Chemical: Boric acid (H3BO3), tributyl ester

Boric acid (H3BO3), tributyl ester is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Boric acid (H3BO3), tributyl ester are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)

Status: Active Update: 24-08-2018 https://echa.europa.eu/registration-dossier/-/registered-dossier/23096

Boric acid (H3BO3), tributyl ester: Does not have an individual approval but may be used as a component in a product covered by a group standard. It is not approved for use as a chemical in its own right.

An eye and respiratory tract irritant; Oral LD50 (mouse) =2150 mg/kg; Decomposes in the presence of water to boric acid and n-butanol; [HSDB] Decomposed quickly by water; [CAMEO] Hydrolyzed by water; An irritant; [MSDSonline] See Boric acid. See Triethyl borate.

Borates behave similarly to esters in that they react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters/borates with alkali metals and hydrides. Reacts vigorously with oxidizing materials. (NTP, 1992).

2 - Materials that, under emergency conditions, can cause temporary incapacitation or residual injury.

2 - Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Materials would not under normal conditions form hazardous atmospheres with air, but under high ambient temperatures or under moderate heating could release vapor in sufficient quantities to produce hazardous atmospheres with air.

1 - Materials that in themselves are normally stable but that can become unstable at elevated temperatures and pressures.

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

TERRESTRIAL FATE: Tributyl borate is rapidly hydrolyzed to boric acid and n-butanol in the presence of water(1,2). Hydrolysis would be expected to be the dominate fate process for tributyl borate in the environment(SRC).

AQUATIC FATE: Tributyl borate is rapidly hydrolyzed to boric acid and n-butanol in the presence of water(1,2). Hydrolysis would be expected to be the dominate fate process for tributyl borate in the environment(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), tributyl borate, which has a vapor pressure of 0.526 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Tributyl borate is rapidly hydrolyzed to boric acid and n-butanol in the presence of water(3,4). Hydrolysis would be expected to be the dominate fate process for tributyl borate in the environment(SRC).

Occupational exposure to tributyl borate may occur through inhalation and dermal contact with this compound at workplaces where tributyl borate is produced or used. Exposure to the general population may occur via dermal contact with flame retardant textiles treated with tribultyl borate; however, this exposure could be compromised due to the rapid decomposition of tributyl borate upon contact with water. (SRC)

Tributyl borate's production and use in welding flux, as a flame retardant for textiles, and its use in the preparation of borohydrides may result in its release to the environment through various waste streams. If released to air, a vapor pressure of 0.526 mm Hg at 25 °C indicates tributyl borate will exist solely as a vapor in the ambient atmosphere. Tributyl borate is rapidly hydrolyzed to boric acid and n-butanol in the presence of water. Hydrolysis would be expected to be the dominate fate for tributyl borate in the environment. Tributyl borate is expected to have a very short existence in the environment. Occupational exposure to tributyl borate may occur through inhalation and dermal contact with this compound at workplaces where tributyl borate is produced or used. Exposure to the general population may occur via dermal contact with flame retardant textiles treated with tribultyl borate; however, this exposure could be compromised due to the rapid decomposition of tributyl borate upon contact with water.

Maintain an open airway and assist ventilation if nescessary. treat coma, seizures, hypotension, and renal failure if they occur. There is no specific antidote. Administer activated charcoal (although boric acid is not well absorbed). Consider gastric lavage for large ingestions. /Boric acid, Borates, and Boron/

Hemodialysis is effective and is indicated after massive ingestions and for supportive care of renal failure. Peritoneal dialysishas not proved effective in enhancing elimination in infants. /Boric acid, Borates, and Boron/

In acute poisonings, if a large amount has been ingested and the patient is seen within one hour of exposure, gastrointestinal decontamination should be considered ... .It is important to keep in mind that vomiting and diarrhea are common, and severe poisoning may be associated with seizures. Therefore induction of emesis by syrup of ipecac is probably contraindicated in these exposures. Catharsis is not indicated if diarrhea is present. /Boric acid and Borates/

If ingestion of borate has been massive (several grams), or has extended over several days, administer intravenous glucose and electrolyte solutions to sustain urinary excretion of borate. Monitor fluid balance and serum electrolytes (including bicarbonate capacity ) regularly. Monitor cardiac status by ECG. Test the urine for proteins and cells to detect renal injury, and monitor serum concentration of borate. Metabolic acidosis may be treated with sodium bicarbonate. If shock develops, it may be necessary to infuse plasma or whole blood. Administer oxygen continuously. If oliguria (less than 25 to 30 mL urine per hour) occurs, intravenous fluids must be slowed or stopped to avoid overloading the circulation. Such patients should be referred to a center capable of providing intensive care for critically ill patients. /Boric acid and Borates/
