Menthol Crystals
Botanical Name:Mentha Arvensis
Menthol crystals are a natural product derived from Mentha arvensis oil. The process involves fractional distillation of the oil to obtain L-Menthol Terpeneless, which is then crystallized. These crystals are characterized by their distinctive hexagonal or needle-like bold structure. They are super dry, transparent, and colorless. Menthol crystals possess a strong mint odor and exhibit natural cooling properties.Menthol Bold Crystal BP Specifications
