I am by no means an expert on defoamers. I do know that there are two ways to extract oil from a plant. One is by expeller extraction(squeezing oil out of plant). The other is by chemical extraction which produces hexane. The canola oil we use is expeller extacted, which does not involve use of chemicals. We started using this type of defoamer because it was recommended by organic certifier.
