Make-up composition producing a change in colour on application

摘要

The invention relates to a cosmetic composition for making up the skin, lips or superficial body growths, comprising
a cosmetic base,at least one colored inorganic pigment [A] in an amount sufficient to define a first color of said composition in its body, andat least one pigment [B] chosen from organic dye lakes, the color of which is different from that of the pigment [A], in an amount sufficient to define a second color, radically different from said first color, which is revealed after the application of said composition on the lips, skin or superficial body growths.

主权项

1. A lipstick composition for making up lips, producing a change in color upon application on the lips, comprising:
a lipstick base; 0.3 to 1.5% by weight of black iron oxide as one colored inorganic pigment [A]; and 3 to 10% by weight of at least one colored organic dye lake pigment [B] selected from the group consisting of red, orange, green, yellow, blue lakes and mixtures thereof, wherein the ratio by weight for pigment [B]/pigment [A] in the composition is between 2 and 15, wherein said composition having a thickness of between 5 and 20 mm exhibits a black first color, the composition having a thickness of less than 1 mm exhibits a second color, and the ΔE* colorimetric difference between the first color and the second color is at least 30 units, said ΔE* colorimetric difference being defined by the formula
ΔE*=√{square root over ((L1−L2)2+(a1−a2)2+(b1−b2)2)}in which L1, a1 and b1 are the coordinates in the CIE Lab colorimetric space of the first color and L2, a2 and b2 are those of the second color and
wherein the lipstick composition comprises less than 1% by weight in total of opacifying filler(s) selected from the group consisting of talc; starch, kaolin, zinc and titanium oxides, calcium carbonate, silica, metal soaps derived from organic carboxylic acids, synthetic polymer powders and their mixtures.
