Disclosed is a noble &bgr;-hydroxyamide of general formula wherein R
1
is alkyl, alkoxyalkyl or hydroxyalkoxyalkyl derived from at least one hydroxyfunctional compound, R
2
is alkyl, aryl, alkylaryl or arylalkyl derived from at least one carboxyfunctional compound or at least one anhydride, halide or ester of at least one carboxyfunctional compound, R
3
is N-alkyl or N-cycloalkyl derived from at least one alkanolamine and wherein m and n are independent integers and at least 1. In a further aspect the present refers to a process for synthesis of said &bgr;-hydroxyamide. The process comprises the Steps of (i) subjecting a di, tri or polyalcohol to alcoholysis with at least one di, tri or polyalkyl ester of a di, tri or polyfunctional carboxylic acid and (ii) subjecting obtained reaction product to aminolysis with at least one alkanolamine.
