Isoeugenol

CAS: 97-54-1

Overview

Isoeugenol (CAS 97-54-1 ), also known by its FEMA 2468 designation and commercially as 4-Propenylguaiacol, is a naturally derived phenolic compound sourced from essential oils and produced synthetically for industrial supply.

It functions primarily as a fragrance ingredient and flavoring agent across personal care, food, and industrial applications. In fragrance formulation, it contributes warm, spicy, carnation-like notes to fine perfumes and soaps.

The compound is used in cosmetic products where it also provides antioxidant stabilization to the finished formula. Food manufacturers use it as an approved flavoring to impart clove and spice character in baked goods and confectionery.

In beverages, it provides a distinct aromatic profile. In polymer and plastics processing, its phenolic structure supports UV stabilization and antioxidant protection, extending the service life of polymer compounds exposed to light and heat.

Printing ink formulators incorporate it as a stabilizer to protect resin systems and colorants from oxidative degradation during storage and application. This ensures the longevity and quality of industrial coatings and inks.

The product is supplied as a pale yellow to amber liquid. Standard commercial grades include food-grade material meeting FCC specifications and fragrance-grade product conforming to industry purity requirements.

Technical-grade material is available for polymer and industrial applications where food or cosmetic compliance is not required. This versatile chemical serves a wide range of manufacturing needs across multiple global sectors.
