Applications;
1. Tablet and capsule manufacturing: Zinc Stearate is commonly used as a lubricant and flow agent in tablet and capsule production. Similar to stearic acid, it helps in the smooth release of the tablet or capsule from the mold and prevents sticking during manufacturing processes.
2. Topical preparations: Zinc Stearate can be found in various topical formulations such as creams, ointments, and lotions. It acts as an emulsifier and stabilizer, improving the texture, consistency, and spreadability of the formulation.
3. Powdered formulations: Zinc Stearate is used in powdered formulations, including medicinal powders and dusting powders. It helps to improve flow properties, prevent caking, and provide a smooth texture.
4. Controlled-release drug delivery systems: Zinc Stearate can be incorporated into controlled-release drug delivery systems, similar to stearic acid. It aids in controlling the release rate of active pharmaceutical ingredients (APIs) over an extended period.
5. Pellet coating: Zinc Stearate is sometimes used as a coating material for pellets or granules in pharmaceutical manufacturing. It helps to improve the flow properties, prevent agglomeration, and provide a smooth and uniform coating on the pellets.
