Description
Undecylenic acid (C11) or also called 10-undecenoic acid is an organic unsaturated fatty acid derived from castor oil by cracking. Undecylenic acid is an FDA approved active ingredient in medications for skin infections, and relieves itching, burning, and irritation. In technical applications it is used because if its antifungal properties.appearance (25°C) White or very pale yellow crystalline

Uses
10-Undecenoic Acid, is used for the manufacture of pharmaceuticals, cosmetics and perfumery, including antidandruff shampoos, antimicrobial powders and as a musk in perfumes and aromas. Undecylenic acid can be used in silicon-based biosensors. Monolayers can be made on bare silicon transducer surfaces with the help of covalent bonds between silicon atom and the double bonds of undecylenic acid. The carboxylic acid groups remain available for the conjugation of biomolecules such as DNA or proteins. silicon-based biosensors
natural fungicide
chemical intermediate in fragrance and flavours
cosmetics & personal care: highly effective natural antimicrobial and preservative properties
undecylenic acids-based diols and polyols
additive in cutting fluids (fungicide or as triethanolamine salt as rust inhibiting additive) used as antifoaming and surface active agent. As its sulfo – succinate derivative it is used in anti-dandruff shampoos

Indications
Undecylenic acid, like zinc undecylenate, is very effective as an external drug for treating
moderate dermatophyte infections and yeast dermatitis, but it is not effective for shingles and
for candida infections. Synonyms of this drug are benzevrine, micocid, undetin, and others.

Clinical Use
10-Undecenoic acid (Desenex, Cruex) obtained fromthe destructive distillation of castor oil. Undecylenic acidis a viscous yellow liquid. It is almost completely insolublein water but is soluble in alcohol and most organicsolvents.Undecylenic acid is one of the better fatty acids for useas a fungicide, although cure rates are low. It can be used inconcentrations up to 10% in solutions, ointments, powders,and emulsions for topical administration. The preparationshould never be applied to mucous membranes because it isa severe irritant. Undecylenic acid has been one of theagents traditionally used for athlete’s foot (tinea pedis).Cure rates are low, however.
