Material Safety Data Sheet
Sodium tetraborate decahydrate
LD50/LC50:
CAS# 1303-96-4:
Oral, mouse: LD50 = 2 gm/kg;
Oral, rat: LD50 = 2660 mg/kg;
LD 50, or the Lethal Dose 50, is the dose it takes to kill
half of the animals used, generally rats and mice,
because of the close correlation to human toxicity.
Looks like it takes a lot to kill a rat or a mouse, 2 gm per
Kg body weight, which would be aapx 140 gms for
a person. Not that I am advocating ingestion mind you, just
pointing out that what is on the end or your
finger is many orders of magnitude lower than 140 gms,
probably in the range of 1.4 mg.

Subject: CS>OT boron and borax
Does anyone know of any negatives regarding the use of borax as a
dietary source of boron??? Have read that just one joint of the index
finger coated with borax and popped into the mouth will give enough
boron to suffice for daily needs. Need confirmation as to this
information. tia pj
