Description

1-Undecanol (CAS 112-42-5 ), also known by its FEMA 3097 designation, is a medium-chain fatty alcohol used across flavor, fragrance, and surfactant applications. It contributes waxy, citrus-like aromatic character to flavor systems and functions as a surface-active agent and emulsifier in industrial formulations. In food and beverage flavoring, it is used at trace levels. The compound imparts fresh, fatty-citrus top notes in citrus, dairy, and fruit flavor compositions. Personal care formulators incorporate it as an emollient and emulsifier component in creams and lotions. Its specific chain length supports texture and spreadability in conditioning products. In printing and packaging, it acts as a wetting and dispersing agent to improve ink adhesion and substrate compatibility. It also serves as a chemical intermediate in the synthesis of surfactants, esters, and specialty surface-active compounds. These are essential for industrial cleaning and coating systems. The product is supplied as a colorless to pale yellow liquid or low-melting solid depending on ambient temperature. Food-grade material conforming to FEMA specifications is available for flavor applications. Technical-grade material is supplied for industrial and surfactant manufacturing use. Standard packaging includes drums and intermediate bulk containers (IBCs) to ensure safe transport and storage. Contact us for supply of 1-Undecanol Request Quote
