1,2-pentanediol

1,2-Pentanediol (CAS 5343-92-0 ), commercially recognized as pentylene glycol, is a short-chain diol used across personal care and industrial formulations. It functions as a humectant, solvent, and antimicrobial booster. This versatile chemical often replaces more regulated glycols in preservation systems. In personal care, it is used in leave-on and rinse-off formulations such as serums, moisturizers, and cleansers. The ingredient enhances skin feel while supporting preservation efficacy at low concentrations. Coating and resin formulators use it as a reactive diol in polyurethane and alkyd systems. Its hydroxyl groups participate in cross-linking to influence flexibility and cure profile. In adhesive and sealant formulations, it acts as a reactive diluent or chain extender for the system. This helps to control viscosity and final mechanical properties during production. It also performs as a solvent and carrier for active ingredients in cosmetic concentrates and industrial intermediates. 1,2-Pentanediol is supplied as a clear liquid in drum and IBC quantities. Cosmetic-grade material is the most commonly available specification for high-end manufacturing needs. Purity levels are typically at 99% or above to meet personal care formulation standards. Technical-grade supply is also available for industrial coating and polymer applications. Contact us for supply of 1,2-pentanediol Request Quote
