Publications summarizing the results of studies on the effect of pigments on the skin and mucous membrane (conjunctiva of eyes) of rabbits describe similar observations. These sources refer to pigments as trade products which may contain auxiliaries (Table 37).

The photoprotective effect of pigments depends on their particle size, which in turn affects their radiation absorption and scattering properties. For example, the optimum particle diameter for titanium dioxide is about 200 nm according to the manufacturer (16). A point that has to be considered in this context is that a loss of the photoprotective properties of the pigments may result from secondary agglomeration. Consequently, pigments are most effective if they are evenly distributed over the surface of the individual photosensitive drug particles in the tablet (Thoma K, Aman W. In preparation) (4).

Since the viscoelastic and creep properties of polymeric materials are often correlated with their glass-transition temperatures (Tg) [40], we considered that DSC would be a useful technique to investigate commercial maxillofacial materials. In our pioneering study [41], the effects of pigments on the DSC plots were studied for a heat-polymerized maxillofacial silicone (MDX 4-4515, Dow Coming, Midland, MI, USA), which served as a model material.

Because cut edges are crucial areas of coil-coated material and can be used to study the effect of pigments in organic coatings on the corrosion in defects, they have been extensively studied by means of different electrochemical techniques such as electrochemical impedance and scanning vibrating electrodes [102, 139,140].
