Key Pharmaceutical Uses
Given your work with chemical formulations and hygiene products, these applications are likely the most relevant:
• Tablet & Capsule Lubricant: Its primary role is to prevent the medicinal powder from sticking to the manufacturing equipment (punches and dies) during compression.
• Emulsifying Agent: In creams and ointments, it helps blend water and oil phases into a smooth, stable texture.
• Hardening Agent: Used in the production of suppositories and solid medicinal sticks to provide structural integrity.
• Controlled Release: It can be used as a matrix-forming agent to slow down the release of active ingredients in the body.
