Product Details
1,3-Butanediol is an organic secondary alcohol with versatile applications. It is widely used as a key ingredient in surfactants, inks, and as a solvent for natural and synthetic flavorings. Additionally, it acts as a co-monomer in the production of select polyurethane and polyester resins. In personal care and cosmetics, it is valued as a humectant that helps lock in moisture, particularly in hair sprays and setting lotions. Moreover, it plays a significant role in pharmaceutical manufacturing, being involved in the synthesis of colchicine-based anticancer compounds and the development of dual peroxisome proliferator-activated receptor gamma/delta agonists, which serve as effective hypoglycemic agents for diabetes management.
