Abstract: The invention relates to a process for the manufacture of a colored make-up cosmetic composition which makes it possible to produce a transparent or translucent colored coat on the skin, lips or superficial body growths, comprising the following successive steps: (1) selecting a cosmetically acceptable base having bulk opaqueness, translucency or transparency, (2) preparing at least one series of samples of this cosmetic base, each series comprising increasing amounts of a coloring agent dissolved or dispersed in the cosmetically acceptable base, (3) spreading each of the samples of the one or more series over a transparent slide having a recess with a depth of 10 ?m, (4) measuring, for each of the samples of the one or more series, the transmission of the layer thus formed at the wavelength corresponding to the maximum of one of the absorption or scattering peaks (?max) of the coloring agent, (5) drawing a calibration curve by plotting the values of the transmission at ?max as a function of the concentratio

Abstract: The present invention relates to a composition of foundation type, especially for making up the skin, in particular dark skins, comprising, in a physiologically acceptable medium, at least one colouring agent and reflective particles, the said composition having a hue in the colour range extending from pink-beige to orange-brown.

Abstract: The present invention relates to an interference pigment having a multilayer structure, characterized in that it has a spectral reflectance that differs by not more than 20% from a reference spectral reflectance, preferably of a type of keratin material, for at least a portion of the visible spectrum 200 nm broad, this pigment being characterized in that the multilayer structure comprises at least one layer substantially totally coating an underlying layer.

Abstract: Goniochromatic/light reflecting cosmetic compositions well suited for making up the skin, lips, hair or integuments, contain (a) at least one goniochromatic coloring agent suited for creating a goniochromatic colored background and (b) an amount of light reflective particles suited for creating highlight points that are visible to the naked eye, formulated into (c) a topically applicable, physiologically acceptable medium therefor.

Abstract: The present invention relates to a cosmetic Product containing at least a first composition and a second composition, the first composition containing at least one first dye in a first physiologically acceptable medium, and the second composition containing at least one second dye in a second physiologically acceptable medium, the first dye being photochromic and the second dye being at least one goniochromatic coloring agent.

Abstract: The present invention relates to a cosmetic composition, especially for making up the skin, the lips and/or the integuments, combining at least two dyes, including at least one photochromic dye.

Abstract: The present invention relates to the use of an &agr;,&ohgr;-substituted oxyalkylenated silicone, in particular of formula (I) below: 1

Abstract: The invention relates to the use of a cosmetic composition with a hydrophilic continuous phase comprising a goniochromatic pigment with an interferential multilayer structure as make-up.

Abstract: The subject of the invention is a composition comprising, in a physiologically acceptable medium, interferential particles exhibiting a colour effect and an additional colouring agent, the said colouring agent being present in a sufficient quantity not to mask the colour effect of the said interferential particles.

Abstract: The invention concerns a method which includes the steps of: introducing into a pre-drilled portion of a well (16) a drilling system containing a drilling bit (11) assembled with tubular lining elements (15), an element for measuring the inclination and azimuth direction of the pre-drilled part of the well, an element for rotary friction (26, 27) against the wall of the pre-drilled part and an element capable of modifying the friction coefficient of the friction element against the wall; measuring the azimuth direction of the pre-drilled part of the well (16); and varying the friction coefficient of the friction element (26, 27) sufficiently to influence the azimuth direction of the next well portion to be drilled.

Abstract: The present invention relates to a new makeup kit comprising a first, goniochromatic pigment composition which is intended to form a base layer and a second, conventional pigment composition having one of the colors of the first pigment, the second composition being intended to form a surface layer comprising decorative motifs. Depending on the viewing angle, therefore, it is possible to see the said motifs appear or disappear. This kit is intended in particular for making up the nails, lips, cheeks or eyelids, or else the body. The invention also relates to a method of making up the human face, lips or body.

Abstract: The invention concerns a self-penetrating drilling method and a thrust-generating tool: the tool (1) comprises N blades (2a, 2b, 2c, 2d). Each blade comprised K drill bits (3a, 3b, 3c, 3d). The shapes, positions and orientations of said drill bits are determined in the following manner: the kth drill bit of the last blade drills, at the (q−1)th of the tool rotational cycle, a cut in the rock downstream of the one produced by the (k+1)th drill bit of the first blade at the qth rotational cycle of the tool; the kth drill bit of the nth blade drills, at the q?th rotational cycle of the tool, a cut in the rock downstream of the one produced by the kth drill bit of the (n+1)th blade at the qth rotational cycle of the tool; the normal to the leading edge of the drill bit has a component along the axis of rotation oriented towards upstream.
