What materials are commonly used as carriers in Granule formulations?

Granule formulations rely on materials that can effectively act as carriers to support the release and distribution of active ingredients. Clay, corn cobs, and sawdust are commonly used because they are natural and biodegradable substances that provide a stable and consistent medium for holding the active compounds.

Clay serves as an excellent adsorbent and helps in binding the formulation together, while corn cobs and sawdust provide bulk and texture, which is essential for the granule's handling and application characteristics. The use of these materials also contributes to a slow release of the active ingredients, helping in effective delivery over time.

On the other hand, water and solvents are primarily used in liquid formulations rather than granulates, while microcapsules and emulsifiers are more relevant in encapsulation processes or emulsified products. Heavy metals and phosphates are not suitable carriers due to regulatory concerns and potential environmental impacts. Therefore, the combination of clay, corn cobs, and sawdust aligns well with the requirements for a successful granule formulation.
