NINGBO INNO PHARMCHEM CO.,LTD. provides essential chemical ingredients, and we understand that our clients value detailed information about the products they procure. Menthol crystal, a naturally occurring organic compound, is a prime example of an ingredient where understanding its scientific properties is key to successful application. From its molecular structure to its physical characteristics, the science behind menthol crystal dictates its performance across various industries.

Chemically, menthol is known as 2-isopropyl-5-methyl-cyclohexanol, with the molecular formula C10H20O. Its CAS number, 2216-51-5, serves as a unique identifier in chemical databases. The purity of menthol crystal is often assessed through various parameters. For instance, the melting point (typically 41.5-44.0°C) is a critical indicator of purity; deviations can suggest the presence of impurities or incorrect isomer ratios. Similarly, the specific rotation, measured at 25°C, provides insight into the enantiomeric purity, which is crucial for its sensory properties.

The sensory attributes of menthol crystal are directly linked to its chemical structure. The characteristic cooling sensation is due to its interaction with TRPM8 receptors in the skin and mucous membranes. This physiological effect makes it highly sought after for applications in toothpaste, mouthwash, and topical cooling agents. The pleasant menthol odor is another defining characteristic, making it valuable in fragrance compositions and air fresheners.

When considering procurement, understanding the specifications is vital. Residue on evaporation, arsenic content, and heavy metal levels are all crucial safety and quality metrics. For instance, a residue on evaporation of ≤0.05% is a standard benchmark for high-quality menthol crystal. Ensuring these levels are met is essential, especially for food-grade and cosmetic raw materials. NINGBO INNO PHARMCHEM CO.,LTD. rigorously tests its menthol crystal to meet or exceed these stringent industry standards.

The solubility of menthol crystal in solvents like ethanol is another important property, influencing how easily it can be incorporated into different product formulations. A 1g sample being completely soluble in 5ml of 90% ethanol at 25°C indicates good solubility. This is particularly relevant when developing liquid formulations, such as mouthwash or fragrance oils.
