The andiroba oil extracted of Carapa guianensis has attracted considerable interest by the pharmaceutical and cosmetic industries because of its anti-inflammatory and insect repellent properties. This research evaluated the in vitro and in vivo andiroba oil photoprotection activity. Stable O/W emulsions with ethylhexyl methoxycinnamate were prepared with and without andiroba oil. These emulsions were assessed by evaluating several parameters such as macroscopic analysis and organoleptic aspects, emulsion type by diluition test and in vitro and in vivo determinations of Sun Protect Factor (SPF). The in vitro SPF was determined according to the spectrophotometric method developed by Mansur. The in vivo SPF values were determined according to the Food and Drug Administration (FDA) method. There was not statistical difference among the formulations, demonstrating that the andiroba oil did not present photoprotective activity.
