What is boric acid?

Boric acid, also known as hydrogen borate or orthoboric acid, is a white crystalline boron compound used in many industrial and specialty applications. Unlike acetone, methanol, or ethanol, boric acid is typically sourced as a solid, so particle size, purity, packaging, and moisture protection can matter in procurement.

Industrial buyers use boric acid in glass, ceramics, flame-retardant systems, adhesives, pharma, cosmetics, agriculture, metallurgy, and laboratory applications. Each use case can require different purity, mesh size, impurity limits, and documentation.

Chemical Dekho indexes boric acid by CAS 10043-35-3, making it easier for buyers to separate boric acid from borax, boron oxide, borates, and other boron-containing materials during supplier comparison.

Applications

Where boric acid is used

Boric acid sits at the intersection of boron chemistry and practical manufacturing, so its buying specification can vary widely by application.

Glass, ceramics and enamels

Used as a boron source in glass, ceramic, glaze, enamel, and heat-resistant material workflows.

Pharmaceutical and personal care

Used in selected pharma, laboratory, cosmetic, and personal-care applications where grade and impurity profile are important.

Flame retardants and materials

Used in selected flame-retardant systems, insulation materials, adhesives, and polymer-related applications.

Agriculture and micronutrients

Used in boron nutrition and agro-related products where application rate, purity, and regulatory fit must be checked.

Grade Selection

How to choose the right boric acid grade

Boric acid buying should start with application and physical form. Buyers may need powder, granular, crystalline, technical, pharma, laboratory, or agriculture-oriented grades. Particle size, assay, moisture, insoluble matter, and impurity limits can affect performance.

Because boric acid is a solid, packaging and storage are part of the specification. Ask whether bags are moisture-protected, whether pallets are available, and whether the supplier can provide COA, SDS, and grade-specific documentation.

RFQ checklist

  • Grade and application
  • Assay percentage
  • Particle size or mesh
  • Moisture and insolubles
  • Bag size and palletization
  • COA/SDS

Specification Snapshot

Boric Acid specifications buyers usually compare

CAS number: 10043-35-3
Formula: H3BO3
Molecular weight: 61.83 g/mol
Appearance: white crystalline powder or granules
Common names: hydrogen borate, orthoboric acid
Key buying docs: COA, SDS/MSDS and TDS

For boric acid, physical specification matters as much as chemical identity. Particle size, moisture protection, and impurity limits can decide whether a low-priced offer is actually suitable.

Safety basics: handle boric acid with dust and exposure controls.

This blog is a buyer guide, not a replacement for your SDS, site EHS procedure, or local compliance requirements.

Boric acid should be handled according to SDS guidance with dust control, suitable PPE, good housekeeping, and proper storage. Buyers should confirm regulatory suitability for their specific application and region.

Control dust during handling
Use suitable PPE
Protect bags from moisture
Check application regulations
