【 摘 要 】

The use of orange oil presents as an ecological alternative to chemicals, attracting the attention of the scientific community to the development of eco-friendly antimicrobials. The microencapsulation technology has been used for the application of orange oil to textiles, being an economically viable, fast and efficient method by combining core and shell materials, desirable perceptual and functional characteristics, responsible for properties related to the nature of the product and provides that the wall materials release the functional substances in a controlled manner, in addition to effectively protecting and isolating the core material from the external environment to prevent its volatilization and deterioration, increasing the stability of the oil, such as non-toxicity. Thus, to better exploit the properties of the orange essential oil applied to textile products this study presents a characterization of microcapsules of Melamine formaldehyde obtained by the interfacial polymerization method with variations of proportions of orange oil (volatile) with fixed oil Medium-Chain Triglycerides (MCT) (non-volatile) to assist in the stability of the orange essential oil. Scanning electron microscope (SEM) was used as visualizing tool to characterize microparticles and surface morphology and thermal characteristics of microcapsules were premeditated by mean Differential scanning calorimetry (DSC).
