Formulation changes in the form of altered surface treatments are known to frequently occur for a

variety of commercialized particle-types. The R-100 formulation of rutile-type titanium dioxide is a

well-known low-toxicity particulate. This study was designed as a pulmonary screening tool to

determine whether Pigment A TiO
