SoftAcid IV+S
SoftAcid IV+ S is a patented mixture of formic and propionic acid and modified lignosulphonic acids. This special combination considerably reduces the aggressiveness of formic and propionic acid.
In comparison with purely organic acids, SoftAcid IV+ S is only slightly corrosive and does not cause chemical burns in case of contact with the skin. SoftAcid IV+ S is not classified as a hazardous material.

Experiments in the Landwirtschaftszentrum (Agricultural Centre) Haus Riswick of the Landwirtschaftskammer Nordrhein-Westfalen (Chamber of Agriculture of North Rhine-Westphalia) have shown that the aerobic stability of CCM more than doubles in comparison with untreated CCM when SoftAcid IV+ S is used.
SoftAcid IV+S for the preservation of CCM bears the quality seal for ensilage agents of the DLG (German Agricultural Association).
Advantages of SoftAcid IV+ S:
- Clear improvement of the aerobic stability
- Very good inhibition of lactate-degrading yeasts and moulds
- 95% less corrosive than purely organic acids
- Good taste
- Does not cause chemical burns
- Not a hazardous material
- Less wear in warehouses, dosing and mixing plants, and stall equipment
- Improvement of the working conditions for grain preservation
Recommended Dosage
For the improvement of the aerobic stability of CCM, we recommend the following dosage:
Application rate: 0.4 – 0.6 %
Density (20°C): 1.15 g/cm3
