Industrial Applications of Sodium carboxyl methylstarch
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Disintegrant for oral solid dosage forms | Added as a high-efficiency disintegrant during tablet manufacturing to facilitate rapid disintegration and drug release in the gastrointestinal tract |
| Food | Thickener and stabilizer | Applied in dairy products, condiments, and other food items to improve texture and stability, and enhance suspension performance |
| Cosmetics | Emulsion stabilizer and thickener | Incorporated into emulsions, creams, and similar products to increase viscosity and physical stability |
| Medical Devices | Component of medical dressings | Used in wound dressings to maintain a moist wound environment, leveraging its water-absorbing capacity and biocompatibility |
Manufacturing Quality Control of Sodium carboxyl methylstarch
| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Differentiation | Infrared Spectroscopy (IR) | Compare the sample with standard spectra, observing characteristic absorption peaks (e.g., C=O stretching vibration of carboxymethyl group around 1600 cm⁻¹, symmetric stretching of -COO⁻ around 1420 cm⁻¹), to confirm the structure. |
| Dry Loss | Thermogravimetric Analysis or Oven Drying Method | Dry the sample at 105°C until constant weight, measure the loss in weight, and control moisture content, typically requiring ≤10.0%. |
| Residue on Ignition (Sulfuric Ash) | Gravimetric Method | The sample is ignited at high temperature and treated with sulfuric acid; the residual inorganic matter is measured to reflect the level of inorganic impurities. |
| Substitution Degree (DS) | Acid-Base Titration or Elemental Analysis | Determine the carboxyl group content via acid-base titration and calculate the average number of carboxymethyl groups per glucose unit (typically 0.1–0.3). |
| pH Value | pH Meter Measurement | Measure the pH of a 1% aqueous solution after stirring, using a pH meter. The value is generally required to be between 6.0 and 8.5. |
| Viscosity | Rotational Viscometer Method | Prepare a solution of a certain concentration (e.g., 1%) and measure its dynamic viscosity at a specified temperature (e.g., 25°C), reflecting molecular weight and flow properties. |
| Heavy Metals | Sulfide Colorimetric Method or Atomic Absorption Spectrometry | Detect lead, arsenic, and other heavy metals according to pharmacopoeia methods. Typically, total heavy metals should be ≤ 20 ppm. |
| Microbial Limits | Microbial Counting Method and Control Bacteria Check | Perform aerobic bacterial count, mold and yeast count, and check for control bacteria (such as Escherichia coli) according to the Chinese Pharmacopoeia or USP. |
| Particle Size Distribution | Laser Particle Size Analysis or Sieving Method | Determine the particle size distribution of the powder to ensure it meets the requirements for formulation processes (e.g., flowability for oral solid dosage forms). |
| Sodium Chloride and Sodium Glycolate Residual | Ion Chromatography or Titration | Detect residual sodium chloride or crosslinking agent sodium glycolate from the synthesis process to ensure compliance with safety limits. |
