Local:
Undecylenic Acid is an unsaturated carboxylic acid. The molecules of most natural fatty acids have an even number of carbon chains due to the linkage together by ester units. Analogous compounds of odd numbers carbon chain fatty acids are supplemented synthetically. Pelargonic acid, C-9 odd numbers carbon chain fatty acid, is relatively high cost fatty acid. Pelargonic acid can be prepared by ozonolysis which uses ozone is to cleave the alkene bonds. Eexample of ozonolysis in commerce is the production of odd carbon number carboxylic acids such as azelaic acid and pelargonic acid and simple carboxylic acids such as formic acid and oxalic acid. When ricinoleic acid, an unsaturated fatty acid containing one -OH group, derived from castor oil, is pyrolyzed by heating in the absence of air, it breaks down to give undecylenic acid and n-heptaldehyde. This product has the bifunctionality, odd carbon number and the position of its unsaturated solid bond at the end of the chain, makes it a versatile tool for chemical synthesis. It's anti-fungal properties are useful in cosmetics and pharmaceuticals. Undecylenic Acid and its aldehyde are used to formulate perfumes. Undecylenic acid and its zinc salt are used for the treatment and prevention of superficial fungus infections of the skin, primarily tinea pedis as well as relieves itching, burning and irritation.

Undecylenic Aldehyde is one of common ingredient in perfumery. It's end applications include soap, detergent, beauty care product, household product. (Olfactive Note : aldehydic, intense, woody, Herbaceous, floral, sweet, waxy, fresh )
