Menthol
Menthol is an organic compound that is typically derived from herb plants such as peppermint and eucalyptus.
Menthol occurs naturally in peppermint and is usually extracted from peppermint oil, other mint oils, or created synthetically. The most popular species of mint used to produce menthol is known as mentha arvensis. It exists in several stereoisomeric forms so they have different CAS No.
It is a waxy, clear or white crystalline substance, which is solid at room temperature and melts slightly above.
It is widely used in cosmetic, personal care, and pharmaceutical formulations for its cooling, soothing, and fragrance properties.It can stimulate blood circulation, potentially causing a temporary plumping effect, and has antibacterial qualities. While beneficial for stimulating and soothing skin, menthol should be used sparingly and avoided around the eye area due to its potential to cause irritation.
The cooling effect of menthol is due to the activation of the TRPM8 receptor in the skin.
L-menthol produces the strongest activation of this receptor, so is a more intense and longer-lasting cooling sensation compared to D-menthol or racemic menthol.
