Abstract
nanocápsulas poliméricas deformáveis no encapsulamento de bioativos. a presente invenção refere-se a uma nanocápsula deformável compreendendo uma parede polimérica de poli (d,l-lactídeo) (pla) e um núcleo oleoso de palmitado de retinila que compreende um ou mais princípios ativos lipofílicos solúveis com característica de deformação, baixo índice de polidispersão, maior diâmetro comparadas com nanoesferas, alto índice de eficiência de encapsulamento, estáveis, elásticas e de baixa citotoxicidade. dessa forma, o objeto da presente invenção pode ser de grande interesse para sistemas de liberação sustentada de fármacos ou ativos cosméticos por indústrias farmacêuticas e cosméticas.deformable polymeric nanocapsules in the encapsulation of bioactives. The present invention relates to a deformable nanocapsule comprising a polymeric wall of poly(d,l-lactide) (pla) and an oil core of retinyl palmitate comprising one or more soluble lipophilic active principles with low deformation characteristic of polydispersion, larger diameter compared to nanospheres, high encapsulation efficiency, stable, elastic and low cytotoxicity. thus, the object of the present invention may be of great interest for sustained release systems for drugs or cosmetic actives by pharmaceutical and cosmetic industries.
