  • Applications

    Benzohydrol (benzyl alcohol) is widely used as a solvent and processing aid across multiple industries. In perfumery and cosmetics, it serves as a solvent for fragrance ingredients and as a low odor carrier, and it can function as a preservative or stabilizer in some formulations. In household products and cleaning formulations, it provides solvency to dissolve resins, oils, and surfactants, aiding formulation and product performance. In coatings, inks, and adhesives, it acts as a versatile solvent and reactive intermediate, helping adjust viscosity and cure characteristics. In industrial manufacturing, it is used as an intermediate for synthesizing benzyl derivatives, such as benzaldehyde and benzoate esters, and as a raw material in the production of specialty polymers. In electronics and precision cleaning, benzyl alcohol is commonly employed as a cleaning solvent for circuit boards and delicate components. Its use is subject to local regulations and formulation limits.
