Simazine is 1,3,5- triazine herbicide molecules (an organic herbicide). Its technical and formulation was found to stabilize against UV light and sunlight by using Titanium dioxide as UV Stabilizer. Successful use of inorganic UV stabilizer in the pesticide formulations, like Simazine is UV unstable herbicide , which degrades by sunlight and UV rays exposer. Titanium dioxide (TiO2) is well known UV stabilizer used in cosmetics and plastic industry very widely for the stabilization. Brown PET (Polyethylene Ter phthalate) bottles as packaging materials plays important role in stabilizing the technical and it’s formulations along with the TiO2 as UV stabilizer as compared to the white HDPE bottles.
