Short Notes on Cleaning Validation
Cleaning validation is a critical process in ensuring that manufacturing equipment and facilities meet stringent cleanliness standards, particularly in industries like pharmaceuticals, biotechnology, and food production. It is essential to demonstrate that cleaning procedures effectively remove residues of active ingredients, excipients, cleaning agents, and microbial contaminants to acceptable levels.
This validation process includes establishing limits for residuals, selecting appropriate analytical methods, and conducting rigorous testing under worst-case scenarios. Proper documentation and adherence to regulatory guidelines are vital to confirm that the cleaning process consistently meets safety and quality requirements, thus preventing cross-contamination and ensuring product integrity.
Worst-case Product
Worst case product is selected based on risk level marking. This risk matrix is predominantly focused on permitted daily exposure value with the highest scale than other risk factor.
When cleaning validation performed?
- Initial qualification of process /equipment.
- Critical change in a cleaning procedure.
- Critical change in formulation.
- Significant change in formulation.
- Change in a cleaning process.
- Change in cleaning agent.
Calculation of maximum allowable carry over Limit (MACO)
Four approaches followed for calculation of MACO
1. Dose based criteria
2. Toxicity based criteria (LD50)
3. PDE/ADE base criteria
4. 10 ppm Criteria
