The essential oil of pink pepper was obtained by hydrodistilation and characterized by GC-MS. The main components of this essential oil are: alpha-Phelandrene 35.84%, Limonene 17.31%, alpha-Pinene 1.98% (monoterpenes) and beta-Phelandrene 13.04%, o-Cymene 4.65%, delta-Cadinene 3.27%, trans-Caryophyllene3.04%, Bicyclogermacrene 2.13% (sesquiterpenes). The emulsions obtained are stable and the pH values of emulsions correspond to the natural pH of the skin, indicating that emulsions can be safely applied to the skin. Results from the optical microscopy analysis show that emulsions have a creamy and foam like appearance. All the emulsions present adequate Theological properties. Further microbiological tests and other analysis are necessary for the obtained emulsions.eninfo:eu-repo/semantics/closedAccesscollagenessential oilsnatural extractscelluliteArticle8147384WOS:000501994100008N/A
