| Abstract: | The influence of sucrose laureate and sucrose oleate on the in vivo percutaneous penetration of octyl methoxycinnamate (OMC) formulated in i) colloidal suspensions (nano-emulsions and nanocapsules), and ii) conventional o/w emulsions was evaluated. The results showed that nano-emulsions formulated with sucrose laureate exhibited the highest penetration in the stratum corneum compared to the other formulations. A two-fold increase in OMC skin deposition was observed with the nano-emulsion containing sucrose laureate when compared to the control. The data obtained suggest that the total amount of OMC detected in the stratum corneum and the penetration depth are strongly dependent upon the formulation's nature, the particle size, and the type of enhancer. |
