METHOD FOR PREPARING PERSONAL CARE COMPOSITION COMPRISING MONOALKYL AMINE DUAL SURFACTANT SYSTEM AND SOLUBLE SALT.

摘要

Disclosed is a method of preparing a personal care composition wherein the composition comprising a dual cationic surfactant system of a mono-alkyl amine salt and di-alkyl cationic surfactant, high melting point fatty compounds and soluble salts, and wherein the method comprising the following steps: preparing oil phase at a higher temperature; preparing an aqueous phase at a lower temperature; and mixing them in a high shear field with a rotating member. By the addition of a soluble salt, the surfactants, together with high melting point fatty compounds, can effectively transform to emulsions.
