Standard Operating Procedure for Quality Control Testing of Gels
1) Purpose
The purpose of this SOP is to define the procedures for performing quality control (QC) testing of gels to ensure they meet the required standards for safety, efficacy, and quality.
2) Scope
This SOP applies to all QC personnel involved in the testing of gels manufactured in the pharmaceutical production facility.
3) Responsibilities
Quality Control Manager: Oversee the QC testing process and ensure compliance with this SOP.
QC Analysts: Conduct the QC tests as per the procedures outlined in this SOP.
Production Staff: Provide necessary samples and support to the QC department for testing.
4) Procedure
4.1 Sample Collection
4.1.1 Collect gel samples from different batches as per the sampling plan.
4.1.2 Ensure samples are labeled correctly with batch number, date, and other relevant details.
4.2 Physical Testing
4.2.1 Appearance: Examine the gel for color, consistency, and homogeneity.
4.2.2 pH: Measure the pH of the gel using a calibrated pH meter.
4.2.3 Viscosity: Measure the viscosity using a viscometer as per the standard method.
4.3 Chemical Testing
4.3.1 Assay of Active Ingredient: Determine the concentration of the active ingredient using validated analytical methods (e.g., HPLC).
4.3.2 Preservative Content: Quantify the preservative content as per the specified method.
4.4 Microbial Testing
4.4.1 Total Aerobic Microbial Count (TAMC): Perform microbial testing to determine TAMC.
4.4.2 Total Yeast and Mold Count (TYMC): Conduct tests to determine TYMC.
4.4.3 Pathogen Testing: Test for specific pathogens such as E. coli, S. aureus, and P. aeruginosa.
4.5 Stability Testing
4.5.1 Conduct stability testing under specified conditions (e.g., temperature, humidity) to assess the gel’s shelf-life.
4.5.2 Record and analyze stability data at predefined intervals.
4.6 Documentation and Reporting
