With 2-butoxyethanol or BUTYL exposure, it should be called the shrapnel chemical

where it starts up first is irrelevant,

because all by itself it can cause cancers of several kinds  *

I would also suspect that if BUTYL is as harmful as I suspect, and some MSDS info confirms,

Randy Pausch would want his family cautioned to avoid it.

Especially in home cleaning products

And to take special note of when 'the sniffles' or diarrhea start up

to notice what is going on differently RIGHT THEN and when 'flu' symptoms start up
