DESCRIPTION
Composition to be applied on the skin, lips and / or appendages
[0001] The present invention relates to cosmetic compositions to be applied to the skin, including the mucous membranes, particularly the lips, and the appendages, particularly the nails, eyelashes, eyebrows and hair.
[0002] Organic coloring matters are normally used to add color to cosmetic compositions.
However, conventional organic coloring matters do not make it possible to obtain compositions exhibiting satisfactory hiding power.
Furthermore, the shades contributed by these organic coloring matters vary strongly between the dry state and the state in dispersion in a cosmetic solvent.
[0003] There is a need for cosmetic compositions exhibiting a satisfactory C * saturation and a sufficiently high covering power.
[0004] There is also a need for pigments that have a weak color change depending on the surrounding environment.
[0005] The present invention relates to meeting all or part of the needs mentioned above.
[0006] This is achieved thanks to a composition that has an advantageously hiding power between approximately 25 and approximately 100, for example between approximately 25 and approximately 90, even between approximately 30 and approximately 100, for example between approximately 30 and approximately 90, this composition being intended to be applied to the skin, lips and / or appendages and including the particles of at least one compound pigment, these particles comprising:
• an inorganic core, • at least one at least partial coating of at least one organic coloring matter in an amount sufficient so that the C * saturation of the composition is preferably between about 25 and about 100, even between about 30 and about 100 .
[0007] Thanks to the invention, it is possible to obtain both saturated and covering compositions.
[0008] The content of composite pigment in the composition can be comprised between about 0.1% and about 30%, even between about 0.1% and about 20%, for example between about 0.1% and about 15%, even between approximately 0.3% and approximately 10%, for example between approximately 1% and approximately 5% by weight, relative to the total weight of the composition.
[0009] In particular, a relatively high composite pigment content can be chosen to obtain the desired hiding power and in particular a relatively high hiding power.
[0010] A suitable shade can be obtained in various ways, for example by mixing compound pigments according to the invention, these pigments having different colors and / or by the presence of various organic coloring matters in the coating of the cores of the or of compound pigments, these organic coloring matters being for example mixed or present in respective layers of the coating.
[0011] By "an at least partial coating", in the sense of the present invention is meant a coating of all or part of the inorganic core.
[0012] The composition according to the invention may contain a physiologically acceptable medium.
[0013] By "physiologically acceptable medium" is meant a medium that is non-toxic and capable of being applied to the skin, lips or appendages of human beings, particularly a cosmetic medium.
The physiologically acceptable medium will be adapted to the nature of the support on which the composition is to be applied, and to the form in which the composition is intended to be conditioned, particularly solid or fluid at room temperature and under atmospheric pressure.
[0014] By "cosmetic composition", a composition is designated as defined in the directive 93/35 / EEC of the council of June 14, 1993.
MEASURING SATURATION C *
[0015] In the case of a liquid or pasty composition, a sample of the composition to be studied is introduced into a metal container approximately 1 cm deep.
ES 2 575 512 T3
A 1 mm thick sheet of quartz is applied to the composition, taking care to avoid air bubbles before making the measurement.
[0016] In the case of a powder composition, the powder sample is compacted at a pressure of 10 MPa in a metal container approximately 1 cm deep.
A 1 mm thick sheet of quartz is applied to the composition before taking the measurement.
[0017] In the case of a stick, the composition is cast in a flat-bottomed quartz mold approximately 2 cm deep.
[0018] The trichromatic coordinates L *, a *, b * of the composition in the CIE L * a * b * space are measured using a MINOLTA CM-508d spectrocolorimeter, under illuminant D65, with a specular component included and a d / 8 lighting system.
[0019] The saturation C * of the composition is calculated using the formula C * = [(a *)<sup>2</sup>+ (b *)<sup>2</sup>]<sup>1/2</sup>
COVERING POWER MEASUREMENT
[0020] In the case of a stick, the formulation is previously kneaded so as to obtain a viscous paste.
In the case of a powder, 50 parts by weight of the powder are kneaded with 50 parts by weight of dimethicone (DC 200 Fluid 5CST from DOW CORNING) so that a viscous paste is obtained.
