FAQ - SoftAcid
What is SoftAcid?
SoftAcid is a patented mixture of organic acids and modified and functionalized lignosulfonic acid, which moderates the aggressiveness of the organic acids, hence the name Soft.
What is lignosulphonic acid?
It is a Biopolymer from wood.
How can SoftAcid reduce corrosivity?
Adding a few per cent of lignosulphonic acid to strong acids clearly reduces the corrosion of the mixture relative to the pure acids. Lignosulphonic acid is a surface active compound that will adsorb onto many surfaces. The negatively charged lignosulphonic acid will readily adsorb onto positively charged surfaces. In the presence of divalent or trivalent cations lignosulphonic acid will also adsorb onto negatively charged surfaces. The cations can be supplied from the oxide layer covering many metal surfaces. (B. O. Myrvold, Journal of Power Sources, 117 (2003) 187-202). Lignosulphonic acid adsorbed to the surface might form a physical barrier that prevents the acid from reaching the surface, and thus reduces the corrosion.
The high molecular weight lignosulphonic acid will not penetrate skin. Also on skin it might thus form a barrier.
Is SoftAcid really an acid blend or is it a kind of buffer?
It is absolutely not a buffer. Corrosivity of the pure organic acids is reduced by adding another acid, lignosulphonic acid. Hence, SoftAcid has a very low pH and thus is very effective
Why use SoftAcid in drinking water instead of chlorine or any other acid blend?
SoftAcid can remove the biofilm from your pipes. It is the only product on the market that can both clean pipes from the biofilm and acidify your drinking water to secure the animal digestive tracts.
I am using some probiotics in silage, what would be the advantages of using SoftAcid instead?
Probiotics are usually very efficient under ideal conditions. However, as soon as the dry matter is out of range or if the weather is not good, probiotics will not work. With SoftAcid, it comes down to chemistry - and you will always get what you pay for.
Is SoftAcid classified as Dangerous?
No, most SoftAcid products are classified as irritant, and thus are not dangerous. Pure organic acids are classified as corrosive.
I am using formaldehyde to get rid of salmonella, why should I switch to SoftAcid?
Formaldehyde is a dangerous and carcinogenic product. In a number of trials in Spain and Brazil we have shown that SoftAcid can replace formaldehyde without any loss of efficiency.
What are the advised inclusion rates for SoftAcid?
In animal feed from 2 Kg/T (broiler, layers, pig finishers) to 6Kg/T (piglets).
In drinking water, a pH of 3,8 is a common target. This is generally achieved with 0,05 to 0,2% of SoftAcid.
For silage preservation, around 5kg/T is used in most countries
For grain preservation, SoftAcid is normally dosed at 1 to 2kg/T
