36.1.1 Objective

The objective of this protocol is to demonstrate that the cleaning procedure will successfully and consistently reduce the level of residues to a predetermined level of acceptability for the 1000-L manufacturing vessel.

36.1.2 Scope

This protocol will cover cleaning of the semisolid manufacturing vessel (Figure 36.1.1) for the following cream and ointment products (Table 36.1.1).

The above-mentioned products are divided into different categories (group) based on water solubility, toxicity, and batch size. From each group, one worst-case products analyzed for cleaning validation (Table 36.1.2).

Since a natural herb is manufactured in both ointment and cream forms, the cleaning procedure for the ointment is deemed sufficient to meet the criteria for both the dosage forms due to more difficult cleaning of the oily product (ointment).

Based on the criteria mentioned above, selection of natural herb ointment and oxytetra-cycline ointment as worst cases for less solubility and high toxicity, respectively, will also validate the cleaning procedure for cream products. However, to further enhance the

confidence, a high toxicity worst case is selected in cream products as well. Diclofenac sodium cream is most toxic (diclofenac sodium) in all the cream products; therefore, this product will be taken as another worst case for cleaning procedure validation.

Large batch size is also covered in the natural herbs ointment validation, which is 1000 kg; therefore a separate case of largest batch size will not be taken for validation.

The following personnel are responsible for the execution of this protocol:

4. Start the agitator and homogenizer at speed II, with recirculation

5. Continue mixing and homogenizing for a further 20 min after reaching 90°C

6. Connect the outlet valve of the vessel with a hose and drain out the washing in a 200-L stainless steel drum

7. Lift the vessel lid and clean thoroughly the agitator angles and the lower side of the lid with a sponge

8. Rinse the inside and the lower side of the lid of the vessel with purified water for 3 min by means of a 1" hose

9. Drain out the water in the drainage by means of a hose

10. Dismantle all the joints, valves, and pipes

11. Clean all joints, valves, and pipes with sponge wetted with 1% soap

12. Flush each part with purified water by means of a 1" hose for 30 s

13. Spray the inside and outside of the vessel with 70% alcohol

14. Label the vessel "Clean"

15. Make entries in the cleaning log and label the equipment "Clean" with the date of cleaning and signature of the supervisor as per SOP No. ABC-002

36.1.6 Description of the Sampling Process 36.1.6.1 Sampling Technique

The following sampling techniques are used to take the sample from the vessel:

a. Surface swabs (sterile cotton swabs wetted with purified water)

b. Water rinses (in clean bottle as listed below)

36.1.6.1.1 Surface Swabs

36.1.6.1.1.1 Procedure for Sampling

Sampling should be performed as per SOP No. ABC-003; the validation officer is responsible for taking the swab sample. Samples of the internal surfaces are taken by moistening the swab (ready-made sterile cotton swab) with a suitable solvent (purified water). Sample a 25-cm2 area and place the swab in a test tube containing 10 mL of solvent (purified water). Swab sample from each part of manufacturing vessel is collected as per Table 36.1.4.

36.1.6.1.1.2 Sampling Precautions Before taking the sample, wear i. Hand gloves ii. Face mask

36.1.6.1.1.3 Rinse Sample

The rinse sampling technique is used to take samples from the vessel. After the completion of cleaning, take rinse samples from the bottom of the vessel sampling points (Figure 36.1.4) R1-R5 for the chemical analysis and R6 for bio-burden (Table 36.1.5).

36.1.6.1.1.4 Handling of Samples

Samples are kept in the refrigerator if not testing immediately

Analyze the samples within 2 h after collection for pH, conductivity, and TOC and detergent detection

v. The final report for cleaning validation should be prepared by the validation officer.

36.1.10 Acceptance Criteria a. Visual inspection: The visible internal equipment surfaces and all critical and difficult-to-clean parts are optically free from residue and the color of the final rinse water is comparable to DIW.

b. pH determination: The pH value of the rinse should be in between 5 and 7 and comparable to DIW pH value.

c. Conductivity: The conductivity of the rinse should not be more than the conductivity of the blank DIW sample kept under the same conditions.

d. Total organic carbon: The TOC of the final rinse should be comparable to the blank DIW sample kept under the same conditions (DIW TOC limit is NMT 500 ppb).

e. Detergent detection: No foam is detected on top of the rinse sample after testing.

f. Maximum allowable carryover: The active ingredient in the final rinse is either not detected or is equal to or less than the MAC (calculated theoretically for product).

Based on the solubility and maximum daily dose matrix, the MAC is calculated for each product. The MAC is calculated as follows:

MAC _ TDx BS x SF MAC _ LDD , where MAC is the maximum allowable carryover, TD is a single therapeutic dose, BS is the batch size of the next product to be manufactured in the same equipment, SF is the safety factor, and LDD is the largest daily dose of the next product to be manufactured in the same equipment.

The calculated value is the maximum amount of active ingredient of a certain product that is allowed to be carried over to the next batch.

g. Bio-burden: The bio-burden should not be more than 10 cfu/100 mL for the rinses.
