Methyl Undecylenate is a linear ester with a terminal double bond, that can be used as a chemical intermediate in the synthesis of aromatic chemicals, of polymers or modified silicones. Methyl undecylenate is produced by fractional distillation of the product obtained by the pyrolysis of methyl ricinoleate at a high temperature. Methyl undecylenate is used as a chemical intermediate in the synthesis of organo-modified silicones for hair care preparations and sun care products. It can also be used as a chemical intermediate for synthesizing derivatives based on ammonium or ethanolamide used in hair-care products.
