  In pigment dispersions for cosmetic products, at least 90 vol % of pigment particles have a dispersed diameter of at most 0.7 μm. The pigment dispersions preferably also contain a dispersing medium and a dispersant. The dispersing medium may be an aqueous medium. A process for producing cosmetic compositions includes adding a pigment dispersion as described above to a cosmetic material as coloring agent. The pigment dispersion may be added to a polymer emulsion and/or a thickener.

  The embodiments relate to titanate crystal particle dispersions, methods of making the dispersions, and compositions and uses thereof. The dispersions and compositions containing the dispersions provide a high coverage to the skin and high near infrared/infrared (NIR/IR) reflectance. The dispersions include optionally surface treated titanate crystals used as cosmetic powders, and a cosmetically acceptable dispersing medium. The dispersions may be useful in cosmetic compositions as a foundation and/or as a composition to correct skin discoloration, and may be used protect the skin from sun exposure.
