Resumo
This study focused on the production of Aloe vera oil (AEO) microcapsules using chitosan (Ch) and arabic gum (AG) as biopolymers to produce
microcapsules. The variation of the components, such as the type of surfactant (Tween 20 or Span 80) and the molecular mass of chitosan,
resulted in different characteristics in the final particles. Microcapsules produced with Tween 20 showed larger size and lower uniformity than
those produced with Span 80. High molecular mass chitosan resulted in smaller microcapsules. Optical microscopy confirmed the formation of the
microcapsules, and the stability of the microcapsules was influenced by particle size and zeta potential, with an inverse relationship between these
properties. Fourier Transform Infrared Analysis (FTIR) analyses confirmed the functionalization of the microcapsules in 100% cotton half-mesh
fabrics, and scanning electron microscopy (SEM), evidenced the formation of covalent bonds between the microcapsules and the cotton fibers. This
bond ensures greater stability and encapsulation efficiency. The controlled release of the encapsulated AEO in the cotton fabric was influenced by the
type of crosslinking agent and the molecular mass of chitosan. Microcapsules crosslinked with 1,2,3,4-butanetetracarboxylic acid (BTCA) showed
a more consistent release, while those crosslinked with glutaraldehyde provided a slower and more controlled release, ideal for applications that
require the gradual release of the active ingredient. This study demonstrated the feasibility of producing AEO microcapsules using chitosan and gum
arabic. The properties of the microcapsules can be adjusted by varying the formulation components, allowing the development of controlled release
systems with applications in various segments, such as the textile industry.
