Title (EN) METHOD FOR THE PREPARATION OF CATIONIC SURFACTANTS
(FR) PROCÉDÉ DE PRÉPARATION DE TENSIOACTIFS CATIONIQUES
Abstract: front page image
(EN)The invention relates to a method of the preparation of a cationic surfactant, derived from the condensation of fatty acids and esterified dibasic amino acids, having the formula (I): having a mean particle diameter of less than 300 μm; by preparing the cationic surfactant with a remaining content of water less than 5% by weight in a first step; and milling this dried material in the second step.
(FR)Cette invention concerne un procédé de préparation d'un tensioactif cationique, dérivé de la condensation d'acides gras et d'acides aminés dibasiques estérifiés, de formule (I) : ayant un diamètre de particule moyen inférieur à 300 µm. Le procédé comprend la préparation du tensioactif cationique à une teneur résiduaire d'eau inférieure à 5 % en poids dans une première étape; et le broyage de ce matériau séché dans la seconde étape.
