Industrial Applications of WS 12
| Industry | Application | Processing |
|---|---|---|
| Oral Care | Added as a cooling agent to toothpaste, mouthwash, and similar products to deliver sustained cooling sensation | Directly incorporated into the base formulation at 0.01–0.1% concentration with ambient-temperature mixing |
| Tobacco Products | Used in cigarettes and e-liquids to enhance cooling sensation during inhalation | Dissolved in ethanol or propylene glycol, then applied via atomization or coating onto tobacco filler or pods |
| Food & Beverages | Provides cooling sensation in chewing gum, mint candies, and functional beverages | Blended with sugar, flavorings, and other ingredients at 0.001–0.05% dosage, followed by granulation or filling |
| Personal Care | Added to shaving gels, talcum powders, and body washes to enhance cooling sensation upon application | Emulsified or dispersed in the aqueous phase together with surfactants and emulsifiers, followed by homogenization |
| Pharmaceuticals | Used in topical analgesic patches and nasal sprays to alleviate discomfort | Loaded onto drug delivery systems via coating or spray deposition using pharmaceutical-grade carriers (e.g., polyvinyl alcohol) |
Manufacturing Quality Control of WS 12
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with standard spectra to confirm characteristic functional groups and molecular structure of WS-12. |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyze chemical shifts, coupling constants, and other properties of hydrogen atoms in the molecule using NMR technology to verify compound structure. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase C18 column with methanol-water or acetonitrile-water as mobile phase and a UV detector (typically 210–230 nm) for quantitative analysis of the main component content in WS-12. |
| Related Substances / Impurities | High-Performance Liquid Chromatography (HPLC) | Using the same conditions as assay or optimized gradient elution programs, separate and detect impurities such as synthesis by-products and degradation products; quantify using area normalization or correction factor methods. |
| Melting Point | Melting Point Determination | Use a melting point apparatus to measure the temperature range over which the sample transitions from solid to liquid, serving as an auxiliary indicator for purity and identity confirmation. |
| Specific Optical Rotation | Polarimetry | Prepare a solution of known concentration and measure optical rotation at a specified wavelength (usually sodium D line, 589 nm) and temperature, then calculate specific optical rotation to assess chiral purity. |
| Water Content | Karl Fischer Titration | Use volumetric or coulometric Karl Fischer titration to accurately determine water content in the sample, controlling the impact of loss on drying. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection, capillary column, and FID detector to detect organic solvents possibly remaining from manufacturing processes (e.g., methanol, acetone). |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight and calculate the percentage of mass loss, reflecting total volatile substances and moisture content. |
| Sulfated Ash / Residue on Ignition | Residue on Ignition Test | Ignite the sample at high temperature (typically 700–800°C) and measure the amount of inorganic residue to evaluate inorganic salts or metal catalyst residues. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After digesting the sample, measure the levels of heavy metal elements such as lead, arsenic, cadmium, and mercury to ensure compliance with pharmaceutical or food additive safety standards. |
