Menthol Crystals

Menthol crystals are made by the fractional distillation of menthol oil. The distilled oil yields pure menthol as a fraction, that is gradually cooled and crystallized. It is Manufactured by extraction of menthol from menthol oil. The oil is chilled to a temperature of -40°C to separate the menthol, which is later crystallized by slow cooling. These crystals are available in the following two grades and confirm to IP/BP/USP/JP/ FCC-III standards.

• Menthol large crystals
• Menthol small crystals
