• Basic Information
  • Source: Usually made from the caryopsis of corn (a gramineous plant) or the tuberous roots of cassava (a euphorbiaceous plant), and can also be extracted from potato tubers.
  • Chemical Formula: (C6​H10​O5​)n​
  • CAS Number: 9005 - 25 - 8
  • Appearance: White powder, odorless and tasteless.
  • Solubility: Insoluble in cold water or ethanol. When added with water and boiled, it can form a white - like translucent gel after cooling.
• Quality Standards
  • Acidity: Take 20.0g of this product, add 100ml of water, shake for 5 minutes to mix evenly, and immediately determine according to the law. The pH value of corn starch should be 4.5 - 7.0, and that of potato starch should be 5.0 - 8.0.
  • Loss on Drying: Dry at 105℃ for 5 hours. The weight loss of corn starch shall not exceed 14.0%, and that of cassava starch shall not exceed 15.0%.
  • Ash Content: Take about 1.0g of this product, incinerate it until it is completely ashed and weigh it constantly. The ash left by corn starch shall not exceed 0.2%, and that of cassava starch shall not exceed 0.3%.
  • Microbiological Limit: The number of bacteria in each 1g of the test product shall not exceed 1000, the number of molds shall not exceed 100, and Escherichia coli shall not be detected.
• Performance Characteristics
  • Good Disintegration Property: It has good water - absorbing and swelling properties, which can promote the rapid disintegration of tablets or capsules in the gastrointestinal tract, help the drug release more quickly, and improve bioavailability.
  • High Stability: It has relatively stable chemical properties, good compatibility with most drug components, and is not easy to have chemical reactions, which can ensure the stability of drug quality.
  • High Safety: As a natural polymer material, it is non - toxic and non - irritating, meeting the safety requirements of pharmaceutical excipients.
• Production Method: Generally, medicinal starch is extracted and refined from plant raw materials through processes such as cleaning, crushing, filtering, precipitating, and drying.
• Application Fields
  • Disintegrant: Commonly used in tablets, granules, capsules, etc., to help the preparation disintegrate quickly in the body. For example, it can accelerate the drug release in aspirin tablets.
  • Filler: It can increase the volume of the drug, make the preparation reach the required specification, and ensure the accuracy of the drug dose. It is commonly used in a variety of oral solid - state preparations.
  • Thickening Agent: It can increase the viscosity of liquid preparations in liquid preparations. For example, in some oral liquids, it can improve the use feeling of the drug.
  • Stabilizer: It is used to stabilize the physical properties of liquid preparations, prevent the decomposition or precipitation of active ingredients, such as playing a role in some suspensions.
• Packaging and Storage
  • Packaging: Commonly 25KG/bag.
  • Storage: It should be sealed and stored in a dry place to prevent moisture and deterioration.
