Defoaming test as per USP?

The defoaming test as per the United States Pharmacopeia (USP) evaluates the efficacy of a defoaming agent in reducing or inhibiting foam formation in pharmaceutical formulations. This test typically involves adding the defoaming agent to a specified volume of a foaming solution and measuring the time taken for foam to dissipate or the volume of foam produced. The results help ensure product stability and performance, particularly for liquid formulations like emulsions or suspensions. Compliance with USP guidelines ensures that the defoaming agent's effectiveness meets required pharmaceutical standards.
