Pigment mixtures for cosmetics
Provided is a pigment composition comprising a first and second effect pigments, wherein the composition has a hue comparable to carmine but does not comprise carmine.
1. A UV-stable pigment composition comprising:
a first effect pigment and a second effect pigment,
wherein the first effect pigment comprises a substrate and at least one layer comprising Fe 2 O 3 , and said first effect pigment has a color angle of about 10 to about 25;
wherein the second effect pigment consists of a substrate and one or more colorless metal oxide layers, and said second effect pigment has a color angle of about 260 to about 310; and
wherein said UV-stable composition has a color angle of about 340 to about 360, a color chroma of at least about 50, is not subject to UV-light instability, and does not comprise carmine.
2. The composition of claim 1 , wherein the first effect pigment and the second effect pigment are present in the composition in a ratio of about 2:1 to about 5:1 by weight.
3. The composition of claim 1 , wherein the first effect pigment is present in the composition at about 65% to about 85% by weight.
4. The composition of claim 1 , wherein the second effect pigment is present in the composition at about 15% to about 35% by weight.
5. The composition of claim 1 , wherein said substrate of said first effect pigment is mica and said substrate has a single layer of Fe 2 O 3 .
6. The composition of claim 1 , wherein said substrate of said first effect pigment is mica and said substrate comprises at least one layer of Fe 2 O 3 , at least one layer of silicon dioxide (SiO 2 ) and at least one layer of titanium dioxide (TiO 2 .
7. The composition of claim 1 , wherein said substrate of said second effect pigment is mica and said second effect pigment comprises a layer of rutile titanium. dioxide.
8. The composition of claim 1 , wherein said first effect pigment is selected from the group consisting of: substrate/TiO 2 /SiO 2 /Fe 2 O 3 /SiO 2 /TiO 2 ; substrate/Fe 2 O 3 /SiO 2 /Fe 2 O 3 /SiO 2 /TiO 2 ; substrate/SiO 2 /Fe 2 O 3 ; substrate/TiO 2 /SiO 2 /Fe 2 O 3 ; substrate/Fe 2 O 3 /SiO 2 ; substrate/Fe 2 O 3 /SiO 2 /Fe 2 O 3 ; substrate/Fe 2 O 3 /SiO 2 /TiO 2 ; substrate/Fe 2 O 3 /SiO 2 /TiO 2 /SiO 2 /TiO 2 ; and substrate/TiO 2 /SiO 2 /TiO 2 /SiO 2 /Fe 2 O 3 .
9. A cosmetic composition comprising the composition of claim 1 and optionally at least one cosmetically-acceptable auxiliary agent.
10. A UV-stable composition comprising: a first effect pigment and a second effect pigment,
wherein the first effect pigment comprises a substrate and at least one layer comprising Fe 2 O 3 , and said first effect pigment has a color angle of about 10 to about 25;
wherein the second effect pigment consists of a substrate and one or more colorless metal oxide layers, and said second effect pigment has a color angle of about 260 to about 310; and
wherein said UV-stable composition has a color of an angle of about 340 to about 360, a color chroma of at least 50, and does not comprise carmine, and
wherein the color angle and chroma of the UV-stable composition are not changed by UV irradiation.
