Desenvolvimento e caracterização de micropartículas poliméricas contendo extrato de Ruta graveolens L. para veiculação em formulação de xampu infantil

Abstract: O objetivo do presente estudo foi desenvolver, caracterizar e quantificar micropartículas de poli(ԑ-caprolactona) contendo extrato de Ruta graveolens L. para posterior veiculação em um xampu infantil para o combate seguro da pediculose. O extrato hidroalcóolico foi obtido da planta seca através do método de turbólise. As micropartículas foram obtidas pelo método da emulsão simples seguida da evaporação do solvente modificando a proporção de extrato e polímero.  Os sistemas poliméricos foram caracterizados por … Show more

“…The zeta potential values of the formulations indicate a good stability in suspension, since the values were close to -30 mV, values that indicate a good colloidal stability due to an electrostatic repulsion between the nanoparticles, so the nanoparticles tend not to aggregate. Nanoparticles with zeta potential values of approximately (±) 30 mV are more stable in suspension(Camargo et al, 2023;Mohanraj;Chen, 2006). …”
