Industrial Applications of 2-ISOBUTYL-4-HYDROXY-4-METHYLTETRAHYDROPYRAN
| Industry | Application | Process |
|---|---|---|
| Personal Care & Fragrances | Used as a fixative and modifier in floral fragrance compositions (e.g., lily of the valley, lily), imparting a fresh, elegant green-floral character | Incorporated into fragrance formulations for premium perfumes, body washes, soaps, and shampoos, typically at 0.1–5% w/w |
| Food Flavorings | Used as a food flavoring agent to simulate or enhance fruity and floral notes (e.g., pear, apple, lily of the valley) | Approved as a synthetic flavoring substance under GB 2760–2024 “National Food Safety Standard – Usage Standard for Food Additives”; applied in soft drinks, confectionery, ice cream, etc., with maximum usage levels dependent on food category (typically ≤10 mg/kg) |
| Tobacco Industry | Used as a component in cigarette flavorings to enhance aroma richness and smoothness of mainstream smoke | Incorporated into tobacco sheet flavorings or filter tip flavorings, loaded onto tobacco materials via spraying or impregnation |
Manufacturing Quality Control of 2-ISOBUTYL-4-HYDROXY-4-METHYLTETRAHYDROPYRAN
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity Determination | Gas Chromatography (GC) | Uses a capillary column for separation and an FID detector for quantification. Purity of the main component is calculated by peak area normalization or external standard method. Suitable for volatile organic compounds. |
| Assay/Content Determination | High-Performance Liquid Chromatography (HPLC) | Employs a C18 reversed-phase column with UV detection (e.g., 220–254 nm). Target compound content is quantified using the external standard method, suitable for thermally unstable or highly polar compounds. |
| Moisture Content | Karl Fischer Titration | Relies on the quantitative reaction of iodine with sulfur dioxide in a pyridine/methanol system with water. The endpoint is determined potentiometrically for accurate measurement of trace moisture in samples. |
| Heavy Metal Residues | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After acid digestion of the sample, ICP-MS simultaneously detects residual elements such as lead, arsenic, cadmium, and mercury. Offers high sensitivity and complies with safety standards for cosmetics and fragrances. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | The sample is sealed and heated to allow volatile solvents to enter the headspace, followed by analysis via GC-FID or GC-MS to quantify residual organic solvents such as methanol, ethanol, and acetone. |
| Acid Value/Free Acid | Acid-Base Titration | Phenolphthalein is used as an indicator, and free acids in the sample are titrated with standardized sodium hydroxide solution. Acid value (mg KOH/g) is calculated to assess product stability. |
| Refractive Index | Abbe Refractometer Method | Measures refractive index at 20°C, commonly used as a preliminary indicator of purity and consistency in the fragrance industry. |
| Relative Density | Density Bottle Method or Digital Densitometer | Determines sample density at 20°C and compares it with standard values to help identify adulteration or degradation. |
| Microbial Limits | Plate Count Method / Membrane Filtration Method | Tests total aerobic bacteria, molds, and yeasts according to Chinese Pharmacopoeia or ISO standards to ensure hygienic safety, especially for personal care or skin-contact products. |
| Sensory Evaluation (Aroma) | Professional Perfumer Olfaction + GC-O | Trained perfumers describe and score aroma characteristics; combined with Gas Chromatography-Olfactometry (GC-O) to identify key odor-active components. |
