Abstract: The present invention relates to N acyl and O acyl derivatives of N,N-bis(2,2-dimethyl-3-hydroxypropyl)amine which are produced as follows: ammonium halide, sulphate or aldehyde, and isobutyl aldehyde are subjected to condensation reaction and the obtained product is reduced to the corresponding amino alcohol.
