Sodium Silicate is nasty in liquid form, worse when vaporized. It's referred to as liquid glass. However, once the car engine is run, the water portion is going to evaporate off, leaving a very base PH crusty residue in the engine. It's not particularly scary in that form, unless you reconsitute it with water again. At that point, it's main issue as a polutuant is that it has a very base PH, and is still water-soluable. Sort of like an abrasive Draino.
It's generally neutralized with a weak acetic acid solution. Mix the right base and the right acid in the right quantities and you have neutral ph sand.
Ever have a wacky high school science teacher who would awe the students by using hydrocloric acid strong enough to disolve nuts and bolts as mouth wash, after he mixed something baking soda into it? Mix the right base and the right acid, in the right ratios, and you get the same PH as water. Don't drink, ad Do Not Try This at Home!
We worked with less dangerous chemicals in the marine industry accidents and down the road illnesses did and still do happen. If the rings are scored there is blow by and the result is the glass filled vapor the causes permanent lung damage the same as fiberglass. Any doubts hold a piece of paper to an exhaust pipe and see the result vapor. There is also the storage and the handling of the chemical that the we all know in the present times the dealerships can not afford the equipment. This charade was poorly thought out all the way around. Unfortunately will will not see the health results until years down the road when the afflicted discover to late they have been shafted.
