In order to obtain the textile materials with potential for use in the treatment of inflammatory skin conditions, this studyapproached the laboratory experiments related to depositing by padding of oil-in-water emulsions type based onchitosan-propolis-cinnamon essential oil. In this regard, seven experimental variants of emulsions were prepared andthen characterized by specific methods from physical-chemical and stability point of view. The chitosan-propolis-cinnamon essential oil-based emulsions were then immobilized on a knitted textile structure from 100% organic cotton.The functionalized textile materials were characterized from morphological and antibacterial activity point of view. pHvalues obtained for the synthesized polymeric systems were in the range 4.67–4.88 and electrical conductivity of theemulsions increases with the concentration of the hydrophilic phase in the system, the highest values were registeredfor the emulsion code R4CSP developed with the smallest volume fraction of water. The stability index over a period of10 days indicated that emulsions are stable, not showing the presence of one of the flocculation, creaming /sedimentation, coalescence or Ostwald ripening phenomena. The highest values of emulsifying activity index wereobtained for the R7CSP, emulsion developed with the smallest volume fraction of water. The highest value of viscositywas obtained for the experimental variant R4CSP in which the highest volume fraction of chitosan and the smallestvolume fraction of water were used. The textile materials treated with synthesized emulsions based on chitosan-propolis-cinnamon essential oil have antibacterial effect against the S. aureus test strain, with inhibition zones between1.5 mm (R2CSP and R7CSP) and 4 mm (R6CSP).
