Abstract: The application relates to a process for the synthesis of organic sulfonic acid salts of amino acid esters comprising the steps of (i) reacting at least one lactam with at least 3 carbon atoms in the lactam ring with at least one organic sulfonic acid in an aqueous solution, (ii) esterification of the organic sulfonic amino acid salt of step (i) with at least one alcohol with at least 8 carbon atoms comprising at least one hydroxyl group, (iii) optionally removal of water and/or removal of excess alcohol of step (ii). The application also relates to organic sulfonic acid salts of amino acid esters of the general formula (I).

Abstract: The present invention relates to a process for the synthesis of organosulfate salts of amino acid esters comprising the steps of reacting at least one lactam with at least 3 carbon atoms in the lactam ring with sulfuric acid in an aqueous solution followed by esterification of the reaction product of the previous step with at least 200 mol-% of at least one alcohol selected from the group consisting of linear alkyl alcohol containing one hydroxy group, branched alkyl alcohol containing one hydroxy group, linear alkylether alcohol containing one hydroxy group, branched alkylether alcohol containing one hydroxy group, phenoxyalkanols containing one hydroxy group, and mixtures thereof; followed optionally removal of water and/or removal of excess alcohol.

Abstract: The present invention relates to copolymers which are formed from specific amounts of (a) ethylene and (b) monomer(s) selected from propylheptylacrylate and propylheptyl-methacrylate, and optionally at least one further monomer. Said copolymers are useful as oil soluble additives for cosmetic formulations and especially oil depositioning enhancers for rinse-off formulations.
