Quality Control of Nanoemulsion: by PDCA Cycle and 7QC Tools.

Despite several quality management tools, none or very few systematic operations are taken into account to assure the quality of the pharmaceutical products. Plan Do Check Act (PDCA) analysis is performed based on the problems encountered during the product development. In each step, some of the quality control tools are used for better maintenance of corrective and preventive actions. However, systematic use of these tools is still not made. Here we portray an example of nanoemulsion that will help justify the correct or systematic use of all the seven quality control tools in each section of PDCA cycle for better maintenance of Corrective and Preventive Actions (CAPA). The major limitations associated with the nanoemulsion i.e. non-uniform size distribution, lower encapsulation efficiency, lower magnitude of zeta potential, non-scalable and expensive synthesis procedures have taken into consideration for this portray. This review summarizes the productive use of 7 QC tools in PDCA cycle to ensure the optimum quality of nanoemulsion in an industry.
