Pharma Ointment Residue via CIP Detergent
Q. We are a generic pharmaceutical manufacturer of Creams and Ointments. We are having difficulty cleaning equipment (specifically CIP) after making these types of products. We have been successful in cleaning 95% of our products using the alkaline detergent. We have couple of products that leave a white film after the cleaning cycles. These products do not contain metal oxides. We are planning to try the Citranox acid cleaner. Any suggestions?
