paralyzes the nerve endings. Known ingredients of Vicks VapoRub: Camphor, menthol, eucalyptus, cedarleaf, nutmeg, thymol and turpentine.
Menthol crystals are soluble in alcohol, EOs/FOs and oil, but almost insoluble in water and glycerin. Use rate: 1 part menthol to 3-4 parts Polysorbate 20.
Because menthol and alcohol are very strong it is important to keep the temp no higher than 41deg. C (106 deg. F). Menthol crystals start to evaporate at 21 deg. C (70 deg. F) so you will get a whiff just before they hit that melt point. Best to remove and let them finish melting off heat to avoid the vapors.
If used in soapmaking, it might be best to put them in the oil phase so that they don't interfere with the action of the lye in the water phase. In whatever recipe you will use menthol crystals, make sure they are well stirred and dissolved to avoid skin reactions.
