Abstract
Official abstract text for this publication.
The present invention relates to a cosmetic formulation including a cosmetically acceptable medium and at least one silver-colored pigment, the silver-colored pigment including a nonmetallic platelet-shaped substrate and at least one ilmenite-containing coating.
First claim
Opening claim text (preview).
The invention claimed is: 1. A cosmetic formulation comprising a cosmetically acceptable medium and at least one silver-colored pigment, the silver-colored pigment having a metallic character or effect and comprising a nonmetallic platelet-shaped substrate, at least one titanium oxide layer, and at least one ilmenite-containing coating, wherein the amount of iron compounds, calculated as elemental iron, in the pigment is less than 5.0% by weight, based on the total weight of the silver-colored pigment, wherein the at least one ilmenite-containing coating has a concentration gradient which decreases in the substrate direction, and wherein the silver-colored pigment has a flop intensity F i , defined as the product of flop index and glitter intensity S—i as a function of the average particle size D 50 , in accordance with formula (II) Flop intensity ( F i ) = Flop index · S_i D 50 , ( II ) of at least 10. 2. The cosmetic formulation according to claim 1 , wherein the silver-colored pigment has an iron(III) oxide content of less than 0.5% by weight, based on the total weight of the pigment. 3. The cosmetic formulation according to claim 1 , wherein the chroma of the silver-colored pigment with a measurement geometry of 110°, relative to the angle of emergence of the light irradiated at 45°, is C* 110 <2.4. 4. The cosmetic formulation according to claim 1 , wherein the-ilmenite-containing coating layer of the silver-colored pigment has an average layer thickness in a range from 1 nm to 20 nm. 5. The cosmetic formulation according to claim 1 , wherein the silver-colored pigment has an iron/titanium weight ratio as a function of the coating, in accordance with formula (I) Iron content ( % by weight ) Titanium content ( % by weight ) · Fraction of the coating ( % by weight ) , ( I ) in a range from 1 to 8, where “iron content” stands for the amount of iron compounds, calculated as elemental iron, and “titanium content” stands for the amount of titanium compounds, calculated as elemental titanium, in each case in the pigment and based on the total weight of the silver-colored pigment, and where the “fraction of the coating (% by weight)” stands for the weight fraction, based on the total weight of the pigment, of the coating applied to the substrate. 6. The cosmetic formulation according to claim 1 , wherein the silver-c
