L Menthol Extract

Shaanxi Rebecca Biotechnology has got ISO9001, HALAL, KOSHER, FSSC22000 and HACCP systems certified.

Our laboratory is equipped with state of the art analytical equipment including HPLC, GC-MS and heavy metal testing devices.

We ensure thorough quality control during the whole manufacturing, from grading of raw materials to multi-step recrystallisation.

Our R&D team optimises chiral catalytic processes with low impurities.

We provide versatile OEM/ODM services for powder granulation, tablet compression and capsule filling according to your formulation needs.

All batches are tested by an independent third party for purity, heavy metals and microbiological limits before to release.

We provide L Menthol Extract by three validated routes:

Natural Extraction: Steam distilled from Asian Peppermint leaves, then freeze crystallised. Climate dependent, yet retains true botanical profile.

Chiral Asymmetric Synthesis: Myrcene is isolated from turpentine and catalytically hydrogenated with Rh-BINAP to give constant L-configuration with adjustable isomer content – perfect for pharmaceutical grade.

Resolution of racemates Preparation of DL-menthol and its resolution by esterification. Mainly used in cost-sensitive daily chemical applications.

Each batch may be traced back to approved raw material lots with documented origin, processing date and quality certificates in compliance with EU EC396 and 2023/915.

Solubility Characteristics:

· Cold water: ~0.4 g/L

· Hot water, ethanol, propylene glycol: Readily soluble

· Vegetable oils and fragrance solvents: Fully miscible

· Pure aqueous systems: Requires emulsifiers to prevent precipitation

Stability Considerations:

· Thermal: Sublimation begins above 35°C; prolonged exposure beyond 80°C causes volatilization. Avoid heating above 120°C to prevent isomerization.

· pH Range: Stable between pH 4.0–8.5. Extreme acidity/alkalinity induces racemic degradation.

· Light: UV exposure triggers oxidation and yellowing. Store in opaque containers.

· Moisture: Non-hygroscopic but highly sublimable. Seal tightly in foil bags within moisture-proof drums. Shelf life: 24 months unopened.

We follow eight crucial stages in our production process to assure pharmaceutical-grade quality:

Pretreatment: Myrcene is vacuum distilled to remove sulphides and polymeric contaminants. Materials are degassed and kept under nitrogen atmosphere

Chiral Catalytic Hydrogenation: Rh-BINAP catalyst guides the creation of L-configuration in closed high-pressure reactors. Real-time GC monitoring ensures conversion efficiency and suppresses D-isomer production.

Purification: Catalyst residues and salts are removed by acid-alkali neutralisation and multistage washing. Organic phases are well dehydrated.

Vacuum Distillation: Gradient fractional distillation removes light impurities, enriches high purity middle fraction, and removes heavy oxidised components under nitrogen blanket.

Recrystallisation: Controlled cooling crystallisation in ethanol-water solvent systems. Pharmaceutical grades are decolorised by three cycles of activated carbon to reduce the allergenic menthone and menthofuran content.

Crystal Processing: Cold Solvent Rinses of Filter Cakes Vacuum drying at temperatures below 40°C avoids loss through sublimation.

Optional: Cyclodextrin Inclusion: β-Cyclodextrin complexation for slow release, anti-sublimation powders via high pressure homogenisation and spray drying.

Finish: Precision ground to 80-200 mesh, batch homogenised for uniformity and packaged in sealed foil with complete analytical testing prior to warehousing.

Oral Care: Immediate freshness and long lasting coolness are beneficial for toothpastes, mouthwashes, and breath sprays. Increases consumer satisfaction with dental floss and periodontal gels.

Food Industry Its refreshing minty character is utilised in sugar-free gums, hard candies, throat lozenges, functional beverages and chocolate flavouring.

Topical Pharmaceuticals: Muscle rubs, anti-pruritic creams, nasal decongestants and transdermal patches use weak analgesic and penetration-enhancing characteristics.

Cosmetics: Shaving products, after-sun gels, oil-control shampoos, mosquito repellents and acne serums – it’s all about cooling comfort and sensory stimulation.

Tobacco/Vaping: Smooth cooling, no harshness, with cigarette filters and e-liquid bases.

Each production batch is tested under stringent methods to international standards. Certified laboratories check L-menthol concentration, chiral purity, D-isomer levels, heavy metals (Pb 3ppm), solvent residues and microbiological limits. Third-party audits confirm compliance to cGMP, NOP organic, and FSSC22000 food safety systems. Full documentation allows full traceability across the whole supply chain from raw material harvest to final packaging.

Standard Packaging: Aluminium foil inner bags double-sealed in 25kg moisture-proof fibre drums to minimise sublimation loss.

Custom Options: Smaller amounts, anti-sublimation inclusion powders or certain mesh sizes available on request.

Delivery Options: FedEx or DHL for samples, air or sea freight for bulk orders. Stability data accelerated long distance transport planning supplied.

Q: How do you control sublimation during international shipping?

A: Double-sealed foil bags and fibre drums decrease vapour loss. We give expedited weight loss test results to predict content stability during your shipping cycle.

Q: How do you get batch to batch consistency?

A: Incoming QC for continuous production is smooth since raw materials are pre-screened, standardised purification techniques are used, and completed batches are homogenised to narrow melting point, odour and assay variations.

Q: Do you lock rates for annual contracts even with seasonal mint price swings?

A: Yes. During harvest peaks we stockpile eligible materials and for framework clients we provide fixed price quarterly agreements hedging volatility and providing uninterrupted supply.
