What's Too Much?
... of 2-butoxyethanol?
Has OSHA decided to reduce what is considered safe in recommended exposure?
... although already low?
What does it do anyway?
As a fertilizer for microbes, assuming the right ones are present:
surfactant and stabilizer as stated on the Inipol EAP 22 MSDS...
"Its primary purpose in the formula is to keep the whole mess pourable,
although if they heat it first, I have no answer for that at all."
"You don't need large amounts of surfactants for the bugs either, just enough to help solubilize the oil so its edible.
2-butoxyethanol is not a food source for ALL bugs, just some. Of course neither is petroleum a food source for them all."
"Too much surfactant is harmful to fish too, so the amount must be strictly controlled and limited."
"A researcher * was also amazed bacteria had not broken down the oil." *.
