Definitions
- the present application relates to a pigment suspension comprising a pigment and a carrier medium.
- a further object is a cosmetic product which was produced using the pigment suspension and an organosilicon compound.
- Pigments are often used in coatings, paints, printing inks, powder coatings, cosmetics or plastics for coloring. Paints, varnishes, printing inks, cosmetics and powder coatings are liquid or powdered coating materials that are applied to surfaces in order to obtain both improved or modified optical and physical properties.
- Oxidation colorants are usually used for permanent, intensive colorations with good fastness properties and good gray coverage. Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components, which form the actual dyes with one another under the influence of oxidizing agents such as hydrogen peroxide. Oxidation coloring agents are characterized by very long-lasting coloring results.
- color pigments are generally understood to mean insoluble, color-imparting substances. These are present in undissolved form in the form of small particles in the coloring formulation and are only deposited from the outside on the hair fibers and/or the surface of the skin. Therefore, they can usually be removed without leaving any residue with 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, to color paints, printing inks, inks,
- Plastics, glasses, ceramic products and preparations for decorative cosmetics such as nail polish are characterized above all by their attractive angle-dependent color impression (goniochromism) and their metal-like luster. Hair with a metallic finish or metallic reflections is trendy. The metallic tone makes the hair appear thicker and shinier.
- the pigments are made available to the user in a form that is stable on storage and can be metered. This can be done in particular in the form of a storage-stable pigment suspension.
- Ground pigment powder and water are usually used to produce inorganic pigment suspensions. It may be necessary to add small amounts of organic or inorganic dispersing agents.
- Some pigments for example so-called metallic effect pigments, are only of 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 metallic pigment surfaces are conventionally protected by phosphating, chromating, silanizing or other coatings, for example made of synthetic resin.
- Such coated metal effect pigments are more expensive than uncoated metal effect pigments.
- pigment suspensions which can be produced easily and inexpensively and are stable on storage.
- the pigments in the pigment suspension should be stable against decomposition and/or corrosion.
- different types of pigments for example inorganic and organic pigments or inorganic and metallic pigments, could be used in the pigment suspension.
- pigment suspensions containing at least one phosphoric acid ester as a carrier medium meet these requirements.
- a first subject matter of the application is one comprising a) at least one color-providing compound from the group of pigments and b) a phosphoric acid ester.
- the pigment suspensions contain at least one coloring compound from the group of pigments as the first ingredient essential to the invention.

- the water solubility can be determined, for example, using the method described below: 0.5 g of the pigment is weighed out in a glass beaker. A stir bar is added. Then one liter of distilled water is added. This mixture is stirred on a magnetic stirrer for heated to 25 °C for one hour. If undissolved components of the pigment are still visible in the mixture after this period, the solubility of the pigment is below 0.5 g/L.
