Description
1,2-Pentanediol (CAS 5343-92-0) is a short-chain diol supplied under trade names including Hydrolite 5, A-Leen 5, and Diol PD, and abbreviated as PTD. It carries no E-code designation. It belongs to the alcohols and glycols chemical family with EC number 226-285-3.
In personal care formulations, 1,2-Pentanediol functions as a humectant by binding water within the skin matrix and as a solvent that solubilises fragrance components and active ingredients at low use levels. In coatings and adhesive systems, it acts as a crosslinker by reacting with isocyanate or epoxy groups to build network structure and improve film integrity.
This material is available in standard liquid grade and is compliant with REACH regulations for supply within the EU. It is typically offered in drums and IBC containers. Procurement teams should confirm current SDS documentation and batch-specific CoA for formulation qualification purposes.
