Compliance with major pharmacopeias such as USP/NF and Ph. Eur. ensures safety and reliability. Its stability, low microbial count, and high purity make it suitable for sensitive pharmaceutical applications.
Safe Handling and Convenient PackagingThe product is shipped in secure HDPE or fiber drums with double polythene liners, minimizing contamination risk and moisture exposure. Its recommended storage is below 25C in cool, dry conditions. With a shelf life of 24 months, Sodium Stearyl Fumarate retains its efficacy and functionality when stored properly, ensuring reliable supply to manufacturers and suppliers.
FAQs of Sodium Stearyl Fumarate:
Q: What is Sodium Stearyl Fumarate and how is it used in pharmaceutical formulations?
A: Sodium Stearyl Fumarate is a highly compressible, non-toxic powder primarily used as a tablet lubricant in pharmaceutical formulations, especially for the direct compression method. It helps reduce friction and prevents tablets from sticking to manufacturing equipment.
Q: How is Sodium Stearyl Fumarate manufactured?
A: It is produced by esterification of stearyl alcohol with fumaric acid, followed by a saponification process. This method ensures high chemical stability and optimal purity.
Q: When should Sodium Stearyl Fumarate be used in tablet production?
A: It is particularly suitable for direct compression tablet manufacturing processes where superior lubrication and minimal metal contamination are essential.
Q: Where is Sodium Stearyl Fumarate typically stored and how should it be handled?
A: It should be stored in a tightly closed container in a cool, dry place, protected from moisture and at temperatures below 25C to maintain product stability and prevent degradation.
Q: What are the benefits of using Sodium Stearyl Fumarate in pharmaceutical tablets?
A: Using this excipient enhances tablet compressibility, ensures chemical stability throughout shelf life, and prevents sticking during production, leading to higher manufacturing efficiency and product consistency.
Q: Is Sodium Stearyl Fumarate safe and allergen-free for pharmaceutical use?
A: Yes, the product is non-toxic, odorless, tasteless, and free from allergens. It complies with USP/NF and Ph. Eur. standards and maintains low microbial and heavy metal limits, assuring safety in pharmaceuticals.
Q: What is the typical packaging and shelf life of Sodium Stearyl Fumarate?
A: It is supplied in HDPE or fiber drums with double polythene liners for optimal protection, and, when properly stored, has a shelf life of up to 24 months.
