Title (EN) PROCESS FOR PREPARATION OF GRANULAR DETERGENT COMPOSITION OR COMPONENT COMPRISING A WATER-SOLUBLE CATIONIC SURFACTANT
(FR) PROCEDE POUR LA PREPARATION D'UNE COMPOSITION OU D'UN CONSTITUANT DE DETERGENT GRANULAIRE COMPRENANT UN TENSIOACTIF CATIONIQUE HYDROSOLUBLE
Abstract:
(EN) The invention provides a process which comprises the step of drying an aqueous solution or dispersion, the aqueous solution or dispersion comprising a water-soluble cationic surfactant, in the presence of a drying gas wherein the maximum temperature of the drying gas is less than 250 °C. Preferably the drying step is carried out in a co-current spray dryer and the drying gas is air.
(FR) Cette invention se rapporte à un procédé consistant à sécher une dispersion ou une solution aqueuse, laquelle renferme un tensioactif cationique hydrosoluble, en présence d'un gaz desséchant, dont la température maximum est inférieure à 250 °C. L'étape de séchage est de préférence réalisée dans un sécheur à pulvérisation à cocourant et le gaz desséchant est de préférence l'air.
