APPLICATIONS
1,8-Octanediol, linear diol containing two primary hydroxyl groups at terminal locations for reaction of di-substitution, is used as a monomer and intermediate in organic synthesis including polyesters, polyurethane, elstomers, polymer crosslinkers, parmaceuticals. It is also used in gasoline refining and in pharmaceutical manufacturing. Linear diol containing two primary hydroxyl groups, has  bacteriostatic and bacteriacidal properties which are useful in cosmetics as a preservative. It is also used in coating materials, slurries, paper mills and water circulation systems for the effective preservation against bacteria and fungi. It is used as an emollient, humectant, and wetting agent in cosmetic and skin care products. Linear diols are versatile monomers and intermediates in organic synthesis and polymerization.
