Menthol crystal
Menthol crystals are cooling, refreshing, and have a pleasantly strong minty aroma. They are often used in cosmetics, salves, balms, medicated creams, throat lozenges, toothpaste, mouthwash, gum, foot sprays, pain relief or cooling body products, shampoos, conditioners, liniments, shaving creams, oral or throat sprays, compresses, medicated oils, and cooling gels. Menthol crystals are excellent for use in these products to help relieve muscular aches and pains, coughing, congestion, the flu, and upper respiratory problems. Since Menthol crystals are so concentrated, only a very small amount is needed within products. When purchasing Menthol crystals remember that a good quality menthol crystal usually contains not less than 99.4% menthol.
