Product Description:
It is a highly efficient lubricant with lower hydrophobicity than stearic acid. It can avoid problems caused by divalent magnesium ions, significantly reduce the risk of over-lubrication, and minimize film formation in effervescent tablets. Different granules are available upon request. diameter specifications.
The amount of sodium stearyl fumarate used as a lubricant is generally 0.5%-5%, and the specific amount is often determined according to the nature of the main drug and the type and proportion of other excipients. Generally, the ingredients of traditional Chinese medicine extracts contain a large amount of viscous substances and sugars, and the tablet sticking is more serious, so the dosage of hard sodium fumarate can be appropriately increased. Some chemicals that are difficult to dissolve in water have low solubility and slow dissolution, which affects bioavailability. Sodium stearyl fumarate is often used to replace traditional hydrophobic lubricants.
