Still many experts say the body of research does not support the current health concerns being expressed about titanium dioxide.
Other food manufacturers use titanium dioxide to absorb water and keep moisture from clumping or degrading, Paul Westerhoff, PhD, an environmental engineer at Arizona State University who researches the biological and cellular effects of titanium dioxide, told Health.
EFSA’s scientific advice will be used by risk managers (the European Commission, Member States) to inform any decisions they take on possible regulatory actions.
Finally, research has shown that titanium dioxide nanoparticles do not pass the first layer of the skin — the stratum corneum — and are not carcinogenic (7Trusted Source, 15Trusted Source).
Buff percentage refers to the amount of uncoated or partially coated titanium dioxide particles in a product. A higher buff percentage generally indicates a lower level of coating, which can impact the overall performance of the titanium dioxide. Manufacturers must carefully control this percentage to ensure that their product meets the specific requirements of their customers.
