Borax pentahydrate

CAS: 1303-96-4

Description:
A white, odorless crystalline powder with pronounced hygroscopic properties and excellent solubility in water. When exposed to air for extended periods, the crystals gradually lose their transparency due to surface dehydration. This versatile boron compound exhibits mild alkaline behavior, buffering capacity, and multifunctional reactivity, making it suitable for diverse industrial, agricultural, and consumer applications.

Key Uses:
  • Antimicrobial & Preservation Formulations. Functions as an effective antiseptic and preservative in various products, helping to suppress microbial growth and extend shelf life in cosmetics, adhesives, and industrial materials.
  • Textile Processing & Dyeing. Widely employed as a mordant to pre-treat fabrics, improving dye uptake, color uniformity, and wash-fastness in both natural and synthetic fiber applications.
  • Chemical Manufacturing & Specialty Products. Serves as a foundational raw material for synthesizing boric acid, herbicides, corrosion inhibitors, and advanced cleaning formulations. Also integrated into household and industrial detergents for enhanced performance.
  • Glass, Ceramics & Glaze Production. Integral component in batch mixtures for manufacturing enamels, specialty glass, and ceramic glazes—contributing to improved thermal shock resistance, surface gloss, and chemical durability in finished products.
  • Paper, Pharmaceutical & Cosmetic Industries. Utilized as a functional additive in papermaking for strength enhancement and pH stabilization, and as a buffering or viscosity-modifying agent in medicinal preparations and personal care formulations.
  • Agricultural Applications & Crop Nutrition. Applied as a reliable source of plant-available boron in fertilizers and foliar sprays, supporting critical metabolic functions, flowering, fruit set, and overall crop vitality in boron-deficient soils.
