Process to prepare a cationic nanoemulsion |
摘要 |
Production of cationic nanoemulsions comprises mixing a fatty compound (I) and a nonionic surfactant (II) in the melt, adding water to form an oil-in-water nanoemulsion, and adding a cationic surfactant. Production of cationic nanoemulsions comprises mixing a fatty compound (I) and a nonionic surfactant (II) at a temperature above the m.pt. of (I) and (II) at atmospheric pressure, where the ternary (I)/(II)/water phase diagram has at least one zone in which an oil-in-water nanoemulsion phase exists and the concentrations of (I) and (II) are selected so that this zone can be attained by simple dilution with water; adding water to form a nanoemulsion; and adding a cationic surfactant. An Independent claim is also included for a cosmetic composition in the form of a cationic nanoemulsion produced as above. |
