Boric acid

Boric acid is a weak inorganic acid with the chemical formula BH3O3 and CAS number 10043-35-3. It is a white crystalline powder that occurs naturally in some minerals and volcanic springs. With a molecular weight of 61.84 g/mol, boric acid is widely used in various industrial applications due to its antiseptic, flame-retardant, and buffering properties. It is classified as a reproductive toxin category 1B under CLP regulation.

Boric acid is a white, odorless crystalline powder that is moderately soluble in water. It has a molecular formula of BH3O3 and a molecular weight of 61.84 g/mol. The substance is stable under normal conditions and has a melting point of approximately 171°C. It exhibits weak acidic properties and can form complexes with various organic compounds. Boric acid is non-volatile at room temperature and maintains its stability in dry conditions.

Boric acid serves multiple industrial and commercial purposes including flame retardant applications in textiles and plastics, glass and ceramic manufacturing, wood preservation, and as a buffering agent in chemical processes. It is also used in metallurgy for flux applications, in the production of borosilicate glass, and as an antiseptic in various formulations. Additionally, it finds applications in agriculture as a micronutrient and in water treatment processes.

Boric acid requires careful handling due to its reproductive toxicity classification (Repr. 1B). Essential safety measures include wearing appropriate personal protective equipment such as gloves, safety glasses, and respiratory protection when handling powder forms. Work in well-ventilated areas to minimize inhalation exposure. Avoid skin and eye contact, and never ingest the substance. Pregnant women should avoid handling this material due to its reproductive hazard classification under GHS08 pictogram.

Boric acid should be stored in a cool, dry, well-ventilated area away from incompatible materials. Keep containers tightly closed and protected from moisture to prevent caking. Store away from strong bases and reactive metals. Ensure storage areas are equipped with appropriate spill containment measures. Maintain storage temperatures below 25°C when possible and avoid areas with high humidity. Segregate from food, feed, and drinking water to prevent accidental contamination.

In case of skin contact with boric acid, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with plenty of clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical advice if respiratory irritation occurs. In case of ingestion, do not induce vomiting and seek immediate medical attention.

Boric acid disposal must comply with local and national waste regulations as it is classified as hazardous waste due to its reproductive toxicity. Contact licensed waste disposal companies for proper treatment and disposal. Do not discharge into drains, waterways, or soil. Small quantities may be neutralized and disposed of according to local environmental regulations. Always consult with waste management authorities and follow the safety data sheet recommendations for disposal procedures.

Boric acid transport requirements depend on quantity and packaging specifications. While not assigned a specific ADR class in our data, it may still require proper labeling due to its hazardous classification. Ensure packages are properly sealed, labeled with appropriate hazard information including GHS08 pictogram, and accompanied by safety data sheets. Use appropriate packaging materials that prevent spillage during transport and comply with local transportation regulations for hazardous materials.

Boric acid is subject to various regulations including CLP classification as reproductive toxin category 1B requiring GHS08 labeling and 'Danger' signal word. It falls under REACH regulation requirements for registration and safety data sheet provisions. The substance requires specific risk management measures due to its reproductive toxicity. Users must comply with occupational exposure limits and implement appropriate risk management measures as outlined in extended safety data sheets.
