Overview
Undecylenic Acid also called as 10-Undecenoic acid is an unsaturated fatty acid having its double bond in the 10-position.
It is obtained by cracking of Ricinoleic acid, which is derived from Castor oil. The cracking also yields Heptanal.
Undecylenic acid is known for its anti-fungal properties which means that it prevents the growth of fungus.
It is also the starting material for other important fragrance chemicals and flavouring agents.
Uses of Undecylenic Acid
- Undecylenic Acid is used in the manufacture of Nylon-11 which is an important engineering polymer. Nylon-11 is used for making pipes because of its high strength, flexibility and stability in extreme conditions, electrical wire sheathing, textiles, etc.
- The zinc salt of Undecylenic acid called Zinc Undecylenate is used in various creams and powders to treat fungal infections.
- Undecylenic Acid derivatives are used in the flavours and fragrances industry. The various derivatives and its end use are mentioned below:
| Sr No. | Undecylenic Acid Derivatives | End Use |
| 1 | 10-Undecenoic acid | Woody; sweet |
| 2 | Methyl undecylenate | Banana; honey; oily; citrus; rose;
Earthy; soapy; wine-like |
| 3 | Undecylenic aldehyde or Aldehyde C11 | fatty; citrus; waxy; rose; sweet |
| 4 | Undecyl alcohol or Alcohol C11 | grape; lemon; lime; green; sweet |
| 5 | Ethyl undecanoate | coconut |
- Undecylenic Acid is also used as a platform chemical for manufacturing macrocylic musk such as exaltolide, ethylene brassylate exaltone, cevolide and musk RI.
