• Preservative in acidic foods & beverages: syrups, soft
drinks, sauces, pickles (synergy with sorbates and mild
heat). • Technical: corrosion inhibitor in coolants; latex & adhesive preservation; industrial formulations. |
• 25 kg PP bags with PE liner • 500–1000 kg FIBC. • Custom fine‑granular, dust‑reduced options for beverage plants. |
• Non‑DG. Keep dry and sealed; hygroscopic. Avoid strong
acids (liberates benzoic acid) and oxidizers.
• Use food‑contact compliant packaging for FCC/USP/EP grade. Follow GMP and local additive limits. • Compatible: HDPE/PP/SS. Avoid moisture ingress to prevent caking. |
