| Pigmentary grade Titanium Dioxides and Iron Oxides (red, yellow & black) are widely
used for color cosmetics and have primary particle sizes greater than 0.2 microns. Pigmentary grade
pigments also tend to aggregate in formulas. Color strength, gloss and opacity are related to
the particle
size of the aggregates. Theoretically, the color intensity is highest (or most opacity) is
obtained when
the dispersion particle size (in formulas) is closest to their primary particle size.
Organic lakes dispersions are also available.
