This work presents a green method for producing titanium dioxide nanoparticles. The resulting nanoparticles were characterized using DLS, XRD, FTIR. The resulting nanoparticles consist of an anatase phase with small impurities of  brookite and an amorphous phase associated with organic substances of the extract. Titanium nanoparticles exhibit high colloidal stability induced by rosehip extract. Due to their high colloidal stability, the nanoparticles proposed in this work are a promising resistor as one of the components for tuning the properties of hybrid materials in the PVDF matrix.
