I've seen tons of MSDSs that are basically useless smokescreens.
While the manufacturers / suppliers are supposed to fill out the forms completely (for obvious reasons), there is no regulatory body with "teeth" actually reviewing them. So some are nigh on to useless.
Which is bad for the folks that dcan't look at the sheet and see that it is a whitewashing job.
My favorite is the "its safe" kind of thing on something that containes finely ground flint. Yeah, it is safe........ when it is WET. That is the kind of technicalities they often try to play.
Years ago I had a health issue from using lusters (final working diagnosis... that was the source of the problem). The carriers from the particular supplier were listed as something like "organic hydrocarbons". Long story short, my doctors (and I) would have needed a bevy of lawyers to pry WHAT exact stuff those were. We gave up.
The "stock" bevy of usual suspenders / binders / brushing consistency additives for water based are ball clays, CMC, bentonite, hectorite, macaloid, gum arabic, gum tragecanth, polyvinyl acetate, propelyne glycol, glycerine, green tea extract, and various Ph adjusters for the water chemistry. And formaldehyde or other mold inhibitors to keep the organic additives from "growing".
