From what I read on a house cleaning forum, you can't always trust the MSDS. For example, they aren't required to list ALL ingredients, only those that could be seen as corrosive, explosive, combustible, or "dangerous" (sum it all up into one) in nature.
Which is why many MSDS will not list "Water".....even though they may in fact contain water.
They can use "water" to "fill in the gaps" between the percentages. Since I've noticed more and more MSDS using percentages, i.e.
5-10%
25-35%
etc....
Making it a "guess" as to the exact concoction.
Perhaps it was showing the amines are not "dangerous" and some authoriative figure has allowed them to "hide" the ingredient from the MSDS.....same deal with how some MSDS will use "Proprietary Ingredient" or "Trade-secret"
I think I saw one and/or both of those references on some STP product MSDS.....heh. Where generally the "proprietary" % is in the 5-15% range.
I think it was actually the Gas Treatment, or something....and Kerosene was the "primary" ingredient. But as mentioned earlier, oils, water, kerosene, etc. are used as "carriers" to get the product where it needs to go.
BTW, on a similar(sort of unrelated...but I see it's rising effects in the auto field) note, is anyone else peeved about these "2x concentrate products"? lol....I HATE the concentrated wash detergents...if anything, they just make them more "syrupy" so it's harder to accurately measure the dose from the bottle, to the measuring cup. Well, that's easy, the hard part is getting the measured soap out of the measuring cup lol, it's all syrup-like, and stuck up on the sides....
I read all the hype, I know it's to make packaging smaller, but then you gotta wait 5 minutes for the "dose" to pour out of the cap into the wash machine.
Thinking the affects may be similar with the new smaller (2 fl. oz. if I recall correctly?) Prestone products? Their gas treatment, Fuel Injector/Carb Cleaner, and Octane Booster are now in 2 oz. bottles....haven't tried them, but they gotta have "something" in there to "keep the flow" if you know what I mean.
