1. Three-Way Dispensing Engineering & EU PPWR Recyclability Matrix
| Engineering Criterion | 🏆 Vella Metal-Free Mono-Material PP Airless | Conventional Stainless-Spring Airless (PP / AS / PETG) | Standard Dip-Tube Lotion / Serum Pump (20/410, 24/410) |
|---|---|---|---|
| Spring & Fluid-Path Architecture | 100% All-Plastic Elastomeric PP Spring (Zero Metal Contact) | SUS 304 / 316 stainless spring (often touches formula in cheap pumps) | SUS 304 spring + PE dip tube + glass/steel ball valve |
| Acid / Vitamin C / Retinol Oxidation Risk | 0% Metal-Ion Catalyzed Discoloration · Zero Air Backflow | Risk of rust/yellowing at pH < 3.8 if spring is non-isolated | High oxidation: air enters headspace after every stroke |
| Formula Evacuation Rate & Residual Waste | >98.5% Evacuation (<1.5% residual serum left in bottle) | 95%–98% evacuation | 82%–88% evacuation (12%–18% stranded at bottom corners) |
| Dose Output Precision & Vacuum QC | 0.15 / 0.20 / 0.50 / 1.00 ml ±5% · -0.08 MPa Leak Tested | 0.20–1.00 ml ±8% · 1,500-stroke actuator fatigue tested | 0.20–2.00 ml · Fails inverted dispensing |
| EU PPWR Recyclability & Vella Pilot MOQ | 100% Single-Stream PP Recyclable · 1,000 Stock / 3,000 Custom | Requires destructive disassembly to remove metal spring | Mixed material stream (glass + PP + metal spring + PE tube) |
