ABSTRACT: It was tried to microencapsulate camellia oil using heterocoagulation
between fatty acid dissolved in camellia oil and chitosan dissolved in the
continuous water phase. Oleic acid as a fatty acid was dissolved in camellia oil in order to
certainly form the microcapsule shell made from oleic acid and chitosan. The
microcapsules were observed with optical microscope and characterized about the
diameters, ζ-potential, FTIR analysis
and adhesion feature on human hair. Microcapsules with the mean diameter in the
range from ca. 1.5 μm to 4.5 μm could be prepared with the preparation method
presented in this study. The oil droplets of camellia oil charged negatively to be -54.6 mV and
the microcapsules charged positively to be 59.6 mV. The
microcapsules adhered well on the negatively charged human hair and were kept
stably before and after drying at room temperature for 24 h and blowing.
