[needs update], Review of the boron toxicity (as boric acid and borates) published 2012 in Journal of Toxicology and Environmental Health concluded: "It clearly appears that human B [boron] exposures, even in the highest exposed cohorts, are too low to reach the blood (and target tissue) concentrations that would be required to exert adverse effects on reproductive functions. A wide variety of sodium tetraborate pentahydrate options are available to … The lethal dose is not necessarily the same for humans. Borax is not a soap or detergent, but rather a salt of boron.Borax is a non-synthetic chemical and is mined directly from the deserts of California and Turkey as a mineral salt.
