Produção de nanopartículas a base do heteropolissacarídeo da goma de cajueiro (Anacardium Occidentale L.) e a aplicação em cosméticos.

Abstract

The present study evaluated the possibility of producing a nanosystem consisting of acetylated cashew tree gum heteropolysaccharide (PEJU) containing trapped Vitamin E, in addition to the feasibility of incorporating it into a serum-type cosmetic formulation. The production of the nanosystem was very successful, with a milky white appearance with bluish reflections, which matches the obtained diameter of 323 nm (±0.01), a high degree of homogeneity between the particles, polydispersity index (PDI) 0.158 ( ±0.01), its Zeta potential was -32.6 (±0.01), which predisposes the nanosystem to greater physical-chemical stability. Furthermore, it showed good performance after centrifugation for 15 min at 1500 rpm, and slight variation in the pH value on the day the nanosystem was made (4.96 ±0.2) and 15 days later (4.67 ±0.2) . The encapsulation efficiency was 96% (±0.5), indicating that PEJU was an excellent alternative for the production of the nanosystem, given its performance, innovative and eco-friendly characteristics, appreciated in current market trends. cosmetics. The incorporation into a serum-type cosmetic formulation had good results since in the stability screening test the pH had an average of 3.91 (±0.2), the density had an average of 1.058 x103sg and the average viscosity was 9.13 mPa.s (±0.71), which demonstrated good stability, with no incorporation of air into the formulation and no presence of lumps.
