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
  • Anti-odor properties
Common applications include:

Cosmetic Applications

Oleris® Methyl undecylenate is used as a chemical intermediate in the synthesis of:

  • Cosmetics with surfactant or anti-dandruff properties
  • Organo-modified silicones for hair care preparations and sun care products
  • Derivatives based on ammonium or ethanolamide used in hair care products

And in particular is used as such in formulations requiring its anti-odor properties.

INCI name: methyl undecylenate or methyl undecenoate.

Flavors and Fragrances Applications

Oleris® Methyl undecylenate is used in the synthesis of important aromatic compounds having a large number of carbon atoms like macrocyclic musks. Oleris® Methyl undecylenate is used as such in formulations requiring its anti-odor properties.

Polymerization and metathesis.

Oleris® Methyl undecylenate is used in polymerization as a chain regulator and in metathesis due to its terminal double bond and its high reactivity.
