Materials having a Pigments treated with jojoba ester are almost completely large range of sizes, for example from about 5 nm to 300 nm odorless, as compared to other treatments such as carnauba or larger, as Well as Various shapes, for example, without 5 wax which have relatively strong odors. Likewise, when sub limitation, spherical and acicular, may be treated. For jected to high temperatures, such as 90° C., for a relatively example, materials that may be advantageously treated in long time, such as six hours, pigments, such as titanium accordance with the present invention include microparticles dioxide and seracite exhibit virtually no odor change, of the metal oxide titanium dioxide (TiO) (micro TiO) whereas pigments treated with Such materials as carnauba having a primary particle size of less than about 200 nm and 10 a pigmentary grade size (i.e., larger particle size) of greater and lauroyl lysine exhibit odor increases in the range of about than about 200 nm, with an alumina coating such as that sold 30 to 90%. Thus, pigments treated with these other materials by ISK under the trade name TTO-S-3. TTO-S-3 has a pri have odor levels dozens of times greater than pigments treated mary particle size of about 15 nm and has an acicular shape.
