Boric Acid is easy to buy and surprisingly easy to buy wrong. The difference shows up when a batch will not clear, when boron addition does not match the calculation, or when your filtration load suddenly doubles after a supplier change. SGS & Company supplies Boric Acid 99.5% with lot discipline, clarity-focused quality checks, and documentation that supports qualification across pharma, lubricant, and fertiliser routes. Procurement gets a stable grade definition, operations get predictable make-up behaviour, and QA gets traceability that holds up in audits, supported by Chemical Exporters in India.

About Boric Acid

Boric Acid is a weak boron acid supplied as a crystalline powder used as a boron source and mild buffering component across multiple intermediate routes. What matters for procurement is not only the assay, but how the material behaves in your makeup and reaction environment. Buyers typically evaluate assay basis, solution clarity at a defined concentration, insoluble matter, and impurity lines that can affect downstream stability or filtration. COA format, test methods, and grade mapping can be shared during quotation to align with your QA acceptance.

Applications

Chemical Intermediates (Pharma, Lubricants, Fertiliser)

  • ♦
    Boric Acid is used as a controlled boron source where consistent boron contribution and predictable dissolution matter for batch repeatability. In intermediate chemistry, teams focus on clarity and impurity control to protect downstream filtration and stability. In lubricant and fertiliser routes, buyers value a grade that stays consistent in handling, blending, and solution makeup, so process adjustments are not needed with every new lot.

Safety & Handling

  • ♦Avoid breathing dust and use goggles and gloves during charging.
  • ♦Store sealed and dry.
  • ♦Many SDS formats classify boric acid for reproductive toxicity, so follow the supplied SDS and site controls for restricted handling where required.

Frequently Asked Questions

Common Questions About Reaching Us

Most differences come from particle condition and insoluble residue, not from the headline assay. In pharma and lubricant steps, even small insolubles can show up as haze, longer dissolution time, or higher filtration load.
Prepare a solution at your actual working strength and temperature, mix for a fixed time, then check clarity and visible residue after a short settle. This predicts filtration load better than appearance in the bag.
Dissolution is strongly temperature-dependent and slow in cold water. Plants that charge into cold make-up tanks often see undissolved crystals and assume impurity. Warm up the makeup water, and controlled addition order usually fixes it.
Haze is commonly caused by water content and local over concentration zones that create temporary borate-rich microphases. Tight control of addition rate, mixing intensity, and temperature window is usually more effective than raising concentration.
Particle size mismatch with the rest of the blend and moisture pickup during storage are the typical causes. Many sites control this with consistent bag storage, controlled blending sequence, and a particle condition suited to their blending equipment.
Pricing typically changes with particle condition requirements, insoluble control expectations, and the level of impurity reporting needed for your route, along with packing configuration and delivery lane. Share your application and monthly volume to Get a Quote, subject to availability.
Validated routes usually need the same grade definition and a consistent COA format across lots. SGS & Company is a chemical supply distribution company based in India and can align COA, SDS, and traceability for your approval file during quotation. Get a Quote, subject to availability.
