When the pH of titanium dioxide deviates from the optimal range, its properties and performance may be compromised. For example, at low pH levels (acidic conditions), titanium dioxide particles tend to agglomerate and form clusters, leading to poor dispersion and reduced whiteness. On the other hand, at high pH levels (alkaline conditions), the stability of titanium dioxide can be compromised, resulting in decreased opacity and color performance.

While loose titanium dioxide presents a problem, titanium dioxide within sunscreen formulations presents a much safer option than conventional sunscreen chemicals like oxybenzone and octinoxate. However, titanium dioxide may become dangerous when it is nanoparticle size. Generally, nanoparticles can be 1000 times smaller than the width of a human hair. Despite nanoparticles becoming increasingly common across industries, they have not been properly assessed for human or environmental health effects, nor are they adequately regulated. Researchers don’t quite understand the impacts nanoparticles could have on human health and the environment. However, because of their infinitesimally small size, nanoparticles may be more chemically reactive and therefore more bioavailable, and may behave differently than larger particles of the same substance; these characteristics may lead to potential damage in the human body or ecosystem.
