Title (EN) N-ACYL ETHYLENEDIAMINETRIACETIC ACID SURFACTANTS AS ENZYME COMPATIBLE SURFACTANTS, STABILIZERS AND ACTIVATORS
(FR) TENSIOACTIFS D'ACIDE N-ACYL ETHYLENEDIAMINETRIACETIQUE EN TANT QUE TENSIOACTIFS, STABILISATEURS ET ACTIVATEURS COMPATIBLES AVEC DES ENZYMES
Abstract: front page image
(EN)Compositions including one or more enzymes and as the compatible chelating surfactant, salts of N-acyl ethylenediaminetriacetic acid ('ED3A'). Salts of N-acyl ED3A do not readily denature various enzymes, and thus are highly compatible with such enzymes, and enhance their detergent effectiveness to an unexpected degree.
(FR)La présente invention a pour objet des compositions comprenant une ou plusieurs enzymes et, comme tensioactifs chélatants, des sels d'acide N-acyl éthylènediaminetriacétique ('ED3A'). Les sels de N-acyl ED3A ne dénaturent pas facilement les diverses enzymes, avec lesquelles ils sont donc très compatibles, et dont ils augmentent de façon étonnante la capacité nettoyante.
