Frequently asked questions
How should BKC 80% be stored?+
Store in sealed HDPE drums at 15–40 °C, away from direct sunlight. Below ~15 °C it can gel; warm gently to restore a pourable liquid.
Is BKC 80% more hazardous than BKC 50%?+
It carries the same GHS classification (GHS05/07/09, Danger) but is more concentrated, so handle with full PPE and dilute carefully.
Do you provide COA, SDS and pharmacopoeia documentation?+
Yes — batch COA, GHS SDS and TDS with every order; USP/BP/EP/IP documentation and GMP/Halal certificates on request.
