Arkema is a Founding Member of Pragati:
The World's First Sustainable Castor Program

The goal of the Pragati project is to enable sustainable castor crop production.



Used as a 100% bio-based, sustainable, carbon-neutral building block where the following properties might be needed:
  • High purity 
  • 100% Linearity
  • High reactivity
Common applications include:

Cosmetic Applications

Oleris® Undecylenic acid is a natural fatty acid and a physiological chemical contained in human sweat, tears, and hair. It is used as a chemical intermediate in the synthesis of:

  • Cosmetics requiring its cleansing, emulsifying, preservative, or surfactant properties like esters, ethanolamide derivatives and salts (calcium and zinc) with bacteriostatic properties
  • For sustainable vegetable-based & natural ingredients

INCI name: undecylenic acid 

Synthetic Lubricant Applications

Oleris® Undecylenic acid can be used as a building block for synthetic lubricants, to improve their renewable composition and increase their viscosity index. 


Oleris® Undecylenic acid is used to functionalize polymers and as a chain regulator, due to its double bond and high reactivity. 

Flavors and Fragrances Applications

Due to its bifunctionality, Oleris® Undecylenic acid is used as an intermediate in the synthesis of aromatic chemicals like:
