Particle Size and Shape of Ointments and Creams

Ointments and creams used in the pharmaceutical and cosmetics industry may contain solid particles and/or emulsion droplets. Analyzing these particles in the final product is currently performed by manual microscopy or automated image analysis. Automated image analysis has the benefits of quickly measuring thousands of particles and reporting both particle size and shape distribution results. This study utilizes the PSA300 automated image analysis system to quantify the size and shape of various ointments and creams.
