Summary : Known since antiquity, Castor Oil has been first used in medicine. Now, even if it remains present in small quantities as an excipient in many pharmaceutical specialties, it finds a lot of applications in cosmetics, industrial applications and chemical industry. Castor Oil specificity comes from its high content of ricinoleic acid (up to 85%) that combines a double bond and an hydroxyl function in the heart of a 18 carbons linear chain. This particular structure is the key of an unique chemistry developed by ARKEMA that gives by thermal cracking a wide range of compounds with either 7 or 11 carbon atoms. A whole range of innovative chemistries and end use products are generated from these base reaction products. They are used in every-day life, to improve our comfort and safety but also in very specific applications with very high technical requirements. Synthesized from undecylenic acid, 11-amino-undecanoic acid, 100% based on renewable resources, is the precursor to biobased polymers combining high performance and sustainability: Rilsan ®, Rilsan Fine Powder ®, Pebax Rnew ®.

Keywords : Castor Oil, ricinoleic acid, oenanthol, C7 derivatives, undecylenic acid, C11 derivatives
