How to evaluate Span 80
- Run it in parallel against your current product in your own formulation — we suggest a 2–3 route comparison.
- Check emulsion stability, dilution behaviour, storage, foam and application-specific performance.
- Request TDS, SDS and recent-batch COA before testing; batch traceability is provided for every shipment.
