2-Aminoeicosansdiaic acids of the formula WHEREIN N IS 7 OR 8, AND R1 and R2 are hydrogen or lower alkyl, are readily prepared by Strecker reaction and hydrolysis from the mixture of methyl 9-formylstearate and methyl 10-formylstearate which results from hydroformylation of methyl oleate, and is referred to hereinafter as methyl 9(10)-formylstearate. The aqueous neutral or alkaline solutions of the acids have excellent detergent properties.
