Title
(EN) METHOD FOR PREPARING PERSONAL CARE COMPOSITION COMPRISING SURFACTANT AND HIGH MELTING POINT FATTY COMPOUND
(FR) PROCÉDÉ DE PRÉPARATION D'UNE COMPOSITION DE SOINS PERSONNELS RENFERMANT UN TENSIO-ACTIF ET UN COMPOSÉ GRAS À POINT DE FUSION ÉLEVÉ
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.
(FR)
L'invention porte sur un procédé de préparation d'une composition de soins personnels, comprenant les étapes de : (1) préparation d'une phase huileuse chaude renfermant le tensio-actif et le composé gras à point de fusion élevé; (2) préparation d'une phase aqueuse froide renfermant le support aqueux; et (3) mélange de la phase huileuse et de la phase aqueuse pour former une émulsion. L'étape de mélange (3) comprenant en détail les étapes suivantes : (3-1) introduction, soit de la phase huileuse, soit de la phase aqueuse dans un champ à cisaillement élevé présentant une densité d'énergie de 1,0 x 102 J/m3 ou plus; (3-2) introduction de l'autre phase directement dans le champ; et (3-3) formation d'une émulsion. Le procédé exige en outre que l'étape de mélange (3) soit conduite à l'aide d'un homogénéisateur comportant un élément tournant; que le tensio-actif soit un tensio-actif cationique monoalkylé et que la composition soit sensiblement exempte de tensio-actifs cationiques dialkylés; et que la phase huileuse contienne de 0 à 50 % en poids d'un support aqueux par rapport au poids de la phase huileuse.
