Resumen
CORREA GONZALEZ, Yuly X et al. Propolis based lipid nanoparticles as carriers of cosmetic actives: Development, characterization and safety evaluation. Rev. colomb. cienc. quim. farm. [online]. 2016, vol.45, n.1, pp.147-168. ISSN 0034-7418. https://doi.org/10.15446/rcciquifa.v45n1.58026.
In the cosmetic field, the technology at the nanometric scale is attractive for designing novel and functional products. In the case of lipid nanoparticles, the ability of these carriers for increasing the stability of active molecules and modifying their release has been demonstrated. As a contribution in the research of innovative alternatives for preparing these particles, this work proposes the use of the propolis waxes as starting material. In this way, lipid nanoparticles containing tea tree oil were prepared having particle sizes close to 200 nm with polydispersity indexes less than 0.1. The zeta potential values near to zero suggest the stabilization of the lipid nanoparticles via steric mechanisms. The incorporation of the active into the nanoparticle structure is confirmed by DSC. As a whole, the results are appealing in order to give added value to beehive product, recognized in Latin America for its biological properties. Furthermore, these results offer a new alternative of lipid material which is interesting for developing pioneering cosmetic products containing active molecules.
