Production of Carboxymethyl Cellulose Films Incorporating Rue (Ruta graveolens) Essential Oil

Carboxymethyl cellulose (CMC) is considered a non-toxic, biodegradable and biocompatible polymer. CMC-based films are rated as flexible, clear, odorless, moderately tear resistant, resistant to oil grease migration, water soluble. Due its hydrophilicity, CMC can serve matrix encapsulate hydrophobic substances, like essential oils, by emulsion dispersions. The of rue (Ruta graveolens) has antifungal, antimicrobial, insecticide therapeutic properties already reported in the literature. For incorporation films, ultrasound-assisted technique was used. were produced casting evaporation. polymeric with emulsified evaluated according droplet size, chemical composition, morphology thermogravimetric profile. size obtained for 229.1 nm. showed good transparency, regularity characteristics similar those pure
