In pharmaceuticals, what does the term "levigating agent" refer to?

A levigating agent is a substance used in the pharmaceutical compounding process to help reduce the particle size of solid ingredients and create a smoother texture in formulations, particularly in the preparation of ointments and creams. By preventing lumps during the mixing process, it ensures a more uniformly blended and effective product.

This agent helps facilitate the dispersion of powders in liquid or semi-solid carriers, thus enhancing the overall consistency and stability of the formulation. Its primary function is to promote a homogenous mixture without the formation of clumps, making it essential for achieving the desired viscosity and palatability in compounded medications.
