Embodiment 1

[0084] Preparation of Component A

[0085] Use 300-330 g of TiCl with a pH of 2-2.5 4 Solution (400g TiCl 4 / l) coating and subsequent application of 300-310 g of sodium water glass (13-15% by weight of SiO) with a pH of 7.8-8.2 2 ) coated with 200g of D 90 Spherical SiO with a value of 4-8 μm 2 particles, and then stir the mixture. In each case TiO 2 and SiO 2 The amount of sedimentation is 12-16% by weight, based on the total weight of the coated white particles.

[0086] Preparation of Component B

[0087] In parallel, in another reaction vessel, 200 g of TiCl with a pH of 2-2.5 4 Solution (400g TiCl 4 / l) coating and subsequent application of 100-130 g of FeCl with a pH of 3-3.5 3 solution (218g of FeCl 3 ) coated with 100g of D 90 Spherical SiO with a value of 4-8 μm 2 particles, and then stir the mixture. The desired color (from ocher yellow to reddish) is set by field measurement of the Lab values. TiO 2 and Fe 2 o 3 The precipitated amounts of ® a...

Embodiment 2

[0093] A mixture of component A and component B as described in Example 1 can be adjusted in terms of color by selecting the calcination temperature. The starting temperature is 600-750°C, the hue shifts more and more from pink / brown / apricot to yellow until from 700°C the final product appears yellowish / white. Here brookite (Fe 2 TiO 5 ) began to form.

[0102] Lubrajel DV (6) Propylene Glycol, Polyglyceryl Methacrylate 5.00

[0103] preparation:

[0104] Dissolve the aloe vera powder in the water of phase A, then add all the pigments and pigment mixture and the remaining ingredients except Carbopol and disperse. Acidify with a few drops of citric acid to reduce viscosity, then disperse in Carbopol with stirring. When completely dissolved, stir slowly (not homogenize) in the pre-dissolved phase B, then add phase C. Adjust the pH to between 7.0-7.5 with citric acid solution if necessary.

[0105] A water-based eyeshadow gel formulation containing aloe vera (extremely fast drying and easy to apply with fingers) was obtained.

Abstract

The present invention relates to a pigment mixture based on spherical particles having a defined particle-size distribution, and to the use thereof in paints, coatings, printing inks, security printing inks, plastics, ceramic materials, glasses, in cosmetic formulations, as tracer, as filler and for the preparation of pigment preparations and dry preparations.

Description

technical field [0001] The invention relates to a pigment mixture based on spherical particles with a defined particle size distribution and to its use as tracer in paints, coatings, printing inks, security printing inks, plastics, ceramic materials, glass, in cosmetic formulations , as a filler and for the preparation of pigment preparations and dry preparations. Background technique [0002] The term pigment applies to colorants which are insoluble in the application medium. Typical examples of organic pigments are phthalocyanines, diketopyrrolopyrroles, azo pigments, and quinacridones. Among the inorganic pigments there may be mentioned various types of iron oxides or also ultramarine blue. Pigments are generally distinguished from dyes which are soluble in the application medium by their higher chemical and photochemical stability. [0003] Fillers can be regarded as a special form of pigments. In the case of fillers, the "coloring" function is not the highest priori...
