1-nonanol

CAS: 143-08-8

Overview

1-Nonanol (CAS 143-08-8 ), also known as nonyl alcohol, is a medium-chain fatty alcohol used as a fragrance ingredient, flavoring agent, and chemical intermediate across personal care, food, and industrial markets.

Approved under FEMA 2789 , it delivers a characteristic rose-citrus odor profile that supports its use in both flavor and fragrance formulations. In food and beverage, it functions as a flavoring agent.

It contributes floral and fatty notes to products such as citrus drinks, dairy flavors, and baked goods. Personal care formulators incorporate it as an emollient and emulsifier component in skin creams and lotions.

In hair care products, it aids dispersion of active ingredients. In coatings and industrial chemistry, it serves as a solvent modifier and surface wetting agent, improving substrate adhesion and film formation.

It also acts as a chemical intermediate in the synthesis of plasticizers, surfactants, and specialty esters for adhesive and sealant applications. This versatility makes it a staple in chemical manufacturing.

1-Nonanol is supplied as a clear to pale yellow liquid in drum and IBC quantities. Food-grade material meeting FEMA specifications is available for flavor and fragrance applications to ensure safety.

Technical-grade product is standard for industrial and coating end uses. All batches are tested to ensure they meet rigorous quality benchmarks for purity and performance across various industrial sectors.
