Ximenynic acid
Ximenynic acid is trans-11-octadecen-9-ynoic acid,[1] a long-chain acetylenic fatty acid.[1]
It was discovered in the fruit kernels of 3 South American ximenia species (and so named).[2] and found to have the formula C18H30O2.[2]
It can be extracted from the fruit kernels of the Santalum obtusifolium (Sandalwood)[3] and the Australian sandalwood Santalum spicatum[1]
It is also found in seed oil of other plants in the Santalaceae family, including the native cherry Exocarpos cupressiformis and sweet quandong Santalum acuminatum.[4]

Patents
It was the subject of a 2003 European patent (for use in food).[5] The patent application was deemed withdrawn in August 2012.[6]
Uses
It is used in some skincare products.[7]
