Abstract
The microencapsulation of essential oils and its application in textile articles allows the aggregation ofdifferent functionalities to the substrates, imparting them antimicrobial properties, cosmetic effects, UVprotection, application of drugs, among others. Therefore, the coacervation technique allows goodresults using starch to prepare the microcapsules. The objective of this work was the microencapsula-tion of Aloe Vera with cornstarch using the simple coacervation technique in cotton nonwoven fabricusing butane tetracarboxylic acid (BTCA) as a binding agent. Optical and Scanning electron microscopywere performed to understand the morphology of the microcapsules obtained; thermogravimetry, tothe comprehension of the thermal degradation of the microcapsules; mass gain percentage; FTIR wasused to prove the interaction between nonwoven and microcapsule and finally, the CIE WI whiteindex. The micrography allowed the observation of granular morphology, predominantly angular. Thethermogravimetric curves have shown two significative thermal events: dehydration of the oil anddegradation of the starch. The samples presented darker coloration; however, their quality was notcompromised by the finishing. For this reason, the characterizations allowed to infer that the simplecoacervation using this method is a simple process, with good results for the encapsulation of essen-tial oils.
