Title: (EN) METHOD FOR PREPARING PERSONAL CARE COMPOSITION COMPRISING SURFACTANT AND HIGH MELTING POINT FATTY COMPOUND
(ES) METODO PARA PREPARAR UNA COMPOSICION PARA EL CUIDADO PERSONAL QUE COMPRENDE UN SURFACTANTE Y UN COMPUESTO GRASO DE ALTO PUNTO DE FUSION
Abstract:
(EN) Disclosed is a method of preparing a personal care composition, comprising the steps:(1) preparing a hot oil phase comprising the surfactant and the high melting point fatty compound;(2) preparing a cold aqueous phase comprising the aqueous carrier;and (3) mixing the oil phase and the aqueous phase to form an emulsion;wherein the mixing step (3) comprises the following detailed steps:(3-1) feeding either of the oil phase or the aqueous phase into a high shear field having an energy density of 1.0x102 J/m3 or more;(3-2) feeding the other phase directly to the field;and (3-3) forming an emulsion. The method further requires that:the mixing step (3) is conducted by using a homogenizer having a rotating member;the surfactant is mono-alkyl cationic surfactant and the composition is substantially free of di-alkyl cationic surfactants;and the oil phase contains from 0 to 50%of an aqueous carrier by weight of the oil phase.
(ES) Se describe un método para preparar una composición para el cuidado personal, el método comprende las etapas de:(1) preparar a fase oleosa que comprende el surtactante y el compuesto graso de alto punto de fusión;(2) preparar una fase acuosa fría que comprende el portador acuoso;y (3) mezclar la fase oleosa y la fase acuosa para formar una emulsión;en donde la etapa de mezclado (3) comprende las siguientes etapas detalladas:(3-1) alimentar la fase oleosa o la fase acuosa en un campo de alto cizallamiento que tiene una densidad de energía de 1.0x102 J/m3 o mayor;(3-2) alimentar la otra fase directamente al campo;y (3-3) formar una emulsión. El método requiere, además, que:la etapa de mezclado (3) se lleve a cabo con un homogeneizador que tiene un miembro rotativo;el surfactante sea un surfactante catiónico alquilo de mono cadena y la composición estéprácticamente libre de surtactantes catiónicos de alquilo de doble cadena larga;y que la fase oleosa contenga de 0 a aproximadamente 50%de la portador acuoso en peso de la fase oleosa.
