1-hexanol

CAS: 111-27-3

Overview

1-Hexanol (CAS 111-27-3 ), also known as n-hexyl alcohol, is a medium-chain primary alcohol used as a chemical intermediate, solvent, and fragrance ingredient across industrial and consumer product manufacturing.

Its controlled reactivity with isocyanates, acids, and anhydrides makes it a practical building block in polymer and coating chemistries. In coatings and adhesives, it functions as a reactive diluent and chain extender.

This chemical influences crosslink density and film flexibility in polyurethane and alkyd systems. Plasticizer and polymer synthesis rely on it as an esterification feedstock, producing hexyl esters for resins.

These esters modify the softness and processing behavior of PVC and similar materials. Personal care formulators incorporate n-hexyl alcohol as an emollient and emulsifier co-ingredient in skin and hair products.

The compound supports texture and phase stability in cosmetic formulations. Assigned FEMA 2567 , it also serves as a flavoring agent in food-grade applications, contributing a mild floral-green note.

It is used in beverages, confectionery, and fragrance compositions. 1-Hexanol is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for high-volume industrial buyers.

Standard commercial grades include technical and high-purity specifications. Food and flavor applications typically require material meeting FCC or equivalent quality standards for safety and compliance.
