The post-CLP mold inhibition landscape
The post-CLP mold inhibition landscape
The mold inhibition landscape is experiencing some radical changes. Many end-user of organic acid based mold inhibitors or preservatives will no longer be allowed to use the product that they have been working with in the past. On June 1 we will enter the last phase of CLP implementation. This reclassification of all preparations means that a high percentage of the mold inhibitors that are available on the market today will become classified as ADR Dangerous Goods with regard to transportation and corrosive with regard to handling of the products. Of course suppliers of acid-based preservatives haven’t been sitting still since the new legislation was announced. Let’s have a look at today’s mold inhibitor landscape to shed some light on the situation and the alternatives that are available.
A common way to buffer organic acid based mold inhibitors in the past was to use ammonium for buffering. Corrosion tests have shown that many ammonium buffered products will become ADR after the reclassification due to its corrosive effect on steel. We have identified 2 routs to creating mold inhibitors that will still be considered non-Dangerous Goods and non-corrosive after June 1:
• Using glycerol esters of propionic acid.
• Using sodium formate or other sodium solutions for their buffering effect.
The glycerol ester route: mold inhibition at its finest
Propionic acid is at the core of virtually every established mold inhibitor for grains in the market. Esterifying propionic acid with glycerol creates a molecule that is non-corrosive and that removes the pungent smell of propionic acid with great reliability. Glycerol esters of propionic acid have less evaporation compared to pure propionic acid. This ensures a long-lasting effect of the product in your grains during storage.
Prosid™ MI 700 is our patented one of a kind preservative for grain and feed that uses esterified propionic acid. This product has some of the best features available on the market and a density that is nearly the same as that of propionic acid, meaning that you can expect to dose the same liters without changing the settings on your dosage equipment.
Sodium buffering: the economic alternative
Buffering mold inhibitors with sodium is not a new concept. We have reviewed our portfolio of mold inhibitors based on sodium buffering to find the best solutions that meet the stricter CLP criteria for corrosion and safety. Sodium buffering allows for the creation of products that are effective and safe to handle. Our liquid buffered ProSid™ MI product portfolio offers highly concentrated and semi-concentrated products.
Preserving grain with a buffered liquid product is an efficient way to protect your grain from molds and yeast and to minimize the risk of aflatoxin-formation. There are also non-corrosive dry mold inhibitors in the ProSid™ MI portfolio, which are easy to mix with feed or grain and that you can easily use with your existing mixer.
