Menthol Crystals Extra Pure
Menthol Crystals Extra Pure are colorless to white, needle-like crystals derived from peppermint or other mint oils and refined to the highest purity. Known for their strong, refreshing minty aroma, they are widely used in pharmaceutical, cosmetic, and personal care formulations. These crystals provide a cooling sensation on the skin and mucous membranes, making them a common ingredient in balms, liniments, throat lozenges, and inhalants. In laboratories, menthol crystals are also used in sensory studies and product development. Their purity ensures consistent performance and minimal interference in sensitive formulations.
Menthol Crystals Extra Pure
Primary Laboratory Uses:
- Standard in Sensory and Olfactory Studies:
- Used in research involving olfactory receptors, cooling sensation studies, and neurological responses to aromatic compounds.
- Pharmaceutical Formulation Research:
- Commonly employed in experimental drug formulation (ointments, lozenges, creams) for studying local anesthetic and decongestant properties.
Secondary Laboratory Uses:
