EVOH (Ethylene Vinyl Alcohol) is a high-performance barrier material used in cosmetic tubes to prevent oxygen, moisture, and light from degrading sensitive formulas. It is typically layered inside multi-layer tubes such as ABL or PBL tubes, keeping creams, lotions, and sunscreens stable over time.
Why EVOH Is Important
- Protects active ingredients from oxidation and spoilage
- Prevents moisture loss and formula separation
- Maintains product color, fragrance, and texture
- Works inside laminated tubes without contacting the product directly
- Compatible with PE, PCR, and other plastic layers
Typical EVOH Tube Structures
| Tube Type | Layers | Barrier Function |
|---|---|---|
| ABL Tube | 3–5 Layers | EVOH prevents oxygen and moisture ingress |
| PBL Tube | 3–5 Layers | EVOH layer protects sensitive formulas |
| Airless Pump Tube | Multi-layer | EVOH combined with PE layers extends shelf life |
