hey,,sorry to bother you with a little information,,,ok,,we do cleaning as per cleaning SOP's of each equipments going through the process of making vitmain syrups,,as one equipment is tank,so,we rinse it water first,then with detergent(we have three class of detergents,Class A,B,C).then again with water twice,and during all this sample are collected every 15 minutes until no residue is detected.this detection is done by QC personnel,,after when QC gives a green signal to the production that its free from residue(checked by assay for all vitamins), Sainitization phase is proceeded i.e rinse with 70% alcohol.and then final rinsing with deionzed water and QC/QA perssnl inspetc tanks,and take samples from most undesirble places and go for chemical and microbiological testings. when QC informs there is no residue of alcohol or other stuffs.and tanks is sealed for the time being microbial results come by.
now my questions is when this calculation of MACO or LD50 or toxicological limits are applied and how..we just follow 10 ppm cretria,,we dont have structure to justify the limits we have created for acceptance criteria. and on which ever site i have seen,,they are giving protocols for API only,,how i put the MACO calucltn for liquid formualtions?
