Description and Uses

(^+)-1,3-Butanediol acts as a co-monomer in the production of polyurethane and polyester resins. It is used as a humectant (to prevent loss of moisture) in cosmetics, especially in hair sprays and setting lotions. It is used in surfactants, inks, solvents for natural and synthetic flavorings. It is involved in the synthesis of dual peroxisome proliferator-activated gamma and delta agonists acting as euglycemic agents, which is used in the treatment of diabetes.
