1. Basic Information
C22H39NaO4
- Molecular Weight: 390.54
- CAS Number: 4070 - 80 - 8
- Appearance: It presents as a white or off - white powder, which may contain coalesced flat spherical particles.
- Melting Point: 224 - 245℃ (with decomposition)
- Solubility: Slightly soluble in methanol, and practically insoluble in water, ethanol or acetone.
2. Quality Standards
Calculated on an anhydrous basis, the content of
C22H39NaO4
should be within the range of 99.0% - 101.5%.
3. Performance Characteristics
- Good Hydrophilicity: As a hydrophilic lubricant, it shows little sensitivity to dosage and mixing time. Different dosages and mixing times have almost no impact on the compressibility, disintegration and dissolution of tablets.
- High Stability: It is stable under normal temperature and pressure conditions. It has relatively inert chemical properties and exhibits good compatibility with a variety of active pharmaceutical ingredients (APIs).
4. Production Method
Typically, it is prepared by the ring - opening esterification of maleic anhydride and stearyl alcohol, followed by an isomerization reaction to form the salt.
5. Application Fields
- Mainly used as a lubricant for tablets and capsules, with a common dosage of 0.5% - 2.0%. It can improve the disintegration and dissolution performance of tablets, enhance bioavailability, and serves as an excellent substitute for magnesium stearate. It is suitable for a variety of pharmaceutical formulations such as ibuprofen and salicylic acid.
- It can form a protective film in effervescent tablets. It can also be used as a taste - masking agent in dextromethorphan hydrobromide orally disintegrating tablets.
- Food Field: The FDA allows it to be directly added to baked goods, flour - thickened foods, etc. as a regulator and stabilizer, with a usage amount accounting for 0.2% - 1.0% of the food weight. It can be used as a dough quality improver, a stabilizer for baked products, and a thickening agent for starch or wheat flour.
- In laundry detergents, it can be used as an adjuvant for surfactants to increase the lipid solubility of detergents.
- In metal antifreeze, it can form a protective film on the metal surface, enhancing the protective performance.
6. Packaging and Storage
- Packaging: Common packaging includes 1KG/bag, 10KG/box, etc.
- Storage: It should be stored in a sealed and dry place, away from light.
