Abstract

The human skin exposure to sunlight can cause damage such as erythema, cancer and premature aging of the skin. One of the ways to protect the skin and, consequently, decrease these effects, is the use of sunscreens, as the Octyl Methoxycinnamate (OMC) witch has been very used in photoprotective formulations because of their spectrum against Ultraviolet Radiation (UV) B. For action of sunscreen, it is extremely important to their permanence in the outer layers of the epidermis. However, some studies have detected the OMC in samples of blood, urine and milk after topical application of conventional formulations containing this filter, indicating systemic exposure.In this way, it becomes convenient the study an appropriate carrier which allow adequate dermal retention for this filter. Nanostructured lipid systems, such as Nanostructured Lipid Carriers (NLCs) are gaining notoriety as carriers for dermal administration due to its ability to interact with the stratum corneum, allowing greater retention of active substances. Thus, the incorporation of OMC in NLC may be convenient, in order to favor the persistence of this filter in the upper layers of the skin and hence promote greater protection against UV rays. In this project we intend to develop, characterize and evaluate the in vitro biological effects of incorporation of OMC in NLCs, in order to optimize its photoprotective effect and its preventive action against skin aging and cancer.
