Plant oils rich in omega-3 and polyunsaturated fatty acids are sensitive to oxidation. Vultifrine is no exception: its active compounds (polyphenols, omega-3/omega-6, tocopherols) degrade when exposed to light, heat and oxygen. Proper storage is essential to maintain its efficacy throughout use.
Shelf life · Time zones
1 min| Period | Status | Quality | Recommendation |
|---|---|---|---|
| 0-12 months after opening | Optimal zone | All active properties intact | Ideal use · full efficacy |
| 12-18 months after opening | Acceptable zone | Slight reduction in actives | Usable if smell and colour normal |
| Beyond 18 months | To discard | Risk of rancidity | Discard even without obvious signs |
| Unopened (manufacturer DLU) | Up to 24 months | Preserved actives | Respect the expiry date |
Optimal storage conditions
1 minMaximum 25 degrees C. Beyond this, oxidation accelerates. No sudden temperature variations. A cool, stable cupboard is ideal.
Total protection from direct light and UV. Amber glass filters part of it · do not leave in full sunlight or near a window.
Bathroom not recommended · alternating heat and humidity after showering degrade the lipids. Prefer a bedroom or medicine cabinet.
Oxygen is the main enemy of polyunsaturated fatty acids. Close the stopper immediately after each use. Check the pump seal if applicable.
Signs of rancidity to watch for
1 min- Rancid or "crayon" smell: main sign of lipid oxidation · discard immediately
- Progressive browning: oxidised polyphenols change colour · discard
- Persistent flaky deposit: sign of polymerisation or microbial contamination
- Normal appearance: slightly amber, clear or slightly cloudy, neutral plant smell
- Refrigerator: optional, prolongs shelf life but requires return to room temperature before use
Packaging and format advice
1 min- Prefer amber glass bottle with pump or pipette stopper
- 50ml format: ideal · used within 12-18 months without risk

Frequently asked questions
1 min12 to 18 months after opening in optimal conditions (15-20 degrees C, away from light, sealed). Beyond 18 months, discard even without obvious signs of rancidity.
Not recommended. Alternating heat and humidity from showering accelerate lipid oxidation. Prefer a bedroom cupboard or medicine cabinet at a stable temperature below 25 degrees C.
3 main signs: rancid or "crayon" smell (main indicator), progressive browning of the oil, persistent flaky deposit. Discard at any of these signs, even before the expiry date.
Yes, the refrigerator prolongs shelf life but is not mandatory. Let the oil return to room temperature before each use (15-20 minutes). Avoid repeated thermal shocks.
