Boric Acid 99.5% Industrial Grade CAS 11113-50-1 for Industrial, Agricultural & Cosmetic Use

Boric Acid (CAS:11113-50-1, molecular formula H₃BO₃) is refined by advanced inorganic mineral processing and recrystallization purification technology, finished with minimum 99.5% effective content. The product exists as colorless transparent scaly crystal or white crystalline powder, odorless, mildly soluble in cold water and greatly soluble in hot water, with weak acidity, excellent bacteriostasis, corrosion inhibition, flame retardant and glass forming performance. Our production adopts raw ore impurity removal and multi-stage recrystallization to strictly control sulfate, chloride, heavy metal and water-insoluble impurities, guarantee stable product index and consistent practical performance. Thanks to diversified functional characteristics, this high-purity boric acid is widely applicable in glass manufacturing, ceramic glaze, cosmetic raw materials, agricultural insect repellent, electroplating processing and daily fine chemical industries, satisfying industrial, agricultural and cosmetic-level production requirements simultaneously.

Applications
**Glass & Ceramic Industry (Major Consumption Field)**: Core raw material for borosilicate glass, optical glass and heat-resistant glass production. It lowers glass melting temperature, improves finished glass transparency, heat resistance and mechanical strength, reducing raw material consumption and production energy cost. In ceramic and enamel production, boric acid serves as critical glaze flux agent to optimize glaze fluidity, eliminate glaze pinhole and crack defects, enhance glaze surface smoothness, gloss and adhesion between glaze and ceramic blank.
**Cosmetic & Daily Chemical Manufacturing**: Approved mild functional raw material for shampoo, body wash, skin care lotion and disinfectant cosmetic products. It works as pH regulator, mild antiseptic and anti-itching additive, inhibiting harmful microorganism reproduction inside cosmetic formulas and stabilizing product system pH value; also widely used for production of suppository and external skin care auxiliary raw materials with moderate irritation.
**Agricultural Plant Protection & Crop Cultivation**: Important trace boron fertilizer and mild bactericide for fruit trees, vegetables and field crops. Boron element promotes crop flower bud differentiation, pollen germination and fruit setting rate, effectively prevents crop blossom drop and fruit malformation caused by boron deficiency. Diluted boric acid solution is prepared into low-toxicity foliar spray to restrain partial fungal diseases of fruits and vegetables, realizing nutrient supplement and disease prevention in one application.
**Electroplating & Metal Surface Treatment**: Key pH buffering additive for nickel plating, tin plating and other electroplating bath solutions, stabilizing plating liquid acid-base environment to improve coating uniformity, brightness and compactness, effectively reducing plating pinhole and rough surface problems on metal workpiece. It also acts as auxiliary cleaning agent for metal degreasing and rust removal in precision hardware processing.
**Other Industrial Fields**: Used as flame retardant additive for wood, fabric and paper to improve fireproof performance of finished products; serve as catalyst auxiliary in organic synthesis and raw material for producing various borate chemical derivatives; applied in welding flux production to remove oxide layer on welding metal surface during welding operation.

Product Advantages
