Abstract
Description
Die Erfindung betrifft plättchenförmige Pigmente, insbeson dere für kosmetische Anwendungen. Plättchenförmige Pigmente, d. h. Materialien, mit einer im Vergleich zu Länge und Breite relativ geringen Dicke, wie z. B. Glimmerplättchen, die mit Metalloxiden oder Farbstoffen beschichtet sind, finden sowohl zur Pigmentierung von Lacken, Farben, Kunststoffen und der gleichen als auch in kosmetischen Zubereitungen Verwendung. Für manche Anwendungen ist der starke Perlglanz derartiger Präparationen unerwünscht. Weiterhin ist, besonders für kosmetische Anwendungen, nachteilig, daß Präparationen mit derartigen Pigmenten nicht die wünschenswerten weichen taktilen Eigenschaften aufweisen. Diese können zwar durch weitere Zusätze verbessert werden.The invention relates to platelet-shaped pigments, in particular for cosmetic applications. Platelet-shaped pigments, d. H. Materials, with a compared to length and width relatively small thickness, such as. B. mica platelets with Metal oxides or dyes are coated both for pigmenting paints, paints, plastics and the same as well as use in cosmetic preparations. For some applications, the strong pearlescent is more Preparations undesirable. Furthermore, especially for cosmetic applications, disadvantageous that preparations with such pigments do not give the desirable soft have tactile properties. This can be done through further additives can be improved.
Dafür ist z. B. der Zusatz sphärischer Teilchen geeignet, wie er in der DE 39 22 178 überschrieben wird.For this, e.g. B. the addition spherical particles suitable, as described in DE 39 22 178 is overwritten.
Jedoch bleibt die Aufgabe bestehen, ins besondere für kosmetische Anwendungen Pigmente mit einem matten satin-artigen Glanz und angenehm weichen taktilen Eigenschaften bereitzustellen. Überraschenderweise wurde gefunden, daß plättchenförmige nitridische Materialien sich sehr gut zur Herstellung von Schicht-Substrat-Pigmenten eignen. However, the task remains, ins special for cosmetic applications pigments with a matt satin-like sheen and pleasantly soft tactile Provide properties. Surprisingly found that platelet-shaped nitride materials very good for the production of layer-substrate pigments own.
Die erfindungsgemäße Aufgabe wird also durch die Bereit stellung neuartiger Pigmente aus nitridischem Material, die mit mindestens einem Farbstoff und/oder einem Metalloxid beschichtet sind, gelöst. Gegenstand der Erfindung sind daher plättchenförmige Pigmente aus einem nitridischen Material, das mit mindestens einem Farbstoff und/oder einem Metalloxid beschichtet ist.The task according to the invention is thus accomplished by provision of novel pigments made of nitride material, the with at least one dye and / or a metal oxide are coated, solved. The subject of the invention are therefore platelet-shaped pigments made of a nitride material, that with at least one dye and / or a metal oxide is coated.
Die erfindungsgemäßen Pigmente enthalten ein Nitrid, wie z. B. Aluminium- oder Bornitrid als Träger. Dabei ist Bornitrid (BN) als Trägermaterial bevorzugt. Bevorzugt wird plättchen förmiges BN. Dieses wird nach bekannten Verfahren herge stellt. Hinweise auf geeignete Herstellverfahren sind in Handbüchern, z. B. Ullmann′s Encyclopedia of Industrial Chemistry, Band A 4, 5. Auflage (1985); Verlag Chemie, und in der Patentliteratur, z. B. DE 19 43 582, zu finden. Partikel mit folgenden Abmessungen werden bevorzugt. Dicke 0,02-0,5 µm; Durchmesser 8-40 µm; besonders bevorzugt sind Partikel mit den Abmessungen 0,08-0,13 µm Dicke und 15-25 µm Durchmesser.The pigments of the invention contain a nitride, such as. B.

- a) 10 g Carmin gelöst in 150 ml H2O (mit NaOH auf pH 11,0 eingestellt),a) 10 g of carmine dissolved in 150 ml of H 2 O (adjusted to pH 11.0 with NaOH),
- b) 5 g AlCl3·6 H2O gelöst in 150 ml H2O.b) 5 g AlCl 3 .6 H 2 O dissolved in 150 ml H 2 O.
Das Reaktionsprodukt wird abgesaugt, mit 8 l H2O gewaschen, bei 80 °C getrocknet, mittels einer Culatti-Mühle zerkleinert und gesiebt (63 µm Maschenweite).The reaction product is filtered off with suction, washed with 8 l of H 2 O, dried at 80 ° C., crushed using a Culatti mill and sieved (63 μm mesh size).
Das derartig hergestellte rote Pigment besitzt angenehme taktile Eigenschaften.The red pigment produced in this way is pleasant tactile properties.
In einer Rührwerksapparatur wird unter Rühren (1200 UpM) eine Suspension von 50 g BN (Teilchengröße: Durchmesser 20 µm, Dicke 0,1 µm) in 2 l H2O auf 75°C erwärmt (pH 7,0). Anschließend wird der pH mit HCl (5 g/l) auf 8,0 eingestellt. Dann werden im Laufe von 5 Stunden 800 ml einer wäßrigen Lösung enthaltend 100 g KCr(SO4)2·12 H2O zugefügt; dabei wird der pH durch Zugabe von Ammoniaklösung (125 g/l) auf 6,0 gehalten. Nach der Zugabe der Chromsalzlösung wird 15 Minuten weiter gerührt. In a stirrer apparatus, a suspension of 50 g BN (particle size: diameter 20 μm, thickness 0.1 μm) in 2 l H 2 O is heated to 75 ° C. (pH 7.0) with stirring (1200 rpm). The pH is then adjusted to 8.0 with HCl (5 g / l). 800 ml of an aqueous solution containing 100 g of KCr (SO 4 ) 2 .12 H 2 O are then added in the course of 5 hours; the pH is kept at 6.0 by adding ammonia solution (125 g / l). After the addition of the chromium salt solution, stirring is continued for 15 minutes.
Das Reaktionsprodukt wird abgesaugt, mit 10 l H2O gewaschen, bei 120°C getrocknet, anschließend 30 Minuten bei 800°C geglüht und gesiebt (63 µm Maschenweite).The reaction product is filtered off, washed with 10 l of H 2 O, dried at 120 ° C., then annealed at 800 ° C. for 30 minutes and sieved (63 μm mesh size).
Das Produkt ist ein grünes Pigment mit einem Chromoxidgehalt von 23% und mit sattem Farbtcn und seidig-mattem Glanz, sowie mit angenehmen taktilen Eigenschaften.The product is a green pigment with a chromium oxide content of 23% and with rich colors and silky matt gloss, as well as with pleasant tactile properties.
