Apples and oranges - how to judge your mold inhibitor

Do you know how much value you get for your investment in mold inhibitors? Comparing different mold inhibitors can be difficult. But a few simple pointers can make it a lot easier.

1) Type and concentration of active ingredients; propionic acid is known for its mold inhibiting properties: higher level usually indicate higher mold inhibiting properties per liter.

2) Buffering; to reduce the corrosive properties many products are buffered with ammonia or contain esters of organic acids.

3) Carrier; in general it means a dilution of active ingredients to change the physical properties of the product.

4) The application costs; take the dosage rate and price in consideration.

Especially buffering and concentration do not work together well. Buffered is safer for man and machinery but in the case of ammonia can come at the expense of propionic acid levels. Products that use esters of organic acids such as ProSid™ MI 700 can keep the propionic acid levels up and also be non-ADR.
