This study aims at encapsulation of essential oil as fragrances constituent used in perfumes and cosmetics in polymeric particles; potential application of oil encapsulated in hair cosmetic formulations assesstment and subsequent evaluation of its performance. The volatile oil used is obtained from Cymbopogon citratus plant, commonly known as West-Indian lemongrass, given the commercial availability and cultivation ease in the country and also the potential for use in fragrances, perfumes and cosmetic formulations.The first stage of the project consists of the essential oil volatile components chemical characterization by gas chromatography (GC) with mass spectrometry detector (MS). The encapsulation will take using in situ polymerization technique with melamine-formaldehyde. Then, the particles obtained will undergo a treatment with a cationic polymer derived from guar gum in order to increase the substantivity to the hair surface.Particles characterization will be held in order to its incorporation into hair shampoo and conditioner formulations. The fragrance persistence in hair tresses will be determined in relation to the essential oil volatile constituents evaluation according to the time of products application using the technique of solid phase microextraction (SPME) via headspace and GC/MS. Furthermore, it will seek to evaluate the encapsulated fragrance performance and maintenance as well as the product obtained effectiveness in avoiding the hair damage.
