#CMT# #/CMT# Making-up dark skin involves applying to the skin a cosmetic composition (C1) comprising at least one red interference pigment in a medium, in which when the composition is applied to the skin, it generates highlights with an intensity of >= 3000 cd.m -> 2> and a dominant wavelength of 580-650 nm. #CMT# : #/CMT# Independent claims are included for the following: (1) a makeup composition (C2) comprising at least one colorant, and at least one red interference pigment in a medium, where when the composition is applied to the skin, it generates highlights with an intensity of >= 3000 cd.m -> 2> and a dominant wavelength of 580-650 nm; and (2) a set of at least two cosmetic compositions (C1), where the saturation difference between two compositions of the set is = 2, the red interference pigment in the two compositions is at concentrations that differ by at least 1%. #CMT#USE : #/CMT# For making-up dark skin (claimed) including black and colored skin. #CMT#ADVANTAGE : #/CMT# The composition generates highlights with high intensity and specific dominant wavelength. The composition presents specific turbidity index; this allows the color produced by the interference phenomenon is clearly dominating compared to the color produced by adsorption for precise conditions of observation. The composition exploits the very particular sensitivity of the red interference pigment to its environment. #CMT#INORGANIC CHEMISTRY : #/CMT# Preferred Components: The size of the red interference pigment is >= 30 (preferably >= 40, especially 30-80) mu m. The red interference pigment includes an inorganic core that is made of silica, glass, or mica. The method includes a surface layer of a metal oxide (preferably iron oxide (Fe 2O 3)). The interference pigment generates highlights with an intensity of >= 3400 cdm -> 2>. #CMT#ORGANIC CHEMISTRY : #/CMT# The colorant is hydrosoluble or liposoluble; and selected from amongst caramel, beetroot juice and carmine, betanin (beetroot), copper chlorophyllin, methylene blue, anthocyanins (enocianin, black carrot, hibiscus, elder), riboflavin, Sudan red, beta -carotene, carotenoids, lycopene, palm oil, Sudan brown, quinoline yellow and xanthophylles (capsanthin, capsorubin, lutein), curcumin, anthocyans from flowers or fruit and their derivatives, flavonoids and tannins extracted from native or fermented vegetables, juglone, lawsone, fermented soya extracts, algae, fungi, micro-organisms, Flavylium salts not substituted in the 3-position, extracts from Gesneria fulgens, Blechum procerum, Saxifraga and pigments which can be obtained by extraction with an organic or hydro-organic solvent from a culture medium of micromycetes of the monascus Monascus type, synthetic liposoluble colorants such as DC Red 17, DC Red 21, DC Red 27, DC Green 6, DC Yellow 11, DC Violet 2, and DC Orange 5, and synthetic hydrosoluble colorants such as FDC Red 4, DC Red 6, DC Red 22, DC Red 28, DC Red 30, DC Red 33, DC Orange 4, DC Yellow 5, DC Yellow 6, DC Yellow 8, FDC Green 3, DC Green 5, and FDC Blue 1. #CMT#PHARMACEUTICALS : #/CMT# Preferred Composition: The composition (C1) presenting saturation C* that is >= 30 (preferably >= 35), and a hue angle of 10-30 (preferably 15-25)[deg]. The amount of red interference pigment is 0.1-15 wt.% when the composition (C1) is liquid, and is 0.1-60 wt.% when the composition (C1) is solid. The composition (C1) has no coloring agent other than the red interferential pigment. The composition (C1) comprises a colorant. The red interference pigment creates highlights with an intensity of >= 3500 cd.m -> 2>, where the composition (C2) not containing, in the medium, white fillers or solid bodies that generate a color by absorption, or when the composition (C2) does contains them, the total amount of such solid bodies is = 1 wt.% relative to the total weight of the composition (C2). The composition (C2) comprises reflective particles that generates, on the surface, other highlights with an intensity that is >= to the intensity of the red interference pigment. The composition (C2) presents a turbidity index of = 100 nephlometric turbidity units (NTU), and comprises magnetic bodies presenting non-zero magnetic susceptibility. The composition (C2) comprises a reflective second pigment that is silvery or that is colored with a dominant wavelength such that the absolute value of difference between dominant wavelength of first pigment and dominant wavelength of second pigment is >= 50 nm, this second pigment has an average size that is >= 30 (preferably 40) mu m. The composition (C2) comprises at least one coloring agent that is sensitive to at least one external stimulus. #CMT#EXAMPLE : #/CMT# A composition in the form of blusher, comprising (wt.%): magnesium (1.5), sodium carboxymethyl cellulose (0.5), distearyl dimethyl ammonium modified hectorite (1), cyclopenia dimethylsiloxane (16), glycerol (5), oxyethylene polymethylcetyl dimethyl methylsiloxane/polyglycerol-4 isostearate/hexyl laurate mixture (9), water (41.6), acetyl ethylene glycol stearate/glyceryl tri-stearate mixture (0.3), poly dimethylsiloxane (with viscosity of 5 cSt) (16), XIRONA LE ROUGE (RTM: red interference pigment with silica core covered with a layer of iron oxide) (5) and 1,5-pentanediol (3), was prepared. |
