Luprosil®

Feed preservation and silage making with BASF´s organic acids

With organic acids from BASF, protecting the quality of your feed is safe and easy as these acids take their potency from nature’s realm.

Propionic acid and formic acid, the liquid starting materials for our Luprosil® and Amasil® product lines, occur in plants, in silage and even in foods. As natural preservatives, these organic acids are completely metabolized. Using Luprosil® and Amasil®, we therefore combat the dangers of feed contamination and loss by perfecting what nature already has to offer.

BASF has been working with Luprosil® propionic acid and Amasil® formic acid for decades in an effort to produce the best feed for your animals and your budget. Luprosil® is traditionally known for its preservative and mold-inhibiting properties. Amasil® in its purest form has a strong acidifying effect and pronounced antimicrobial efficacy. It is also a powerful weapon in the fight against pathogens such as salmonella and E. coli.

Why to choose Luprosil®?

Pure organic acids such as propionic acid and formic acid are widely used for feed preservation in the form of liquid acids under the trade names Luprosil® and Amasil®. Both products are efficient to use, but they require high-quality equipment and careful work-safety measures for their use because they are corrosive. In the past we therefore recommended the use of Luprosil® propionic acid (99,5 %), instead of the more complex formic acid.
