Product Details

1,3-Butanediol is an organic chemical which belongs to the family of secondary alcohols. At present, 1,3-butanediol is used mainly in surfactants, inks, solvents for natural and synthetic flavoring agents and serves as a co-monomer in manufacturing certain polyurethane and polyester resins. It can also serve as a humectant to prevent loss of moisture in cosmetics, particularly in hair sprays and setting lotions. Besides, 1,3-Butanediol is pharmaceutically involved in the production of colchicine derivatives as a anticancer agent and in the synthesis of dual peroxisome proliferator-activated gamma and delta agonists acting as a hypoglycaemic agent, which is effective for the treatment of diabetes.

Product Usage

Its most extensive use is as an intermediate in the manufacture of polyester plasticisers and other chemical products. It finds some use as a solvent and humectant, a useful chemical intermediate. It has extensive application in the manufacture of structural materials for boats, custom mouldings, and sheets and boards for construction applications. 1,3-Butanediol imparts resistance to weathering plus flexibility and impact resistance. It is also used in the manufacture of saturated polyesters for polyurethane coatings, where the glycol imparts greater flexibility to the polyester molecule. 1,3-Butanediol is currently used in many personal care products.
