US 2014/O 105947 A1 Apr. 17, 2014 0019. A variety of pigments may be used to make casted pigments which are treated with them. More particularly, pigments in accordance with the present invention. For titanium dioxide treated with jojoba ester gives the product a example, minerals such as talc, mica and sericite; metal feel which is as dry as untreated pigment, but which is very oxides such as titanium dioxide, Zinc oxide and iron oxides; Smooth and on a par with the Smoothness of the pigment thermoplastic powders; organic pigments such as starch and treated with hydrogenated lecithin and Stearic acid. cellulose; and other inorganic pigments may be used. Mate 0026 Jojoba ester treated sericite also scores very high on rials having a large range of sizes, for example from about 5 the Smoothness scale, comparable to hydrogenated lecithin nm to 300nm or larger, as well as various shapes, for example, treated pigment and Substantially more Smooth than the pig without limitation, spherical and acicular, may be treated. For ment treated with lauroyl lysine or lecithin. example, materials that may be advantageously treated in 0027 Pigments treated with jojoba ester are almost com accordance with the present invention include microparticles pletely odorless, as compared to other treatments such as of the metal oxide titanium dioxide (TiO) (micro TiO) carnauba wax which have relatively strong odors. Likewise, having a primary particle size of less than about 200 nm and when subjected to high temperatures, such as 90° C., for a a pigmentary grade size (i.e., larger particle size) of greater relatively long time, Such as six hours, pigments, such as than about 200 nm, with an alumina coating such as that sold titanium dioxide and seracite exhibit virtually no odor by ISK under the trade name TTO-S-3. TTO-S-3 has a pri change, whereas pigments treated with Such materials as car mary particle size of about 15 nm and has an acicular shape. nauba and lauroyllysine exhibit odor increases in the range of Tipaque PF-671 is an example of a pigmentary grade TiO, about 30 to 90%. Thus, pigments treated with these other having an alumina and silica coating and a particle size of materials have odor levels dozens of times greater than pig about 210 nm that may be treated in accordance with the ments treated in accordance with the invention, both before present invention.
