1. Why Cosmetic Filling Cleanroom Design Matters

In cosmetic manufacturing, the filling stage is the highest contamination risk point.

Products are exposed to:

• Airborne particles
• Microbial contamination
• Operator contact

Regulatory frameworks such as ISO 22716 and guidelines from the FDA emphasize:

✔ Controlled environment during filling
✔ Clean airflow and pressure control
✔ Hygienic equipment layout

Client Pain Point:
Many factories focus on mixing but underestimate filling contamination risks, leading to product recalls or failed audits.

DERSION Insight:
Filling is where cleanroom design delivers the highest ROI in quality control.

2. Recommended Cleanroom Class for Cosmetic Filling

According to ISO 14644-1:

Standard recommendation:

• Filling Room: ISO Class 7 – 8
• Critical filling points: ISO Class 5 (Laminar Flow optional)

Product-based adjustments:

Client Pain Point:
Overdesign = high cost
Underdesign = contamination risk

DERSION Solution:
✔ Customized ISO level based on product risk
✔ Avoid unnecessary CAPEX

3. HVAC & Airflow Design for Filling Cleanrooms

The success of a filling cleanroom depends heavily on airflow engineering.

Key design parameters:

• HEPA Filtration: H13 / H14
• Air Change Rate:
  • ISO 7 → 30–60 ACH
• Airflow Type:
  • Turbulent (general filling)
  • Laminar (critical zones)
• Pressure:
  • +10–15 Pa (positive pressure)

Client Pain Point:
Unstable airflow → particles fall into open containers

DERSION Advantage:
✔ Precision airflow simulation
✔ Stable pressure cascade system
✔ Energy-efficient HVAC design

4. Cosmetic Filling Cleanroom Layout Design

A well-designed layout ensures both GMP compliance and production efficiency.

Recommended zoning:

1. Material entry buffer
2. Bottle/container preparation area
3. Filling room (core clean zone)
4. Capping & sealing
5. Finished product exit

Key design principles:

• One-way flow (material & personnel)
• Separation of dirty and clean processes
• Minimized operator movement

Client Pain Point:
Poor layout → cross-contamination + low efficiency

DERSION Solution:
✔ Free layout design based on workflow
✔ Industry-specific zoning planning
✔ Turnkey execution

5. Equipment Integration in Filling Cleanrooms

Cleanroom design must match production equipment.

Typical equipment:

• Filling machines
• Capping machines
• Conveyor systems
• Laminar airflow units

Critical requirement:
Airflow must not be disrupted by equipment placement

Client Pain Point:
Many suppliers ignore equipment-airflow interaction

DERSION Strength:
✔ Cleanroom + equipment coordination design
✔ Pre-installation simulation
✔ Reduced commissioning time

6. Construction Materials & Hygiene Design

Requirements:

• Smooth, easy-to-clean surfaces
• No dust accumulation
• Chemical-resistant finishes
• Modular sandwich panels
• Epoxy/PVC flooring
• Rounded corners (no dead zones)

Common solutions:

Client Pain Point:
Cheap materials → cracks, contamination, frequent repairs

DERSION Advantage:
✔ 20,000㎡ smart manufacturing base
✔ High-quality modular systems
✔ Long-term durability

7. Modular Cleanroom: Best Choice for Cosmetic Filling

Modern cosmetic factories increasingly adopt modular cleanrooms.

Benefits:

• Fast installation (2–3 weeks)
• Expandable design
• Lower downtime
• Cost-efficient

DERSION Capabilities:

✔ 20+ years cleanroom experience
✔ 1,000㎡ assembly workshop
✔ CE / ISO / UL certifications
✔ Global turnkey delivery

8. Common Mistakes in Filling Cleanroom Design

❌ Ignoring laminar flow at filling points
❌ Poor personnel flow design
❌ No pressure cascade
❌ Overcrowded equipment layout

Result:

• Product contamination
• Audit failure
• Increased operational cost

9. Recommended Design Configuration

For most cosmetic filling projects:

• Background: ISO 7–8
• Filling point: Laminar flow (ISO 5)
• Pressure: Positive cascade
• HVAC: Stable + energy-efficient

Ensures compliance with:

• ISO 22716
• ISO 14644-1
