PREPARATION OF NEW NANOCOMPOSITES CONTAINING NANOEMULSIONS OF MELALEUCA, COPAIBA AND LEMON OIL FOR APPLICATION AS BIOMATERIAL

The sodium alginate is a linear polymer used in industry and in medicine for many applications such as dressings for wounds, due to low toxicity and maintains a proper moist environment. The essential oils are materials that have antimicrobial activity and are active materials, which may be incorporated in polymeric films. This study has as objective the produce alginate films incorporated with nanoemulsions of melaleuca, copaiba and lemon oil and investigate water vapor permeability (WVP) analysis of the films, particle size and zeta-potential of nanoemulsions. Particle size analyzes showed formation of large and small particles nanoemulsion depending on the agitation speed used during production of nanoemulsions. Results of the WVP analyzes showed that the film with alginate 3 % w/v and nanoemulsions with little particle prepared with agitation speed of 15000 rpm showed better WVP. Produced films show good quality for a future application as dressings because it has good WVP. This is very interesting because the skin needs to breathe.
