Description

1,3-Butanediol is a versatile, high-purity diol valued for its excellent solvent properties, low toxicity, and high boiling point. This compound is a critical intermediate and functional ingredient across numerous high-value manufacturing sectors. Key industries that rely on this material include pharmaceuticals, cosmetics, food & flavoring, and industrial chemical synthesis. Its stability and compatibility make it a preferred choice for demanding formulations and processes.

Application

• Pharmaceutical Intermediate: Used as a building block in the synthesis of various active pharmaceutical ingredients (APIs) and as a solvent for drug formulations.
• Cosmetics & Personal Care: Functions as an effective humectant and solvent in skin creams, lotions, and hair care products, providing moisture retention and a smooth texture.
• Food & Flavor Industry: Serves as a carrier solvent for flavors, fragrances, and food-grade colorants, and is used in the production of certain food additives.
• Industrial Chemical Synthesis: Acts as a monomer for polyesters and polyurethanes, and as a precursor for plasticizers and other specialty chemicals.
• Electronics: Employed as a high-purity solvent in the production of printed circuit boards and electronic chemicals.
• Antifreeze & Deicing Fluids: Used in formulations for low-toxicity antifreeze and aircraft deicing fluids due to its favorable freezing point depression.
