Where I find this can be fun is that different countries seem to have different requirements for precision. Or just straight up different formulations for the same thing.

German wd40 says it’s all c9-c11 carbon chains:

US has a CARB and non-CARB formulation which are also different:

I wonder how many different chemicals can be described as ‘c9-c11’ chains. Thousands?

Yes but I doubt the manufacturer is consistent with how much of each is in there either
