3854 Boric acid (H3BO3) Boric acid (H3BO3) belongs to the miscellaneous metallic oxoanionic compounds, a subclass of miscellaneous mixed metal/non-metals within the inorganic compounds. This exogenous compound has the chemical formula BH3O3 and an average molecular weight of 61.83 g/mol. At room temperature, it exists as a solid. The compound serves various industrial roles, including use as a pH regulating agent, biocide, stabilizing agent, flame retardant, binder, lubricating agent, stabilizer (PMC11396345), and catalyst (PMC10426397). It is also used as an astringent. Boric acid is found in or released from 55 recorded sources, including electrical and electronic equipment such as antennas, coils, and communication cables; household cleaning and consumer products like bleaching agents and perfumes within detergents and soaps; building and construction materials including ceilings, floors, and roofs; healthcare, pharmaceuticals, and veterinary products such as antiinfectives; and household items like coins. It is also associated with food, food processing, and cookware, including food contact materials, food preservation, and fermentation processes for beer. Recorded exposure routes include cutaneous, infiltration, inhalation, nasal, ophthalmic, oral, rectal, topical, touch, and vaginal, with inhalation supported by literature (PMC12735847). Boric acid has four recorded protein targets: C-C motif chemokine 2 (CCL2), ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase 1 (CD38), epidermal growth factor receptor (EGFR), and interleukin-8 (CXCL8). Regarding health effects, it has a therapeutic effect on colon cancer (PMC10351539). 10043-35-3 7628 BH3O3 61.84 White powder. 171°C 50 mg/mL at 25°C No indication of carcinogenicity to humans (not listed by IARC).
