Any product that goes on your skin must have a label with ingredients.Do all products have it? Most do,
some dont.If a guy walking down the street is selling a cure for baldness and the bottle only says
"baldness cure,rub on head" would you feel safe using it?What if you got sick,who would you call?
MSDS sheets have to be on file for all products if a consumer wants that info.If a person got sick
from using a unmarked product the end result would be a court room.A good lawyer would have
whats called the 82% rule,a basic win 82% of the time.MSDS rules in the workplace are a whole other
matter.Example:You owned a factory and make paint.You must have a sheet on just about everything
in the whole factory.OSHA goes crazy on these rules.The old days are gone.
