There are three (3) most relevant factors to consider in cleaning validation design.
1. Placebo Product
A placebo batch in the equipment under essentially the same operating parameters used for processing products can be used to evaluate and validate cleaning processes.
A sample of the placebo batch must be tested for residual contamination.
2. Product Contact Surface
Select the correct surface area in which the product or patient shall be in contact to perform the recovery tests and cleaning validation execution.
3. Detergent Agent
Determine and consider the difficulty that may arise when attempting to test for residues when a detergent or soap is used for cleaning.
A common problem associated with detergent use is its composition.
Many detergent suppliers will not provide a specific composition, which makes it difficult for the user to evaluate residues.
As with product residues, it is important and it is expected that the manufacturer evaluates the efficiency of the cleaning process for the removal of any residues, including detergent residues.
However, unlike product residues, it is expected that no (or for ultra-sensitive analytical test methods – very low) detergent levels remain after cleaning. Detergents are not part of the manufacturing process and are only added to facilitate cleaning during the cleaning process. Thus, they should be easily removable. Otherwise, different detergents should be selected.
ADDITIONAL CONSIDERATIONS IN RELATED TO THE CLEANING VALIDATION DESIGN
Recovery of Product and Detergent Residues
Prior to initiating the cleaning validation, you must perform the recovery studies to determine the % of product and detergent that can be collected in your sampling method based on a known amount of product and detergent residues.
Test Until Clean
Testing until clean is a concept utilized by some manufacturers to examine and evaluate the level of testing and the retest results on the early stages of the cleaning process development.
It means to repeat, continue, or prolong the washing or cleaning process with the corresponding testing, resample, and retest equipment or systems until an “acceptable” residue level is attained.
This approach is mostly used during the initial design of the cleaning process and its procedure(s), before initiate the cleaning validation efforts.
For the system or equipment with a validated cleaning process, this practice of resampling should not be utilized and is acceptable only in rare cases.
In this case, constant retesting and resampling demonstrate that the cleaning process is not designed and validated appropriately since these retests actually document the presence of unacceptable residue and contaminants from an ineffective cleaning process.
