Re: Newbie here, and have a question

Borax is poorly absorbed through the skin;


"Potential health effects
Routes of exposure: Inhalation is the most significant route
of exposure in occupational and other settings. Dermal exposure
is not usually a concern because Borax is poorly absorbed
through intact skin.
Inhalation: Occasional mild irritation effects to nose and throat
may occur from inhalation of Borax dust at levels greater than 10
mg/m3
.
Eye contact: Borax is non-irritating to eyes in normal
industrial use.
Skin contact: Borax does not cause irritation to intact skin.
Ingestion: Products containing Borax are not intended for
ingestion. Borax has a low acute toxicity. Small amounts (e.g., a
teaspoonful) swallowed accidentally are not likely to cause
effects; swallowing amounts larger than that may cause
gastrointestinal symptoms.
Cancer: Borax is not a known carcinogen. "

ps most overdoses of boron are from boric acid, not borax. (boric acid = borax + sulfuric acid) Tweet
