With most things they are basically impossible to reverse engineer anything from. Unfortunately formulating a Lignosulphonated chelated micronutrient mix is quite easy. All we are trying to hide is the ratio of actual nutrients which took years to come up with to suit our region and growing conditions.
If anybody was serious they'd simply get hold of a sample, send it to a lab for testing, and off they go
The most useful thing I've used an MSDS was to work out the Ld50 of a certain active to see whether it could be used as an ingredient in an off label mouse/rat bait when bait ran out 3 years ago due to a mouse plague
MSDS's always use mice and rats for toxicity testing
