Cleaning Validation Sal Acid & Menthol
I am working on 2 cleaning validations for Salicylic Acid and Menthol and am having a hard time determining what to use on some swabs to see if the actives are still in the tank. It looks like both Sal Acid and Menthol in Alcohol and Acetone so I am thinking I can use one of those materials on the swabs to then see if the tank is clean. Is there a better option?
