Definitions
- Pigment suspension and cosmetic agent produced using the pigment suspension are Pigment suspension and cosmetic agent produced using the pigment suspension
- the present application relates to a pigment suspension comprising a pigment and a carrier medium.
- Another subject matter is a cosmetic agent which was produced using the pigment suspension and an organosilicon compound.
- Pigments are often used in lacquers, paints, printing inks, powder coatings, cosmetics or plastics for coloring. Paints, varnishes, printing inks, cosmetics and powder coatings are liquid or powdery coating materials that are applied to surfaces in order to obtain both improved or modified optical and physical properties.
- Oxidation dyes are usually used for permanent, intensive dyeings with good fastness properties and good gray coverage.
- Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components, which, under the influence of oxidizing agents such as hydrogen peroxide, form the actual dyes with one another.
- Oxidation dyes are characterized by very long-lasting coloring results.
- color pigments are generally understood to mean insoluble, coloring substances. These are present undissolved in the form of small particles in the coloring formulation and are only deposited on the outside of the hair fibers and / or the surface of the skin. Therefore, they can usually be removed without residue by a few washes with detergents containing surfactants. Various products of this type are available on the market under the name of hair mascara.
- Metallic luster pigments or metallic effect pigments are widely used in many areas of technology. They are used, for example, for coloring paints, printing inks, inks, plastics, glasses, ceramic products and preparations for decorative cosmetics such as nail polish. They are characterized above all by their attractive angle-dependent color impression (goniochromy) and their metallic-like sheen.
- the pigments are made available to the user in a storage-stable and meterable form. This can take place in particular in the form of a storage-stable pigment suspension.
- inorganic pigment suspensions For the production of inorganic pigment suspensions, ground pigment powders and water are usually used. It may be necessary to add small amounts of organic or inorganic dispersing aids.
- Some pigments for example so-called metallic effect pigments, have only limited stability in an aqueous medium.
- aluminum-based metallic effect pigments decompose comparatively quickly in water with the formation of hydrogen and aluminum hydroxide.

- the solubility of the pigment is below 0.5 g / L.
