Formic Acid 85% Feed Grade
CAS Number: 64-18-6
Formic Acid 85% is the strongest organic acid used in animal feed preservation, effective against gram-negative bacteria including Salmonella and E. coli due to its low molecular weight and high membrane permeability. It is widely used as a silage preservative and feed acidifier in both liquid and coated solid forms. Our product is manufactured to feed-grade purity standards with consistent concentration for reliable antimicrobial dosing.

Applications
- Liquid feed acidification for swine operations to reduce Salmonella risk
- Silage preservation to inhibit clostridial spoilage fermentation
- Grain preservative blended with propionic acid to prevent mould growth
- Piglet feeds as an acidifier to support gastric acid function post-weaning
- Poultry drinking water acidification to reduce pathogen load
Key Features
- Strongest organic acid with lowest pKa providing maximum antimicrobial effect
- Effective against Salmonella and E. coli at lower inclusion rates than acetic acid
- Reduces feed pH rapidly making it ideal for liquid feed systems
- Can be blended with propionic acid for broad-spectrum preservation
