A chemical product used medically as a topical antiseptic (bacteria and fungi). It is also used as a disinfectant, insecticide and has other industrial uses. Given its toxic nature, its use as a food preservative has been abandoned. It is still used in the treatment of vaginal candidiasis when resistant to other treatment (Iavazzo 2011).
Since the last update we have not found published data on its excretion in breastmilk.
Absorption through intact skin is negligible (0.23%) (U.S. 2010, Wester 1998). Vaginal absorption is 6% (Prutting 1998).
Virtually everything absorbed via inhalation is eliminated in 24 hours and 96 hours if the absorption was through the digestive tract.
These periods of 24 and 96 hours can respectively be prudent periods of suspending breastfeeding in case the breastfeeding mother has been seriously intoxicated by inhalation or oral administration.
We do not have alternatives for Boric Acid.
