I think it is very wise of Dharma to have that info available.
I did scan the MSDS for procion MX dyes specifically, since I have some of Dharma's own brand of dye and some from Jacquard, and I'm not seeing the ones for Jacquard, but it's early, my kid is on my lap, and I don't have my glasses on. :-) I'll have to get back to it later. Thanks for posting the link. :-)
