1. Facility & Layout: Semi-Solid Manufacturing Zone

The Taj Pharma OSD & External Preparation Plant features a meticulously designed semi-solid manufacturing area, engineered to meet global GMP guidelines (WHO, PICS, EU-GMP, and USFDA compliance-ready) with advanced infrastructure aimed at ensuring product quality, safety, and regulatory compliance.


A. Dedicated Semi-Solid Area

  • Segregated Processing Block
    The semi-solid manufacturing block is physically separated from solid dosage (tablets/capsules) and sterile manufacturing zones, both structurally and via dedicated HVAC and personnel/material movement routes.
  • Unidirectional Flow
    Clear segregation of raw material entry, processing, and dispatch ensures unidirectional flow of personnel and materials, minimizing contamination risks.
  • Airlocks & Interlocks
    Access to the semi-solid area is controlled via personnel airlocks (PALs) and material airlocks (MALs) with interlocked doors to preserve differential pressure and cleanliness standards.
  • Gowning Zones
    Multiple-stage gowning rooms with classified entry systems allow for proper donning of sterile PPE, as per WHO-GMP Annex 1 & 6 recommendations.

B. Zoned HVAC System (HEPA-Filtered)

  • Zonal Classification
    The semi-solid area is divided into classified zones based on activity:
    • Dispensing – ISO 8 (Class 100,000)
    • Manufacturing (Mixing & Emulsification) – ISO 8
    • Filling & Sealing – ISO 7 or higher (Class 10,000 or better), where product exposure risk is highest.
    • Secondary Packing – Unclassified or ISO 9, as applicable
  • HEPA Filtration
    • All critical zones (filling, emulsification) use HEPA filters (≥99.97% efficiency at 0.3 µm).
    • Air changes per hour (ACPH): 20–40 for ISO 8 areas, ≥60 for ISO 7.
  • Pressure Differentials
    • Maintained at ≥15 Pascals between cleaner and less clean areas.
    • Pressure cascade prevents ingress of unfiltered air into controlled zones.
  • Temperature & Humidity Control
    • Maintained at 22±2°C and relative humidity 45–55%, unless product-specific conditions demand otherwise.
  • Monitoring & Validation
    • HVAC system is monitored via Building Management System (BMS).
    • Particulate monitoring, differential pressure, temperature, humidity, and microbial load data are recorded in real-time.

C. ISO Class 100,000 (ISO 8) Manufacturing Environment

  • Cleanroom Design
    • All manufacturing operations take place in an ISO 8 cleanroom environment compliant with EU GMP Annex 1 and WHO TRS 961.
    • Filling and primary packaging zones are ISO 7 or restricted-access barrier system (RABS) equipped, depending on product sensitivity.
  • Airflow Patterns
    • Designed with laminar flow modules over critical work areas, ensuring low turbulence and directional airflow away from the product.
  • Cleanroom Garments
    • Operators wear lint-free garments, sterile gloves, hair and beard covers, and antistatic footwear, regularly laundered and sterilized.

D. Epoxy-Coated Walls & Floors

  • Construction Material Standards
    • Walls and ceilings are made of modular sandwich panels (SS304 or coated GI).
    • All corners are coved (rounded) to prevent dust accumulation and facilitate easy cleaning.
  • Flooring
    • High-grade epoxy resin flooring provides:
      • Seamless, non-porous, anti-microbial surface
      • Chemical and abrasion resistance
      • Easy decontamination using standard disinfectants (e.g., IPA, QAC)
  • Cleaning Validation

3. Technical Manufacturing Steps: Creams & Ointments

Each step in the semi-solid production process is governed by Standard Operating Procedures (SOPs), Master Formula Records (MFRs), and validated Batch Manufacturing Records (BMRs) to ensure product consistency, compliance, and traceability.


A. Weighing & Dispensing

Location:

  • Dedicated Class D (ISO 8) dispensing area with segregated zones for active and excipient materials.

Process Details:

  • Materials are weighed individually as per the MFR using calibrated digital load cells/balances (with certifications traceable to NABL or equivalent).

    • Expiry/Re-test dates

Documentation:

  • BMR entries made in real-time or electronically (e-BMR), with deviation logs and supervisory approvals.

B. Phase Preparation

Purpose:
To prepare oil-based and water-based components separately in accordance with the formulation design.

Oil Phase:

  • Waxes, emulsifiers, lipophilic APIs/excipients are heated in SS316L jacketed vessels.
  • Target temperature: Usually 60–80°C, depending on formulation; maintained within ±1°C tolerance.
  • Agitators are used to prevent localized overheating.

Aqueous Phase:

  • Hydrophilic components, buffers, preservatives, and water-soluble APIs are dissolved under agitation.

C. Emulsification & Mixing

Objective:
To combine oil and water phases into a stable emulsion and initiate dispersion of any suspended actives.

Process Flow:

  • Oil phase is slowly added to the aqueous phase (or vice versa based on emulsion type: O/W or W/O).
  • Contra Rotary Mixer / Planetary Mixer (Vacuum type) is used.
  • Continuous agitation under vacuum prevents air entrapment and ensures microbial control.

Key Parameters:

  • Viscosity increases as the emulsion cools, forming the final cream/ointment base.

Final Homogenization:

  • Optional final pass through inline homogenizer or colloid mill for texture refinement.
  • Ensures final batch is uniform, glossy, and smooth in appearance.

Sampling Points:

  • Final bulk sampled for pH, viscosity, emulsion stability, and microbiological testing.
