Method for Preparing Personal Care Composition Comprising Surfactant and High Melting Point Fatty Compound

A method of preparing a personal care composition,

• wherein the composition comprises:
• a cationic surfactant;
• a high melting point fatty compound;
• and an aqueous carrier,
• wherein the method comprises the steps:
• (1) preparing an oil phase comprising the surfactant and the high melting point fatty compound, wherein the temperature of the oil phase is higher than a melting point of the high melting point fatty compound;
• and
• (2) preparing an aqueous phase comprising the aqueous carrier, wherein the temperature of the aqueous phase is below the melting point of the high melting point fatty compounds;
• 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 about 1.0×102 J/m3 or more;
• (3-2) feeding the other phase directly to the field;
• and
• (3-3) forming an emulsion;
• wherein the oil phase contains from 0 to about 50% of the aqueous carrier by weight of the oil phase.
