Nano titanium dioxide is a chemically inert and transparent substance with many important & diversified applications in paints & coatings and cosmetics. It has average particle size of less than 100nm with good thermal & chemical stability. Due to the smaller size of particles and higher surface area, nano titanium dioxide finds practice in many sectors. It is commonly found in products such as cosmetics, paints & coatings, pigments, plastics, and many others. It also finds utilization in a series of environmental and biomedical applications, such as photocatalytic degradation of pollutants, water purification, biosensing, and drug delivery. The nano titanium dioxide market accounted for $4,486 million in 2015 and is projected to reach $16,682 million by 2022, registering a CAGR of 20.7% from 2016 to 2022.
