Process Optimization and Application of Camel Oil Microcapsules in Facial Cream

The optimal process conditions of Camel oil microcapsules were investigated using the encapsulation rate as the evaluation index, through single-factor and orthogonal experiments. The physicochemical properties, storage stability and photosensitivity indexes of Camel oil microcapsules were also evaluated. The results showed that: (1) the optimal preparation conditions for Camel oil microcapsules were as follows: wall to core volume ratio of 3∶4, emulsifier volume ratio of 1∶2, total wall material volume fraction of 2%, and homogenization speed of 30 000 rpm, and the encapsulation rate of the prepared microcapsules was 92.67%; (2) Camel oil was successfully encapsulated in the composite wall material, with no chemical changes occurring during the encapsulation process; The microcapsules of Camel oil were spherical and uniform in shape. The microcapsule of Camel oil demonstrated good thermal stability when it is below 220 ℃. The oxidation stability of Camel oil microcapsules was much better than that of unencapsulated Camel oil, significantly prolonging the storage time. (3) The pH value of Camel microcapsule face cream was 7.6, and the sensory evaluation scored 21.6 points, with no delamination or demulsification, showing good stability.
