Product Application
Diols deliver high water solubility, good hygroscopicity and strong reactivity with numerous organic compounds, typically along linear aliphatic carbon chains. As a linear diol with two hydroxyl groups, 1,2-Octanediol shows notable bacteriostatic and bactericidal effects, making it a reliable preservative in cosmetic formulations. It also works effectively in coating materials, slurries, paper manufacturing and water circulation systems to protect against bacteria and fungi. In personal care and cosmetic products, it functions as an emollient, humectant and wetting agent.
