Description

1,3-Pentanediol CAS NO 3174-67-2 is a versatile, high-purity diol valued for its excellent solvency, humectant properties, and favorable safety profile. This compound serves as a key building block and functional ingredient across diverse industrial and consumer-facing sectors. It is particularly sought after by manufacturers in the personal care, pharmaceutical, and specialty chemical industries for formulating high-performance products.

Application

• Personal Care & Cosmetics: Acts as an effective humectant, solvent, and viscosity modifier in skin creams, lotions, serums, and hair care products, providing enhanced moisturization and a smooth sensory feel.
• Pharmaceutical Intermediates: Utilized as a chiral building block in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals, leveraging its specific molecular structure.
• Polymer & Resin Production: Serves as a monomer or co-monomer in the production of polyesters, polyurethanes, and alkyd resins, contributing to flexibility and durability.
• Industrial Solvents & Cleaning Formulations: Employed as a medium-polarity solvent in industrial cleaners, degreasers, and ink formulations due to its good solvating power and relatively low volatility.
• Food & Flavor Industry: Used as a carrier solvent and humectant in flavorings, food additives, and related applications where high purity is essential.
• Antifreeze & Deicing Fluids: Functions as a base fluid or additive in specialty low-toxicity antifreeze and deicing formulations.
