Title (EN) METHOD FOR PREPARING AN EMULSION
(FR) PROCÉDÉ DE FORMATION D'UNE ÉMULSION
Abstract:
(EN) The present invention relates to a method for preparing dermo-cosmetic compositions in the form of emulsions, which as emulsifier contain cationized cellulose fibres with a degree of cationic substitution greater than 0.15, the concentration of the microfibres being greater than 0.8% by dry weight in relation to the total weight of the composition. The invention further relates to the use of said cationized cellulose fibres as emulsifying agent, and to the emulsions prepared using said method.
(FR) La présente demande concerne un procédé de préparation de compositions dermo-cosmétiques sous forme d'émulsions comprenant comme émulsionnant des fibres de cellulose cationisées ayant un degré de substitution cationique supérieur à 0,15, la concentration de ces microfibres étant supérieure à 0,8 % en poids de matière sèche par rapport au poids total de la composition; l'utilisation de ces fibres de cellulose cationisées comme agent émulsionnant; ainsi que les émulsions préparées par ce procédé.
