Elixir Department: SOP for CIP Validation of Mixing Equipment – V 2.0

Standard Operating Procedure for CIP Validation of Mixing Equipment in Elixir Manufacturing

Department Elixir Department
SOP No. SOP/ELX/165/2025
Supersedes SOP/ELX/165/2022
Page No. Page 1 of 11
Issue Date 11/04/2025
Effective Date 15/04/2025
Review Date 11/04/2026

1. Purpose

To define the procedure for validating the Clean-In-Place (CIP) system used in the cleaning of mixing equipment in the Elixir Department, ensuring that the cleaning process consistently removes product residues, contaminants, and cleaning agents to a validated level.

2. Scope

This SOP applies to all mixing vessels, tanks, and associated pipelines equipped with automated or semi-automated CIP systems used in elixir manufacturing operations.

3. Responsibilities

  • Validation Team:
    • Prepare and execute the CIP validation protocol and report.
    • Review analytical results and determine acceptance.
  • Production Department:
    • Support execution of the CIP cycle as per protocol.
    • Ensure timely coordination for sampling.
  • QA Department:
    • Approve validation protocol and monitor compliance.
    • Review and approve final validation reports.

4. Accountability

The Validation Manager is accountable for the execution and documentation of CIP validation. QA Head ensures regulatory compliance and final approval. The Production Head is responsible for operational readiness.

5. Procedure

5.1 Preparation of Validation Protocol

  1. Define equipment to be validated (e.g., MXR-ELX-01).
  2. List critical parameters to be controlled:
    • Detergent concentration
    • Flow rate
    • Temperature
    • Cycle duration
    • Rinse effectiveness
  3. Determine sampling locations based on worst-case points (e.g., spray balls, bottom outlet, corners).

5.2 Execution of CIP Cycle

  1. Ensure system readiness and calibrate flowmeters and temperature gauges.
  2. Run CIP cycle as per standard recipe:
    • Pre-rinse with purified water – 5 minutes
    • Detergent wash (1% solution at 45–50°C) – 10 minutes
    • Intermediate rinse – 5 minutes
    • Final rinse with hot purified water (60–80°C) – 5 minutes
  3. Document the cycle parameters in the CIP Validation Logbook (Annexure-1).

5.3 Sampling and Testing

  1. Collect rinse samples post-final rinse at predefined locations.
  2. Perform swab sampling from hard-to-clean areas.
  3. Test for:
    • Product residue (UV/vis spectrophotometry or HPLC)
    • Detergent residue (TOC or conductivity)
    • Microbial contamination (TVC, absence of pathogens)
  4. Record all results and compare with acceptance criteria defined in the protocol.

5.4 Repetition and Consistency

  1. Repeat the validation run for three consecutive successful cleaning cycles.
  2. Ensure consistent results across all runs and locations.

5.5 Final Report and Approval

  1. Compile and review all data, deviations, and observations.
  2. Validation Team drafts the final CIP validation report.
  3. QA reviews and approves the report.
  4. Validated status shall be recorded on equipment status label.
