8.0 METHODOLOGY OF CLEANING PROCESS VALIDATION

When the process is completed then note the time and date step wise. Record the start of un cleaned hold time, after 30 hrs note the time with date for evaluation of un-cleaned hold time.
After 30 hr take swab and rinse sample for microbial evaluation as per respective SOP QM-047-02
Take the sample for un-cleaned hold time as per sampling plan given at page no. 30.
Clean all equipments as per respective SOP for all equipment given at point no. 7.2
Initially take the microbial swab as point no. 8.7 then Take rinse sample for chemical analysis as per point no. 8.8
After collection of samples hold all equipments and accessories for 72 hrs. After 72 hrs again collect the samples of all equipments and accessories as per sampling plan . After 72 hr. note the time and date as per sampling plan for evaluation of cleaned equipment hold time. First take swab sample for microbiology, then chemical rinse. Send these samples to QC for analysis.
Sample shall be taken from hardest to clean surface of the equipment(i.e Dead legs, Dead spots).
Continue the above procedure for another two batches.

For microbial: For Information for rinse sample and swab sample.

8.3 Maximum Allowable Carryover:
Cleaning Limits Selection Criteria based on Maximum Allowable Carryover (MAC) :

8.3.1 MAC Based on 0.1 % Safety Factor

MAC = Lowest daily dose (mg) x Lowest B.Size (Kg) x 1000000
Largest Daily Dose (mg) x 1000

8.3.2 MAC based on 10 ppm = 0.00001mg

= 10 ppm x B.Size
= 0.00001 x 1808 x 1000000 = 18080 mg
Based on above criteria 1468 mg is the lowest value, hence it is consider as acceptance criteria.

8.3.3 MAC for each square inch.

MAC value =
Total surface area
(Equipments)

8.3.4 MAC for swab sample.



Surface area for swab sample 5”x 5” .
Total surface area in swab sample = 5 x5= 25 square inch.
MAC for each swab = MAC for each square inch x total surface area of swab
= 0.44 x 25 = 11 mg/swab
MAC for each swab = 11 mg/swab = NMT 1100µg/swab
8.3.5 MAC for rinse sample of each equipment.
