NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing our clients with not only high-quality ingredients but also the knowledge to effectively select and utilize them. Menthol crystal, a widely used natural compound, requires a clear understanding of its specifications to ensure it meets the needs of diverse applications, from food and beverages to cosmetics and fragrances.

When you decide to buy menthol crystal, several key parameters should guide your selection process. Firstly, Assay is critical. For most applications, a 100% assay indicates pure menthol. Secondly, Appearance is a visual indicator of quality. High-quality menthol crystal should present as colorless, clear strips or crystals, free from discoloration or cloudiness.

The Odor of menthol crystal is unmistakably minty and pleasant. Any off-odors could suggest contamination or degradation. Melting Point is another crucial specification; the typical range for pure menthol crystal is 41.5-44.0°C. Deviations from this range can indicate impurities or an incorrect isomer balance, which can affect its sensory properties and performance.

Solubility is important for formulators. The ability of menthol crystal to dissolve readily in common solvents like ethanol (e.g., 1g sample completely soluble into 5 ml 90% ethanol at 25°C) ensures it can be easily incorporated into liquid formulations. Specific Rotation, measured at 25°C, is vital for identifying the specific isomer of menthol and confirming its natural origin or synthesis purity.

Safety and purity are further guaranteed by specifications such as Residue on Evaporation, which should be very low (e.g., ≤0.05%), and limits for Arsenic (As) and Heavy Metals (Pb). These parameters are particularly important for food-grade and cosmetic raw materials to ensure compliance with regulatory standards.

At NINGBO INNO PHARMCHEM CO.,LTD., we rigorously test our menthol crystal to meet these critical specifications. We understand that the quality of your end product depends on the quality of the raw materials you use. Whether you need menthol crystal for flavor enhancement, a cooling sensation in personal care products, or a refreshing note in fragrances, our commitment to purity and consistency ensures you receive an ingredient you can trust.
