Abstract This work reports studies on the production of eugenol-loaded microspheres by solvent evaporation method, targeted for incorporation into textile substrates, using different cellulose derivatives: ethyl cellulose, acetate (CA), butyrate acetate, and phthalate. The were evaluated in terms size, shape, thermal stability, encapsulation efficiency, eugenol kinetics release. CA-based proved to be best, thus being selected subsequent experiments. Comparable properties achieved ongoing from 100 mL higher batch volumes (up 2000 mL). successfully incorporated cotton fabrics a padding technique, confirmed FE-SEM. Eugenol release profiles impregnated textiles demonstrated slow controlled (less than 20% encapsulated amount over 90 days). developed most promising retention protection hydrophobic active compounds possible applications.
