gum acacia, also known as acacia gum or gum arabic, is a natural substance derived from the sap of the acacia tree. It has a long history of use in the pharmaceutical industry as a binder, dispersant, and tablet-coating agent. Gum acacia has a high molecular weight, making it an ideal ingredient for maintaining the stability and uniformity of solid dosage forms like tablets and capsules. It has good hydrophilic properties, which allow it to absorb water and form gel-like structures. This helps to improve the flowability of powders, making them easier to handle and manufacture. Additionally, gum acacia has good compatibility with other pharmaceutical excipients, making it a suitable ingredient in multi-component formulations. Overall, gum acacia is considered a safe and effective excipient in the pharmaceutical industry, and is widely used in the manufacture of various types of medicines.
