How should I evaluate samples and do you support stability testing?
Evaluate aroma, appearance, pH and formulation compatibility on arrival; we support further stability testing on request.
| Evaluation Step | What to Check |
|---|---|
| Aroma | Intensity, freshness, depth vs your brief |
| Appearance | Clarity, color, absence of sediment |
| pH & SG | Match COA values |
| Formulation test | Miscibility in your base formula |
| Skin test | Patch test on target users |
- Accelerated stability (40°C / 75% RH, 3 months)
- Freeze–thaw cycles (5 cycles)
- Long-term stability (25°C, 12 months)
- Formula compatibility report with your base
Samples from the actual production batch ensure your evaluation matches bulk supply. Share your test protocol — we can run or coordinate stability testing with certified labs.
