The vitaminC@P25TiO2NPs, on the other side, did not have any effect on cell protection against ROS. This might be due to the fact that vitamin C, a well-known scavenger of ROS, could behave as prooxidant and even promote ROS and lipid peroxidation [39]. It was recently described that at small concentrations of vitamin C, the prooxidant effects dominate; while in large concentrations the antioxidant ones predominate [40]. The effect also depends on the cell state and the interaction of vitamin C with light. In this case, ascorbic acid may act as an antenna to harvest visible light when conjugated to P25TiO2NPs. Indeed, it was previously found that this combination (in some ratios) could have an improved photocatalytic activity, possibly due to a red shift in its light absorbance [41]. Further studies on vitaminC@P25TiO2NPs were not conducted, because of the poor antioxidant capacity [42].

Beyond its cosmetic role, TiO2 also acts as a UV stabilizer. It shields the nitrile gloves from the harmful effects of ultraviolet radiation, thereby increasing their longevity and maintaining their integrity under prolonged exposure. Moreover, it contributes to the gloves' opacity, preventing see-through and providing additional comfort and confidence to the wearer Moreover, it contributes to the gloves' opacity, preventing see-through and providing additional comfort and confidence to the wearer Moreover, it contributes to the gloves' opacity, preventing see-through and providing additional comfort and confidence to the wearer Moreover, it contributes to the gloves' opacity, preventing see-through and providing additional comfort and confidence to the wearertitanium dioxide for nitrile gloves factory.

Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.
