Sistemas Nanoestruturados Contendo Óleo De Linhaça: Desenvolvimento Tecnológico E Caracterização Físico-Química De Nanoemulsões E Nanocápsulas Poliméricas

Abstract: Objetivo: O óleo de linhaça apresenta diversas propriedades terapêuticas, principalmente devido à presença de ácidos poli-insaturados em sua composição. Para melhor eficácia e/ou aumento da estabilidade de óleos vegetais farmacologicamente ativos, sistemas nanoestruturados são desenvolvidos para veiculação deste tipo de substância. Este estudo objetivou desenvolver e caracterizar sistemas nanoestruturados contendo óleo de linhaça. Foram preparadas nanocápsulas poliméricas e nanoemulsões, avaliando-se duas conc… Show more

“…The nanoemulsion (NTrEO) prepared from the essential oil of Tetradenia riparia (TrEO) showed the best hydrophilic-lipophilic balance (HLB) was 15.5 (Supplementary Materials: S1 Table ), showing a milky white color with a slightly bluish reflection, without observation of separation of phases or any parameter that indicated instability of the formulation, such as those described by Silva [24], as shown in Figure 2. Light scattering in nanoscale colloidal systems causes a characteristic bluish reflection called the tyndall effect and represents a parameter indicative of stability kinetics acquired by nanoemulsions compared to macroemulsions [25]. The best results were obtained with the nanoemulsion prepared with polysorbate 80 and polysorbate 20 as a surfactant (HBL 15.5).…”

“…A nanotecnologia vem se desenvolvendo consideravelmente ao longo dos anos e as pesquisas nessa área trouxeram inovações no mercado de desenvolvimento de produtos (STROHER, ARMIJO e RAFFIN, 2010;TEIXEIRA et al, 2014). Nesse contexto, os sistemas nanoestruturados possuem uma área de superfície elevada, o que favorece o aumento da resposta terapêutica (ASSIS et al, 2012) e são capazes de controlar a liberação dos ativos/fármacos incorporados, protegendo-os da degradação química, física e enzimática (BRUXEL et al, 2012;RIGON et al, 2017).…”
