barium sulphate is soluble in water
Titanium dioxide, in its anatase phase, is recognized by its E-number E171 in the European Union and is used as a colorant, whitening, and brightening agent in various food products. It enhances the appearance and texture, providing a pure white color to confectionery, bakery goods, dairy products, and even beverages. Moreover, its UV blocking capabilities protect food from color degradation, extending their shelf life.
Leading producers of anatase titanium dioxide have invested heavily in research and development to optimize their production methods. These companies employ advanced technologies like the chloride process or the sulfate process to synthesize high-purity anatase particles with consistent quality. They also focus on environmental sustainability, striving to reduce energy consumption and minimize waste during production.
One of the most significant contributions of chemical product manufacturers is in the field of healthcare. Pharmaceutical companies develop life-saving drugs and treatments that combat diseases and improve quality of life. Without these advancements, many of us would not be able to enjoy the health and longevity that we do today.
The Power of Antioxidants
Infrared analysis showed that the characteristics bands for the bare nanoparticles are still exhibited in the vitamins@P25TiO2NPs spectra, such as a wide peak in 450–1028 cm−1 related to the stretching vibration of Ti-O-Ti and other peaks in 1630 cm−1 and 3400 cm−1, which represent the surface OH groups stretching. The IR spectrum of vitaminB2@P25TiO2NPs showed signs of binding between compounds. The OH bending peak (1634 cm−1) corresponding to bare nanoparticles disappeared, and the NH2 bending band characteristic of vitamin B2 appeared (1650 cm−1). The IR spectrum of vitaminC@P25TiO2NPs also showed signs of successful functionalization. Bands at 1075 cm−1; 1120 cm−1; 1141 cm−1 were observed, which are originated by C
O-C vibrations present in the vitamin C. The intense band at 1672 cm−1 is attributed to the C = O stretching in the lactone ring while the peak at 1026 cm−1 is ascribed to the stretching vibration Ti-O-C. Wide bands at 3880–3600 cm−1 are related to stretching vibration OH groups, but those disappear in the modified nanoparticles spectrum. These observations confirm the interactions between the P25TiO2NPs and the vitamins [35].
