A process for preparing by means of direct oxidation acylglycinates

There is provided a process for the preparation of acylglycinate salts of formula (II) described, wherein R B is a cation mean and / or the corresponding protonated acylglycine acids, characterized in that one or more fatty acid monoethanolamides of the formula (I), wherein R are oxidized with oxygen in the presence of a gebenenenfalls supported bimetallic catalyst comprising gold and a metal of Group VIII of the Periodic Table, in an alkaline medium to one or more acylglycinate salts of formula (II) and in the case of the preparation of the protonated acylglycine acids which, or the Acylglysinatsalze of formula (II) can be further reacted with an acid.
