Undecanoic acid

CAS: 112-37-8

Overview

Undecanoic acid (CAS 112-37-8 ), also known as undecylic acid, is a saturated medium-chain fatty acid used across food, cosmetic, and industrial formulations. With FEMA number 3245 , it functions as a flavoring agent and emulsifier.

In food and flavor manufacturing, it contributes fatty, creamy, and waxy notes to dairy, fruit, and savory flavor compositions. Personal care formulators incorporate it into skin conditioning bases and emollient systems.

These applications require controlled spreading and film formation. In lubricant and metalworking fluid formulations, it acts as a boundary lubrication additive and corrosion-inhibiting component for metal surfaces.

Coatings and adhesive manufacturers use it as a surface modifier to improve substrate wetting and adhesion in polymer-based systems. This versatility makes it a staple in modern chemical processing and manufacturing.

Undecanoic acid is supplied as a white to off-white crystalline solid or flake. Food-grade material is available meeting FCC specifications, supporting its use in flavoring and food-contact applications.

Technical-grade product is also offered for industrial end uses in lubricants, coatings, and polymer processing. Our supply chain ensures consistent quality and purity for all your formulation requirements.
