Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH3)2SO. This colorless liquid is an important polaraprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water.
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.