The formulation is then spread with a thickness of 30 pm on an Erichsen contrast card, type 24/5, presenting a black background and a white background, and the trichromatic coordinates (X, Y, Z) are measured with help of a CR-300 colorimeter.
Similar expansions are made on two other contrast cards and three measurements are made on each card.
The mean corresponding to these nine measurements is then calculated.
[0024] The covering power is equal to 100 x Yn / Yb where Yn is the mean value of Y on a black background and Yb is the mean value of Y on a white background.
A covering power of 100 corresponds to a completely opaque formulation.
COMPOSITE PIGMENT
Structure
[0025] A composite pigment according to the invention can be composed in particular of particles comprising:
• an inorganic core, • at least one at least partial coating of at least one organic coloring matter.
[0026] At least one binder can advantageously contribute to the fixation of the organic coloring matter on the inorganic core.
[0027] The composite pigment particles can have various shapes.
These particles can be particularly plate-shaped or globular, in particular spherical, and be hollow or filled.
By "plate-shaped", we mean particles whose ratio of greatest dimension to thickness is greater than or equal to 5.
[0028] A compound pigment according to the invention can have, for example, a specific surface area between 1 and 1000 μm<sup>2</sup>/ g, particularly between 10 and 600 m<sup>2</sup>/ g approximately, and in particular between 20 and 400 m<sup>2</sup>/ g approximately.
The specific surface is the value measured by the BET method.
The mass proportion of the core can exceed 50% with respect to the total weight of the composite pigment, for example going from 50% to 70%, for example from 60% to 70%.
[0030] The composition may contain only one or more compound pigments as defined above or alternatively contain one or more compound pigments as well as pigments having a non-compound structure, particularly mineral, interference pigments, lacquers or organic pigments.
The composition can in particular be devoid of uncoated TiO2 particles.
ES 2 575 512 T3
The composite pigment can be different from an interference pigment as described for example in US Pat. No. 6,428,773.
An interference pigment includes, for example, several layers of constant thickness of materials selected to be able to produce the optical interferences.
[0032] The C * saturation of the composite pigment is greater than or equal to 30, measured according to the protocol below.
Composite pigment saturation measurement protocol:
[0033] The a * and b * values in the CIE L * a * b * space of the composite pigment are measured as follows:
The pure composite pigment is compacted in a rectangular container having dimensions 2 x 1.5 cm and a depth of 3 mm, applying a pressure of 100 bar.
[0035] The a * and b * values of the compacted pigment are measured with a MINOLTA 3700d spectrophotometer, in specular mode excluded, under illuminant D65 medium aperture.
Saturation is given by C * = (a *<sup>2</sup> + b *<sup>2</sup>)<sup>12</sup>
Inorganic core
The inorganic core can be in any way suitable for fixing particles of organic coloring matter, for example spherical, globular, granular, polyhedral, acicular, fusiform, flattened in the shape of a flake, rice grain, flake, as well as a combination of these forms, this list is not limiting.
Preferably, the ratio of the largest dimension of the core to its smallest dimension is between 1 and 50.
The inorganic core can have a mean size between approximately 1 nm and approximately 100 nm, even between approximately 5 nm and approximately 75 nm, for example between approximately 10 nm and approximately 50 nm, particularly 20 or 25 nm.
[0039] By "mean size", the dimension given by the statistical granulometric distribution to half of the population is designated, called D50.
The mean size can be a number mean size determined by image analysis (electron microscopy).
The inorganic core can have a refractive index greater than or equal to 2, even greater than or equal to 2.1, for example greater than or equal to 2.2.
The inorganic core includes the oxides of titanium
Titanium oxides, particularly TiO2, are particularly suitable.
[0043] The inorganic core can have a specific surface area, measured by the BET method, comprised for example between approximately 1 m<sup>2</sup>/ g and about 1000 m<sup>2</sup>/ g, better between about 10 m<sup>2</sup>/ g and about 600 m<sup>2</sup>/ g, for example between approximately 20 m<sup>2</sup>/ g and about 400 m<sup>2</sup>/ g.
The inorganic core can be colored, if applicable.
Organic coloring matter
The organic coloring matter can contain, for example, at least one organic pigment, for example at least one organic lacquer.
The organic coloring matter can be chosen, for example, from particulate compounds insoluble in the physiologically acceptable medium of the composition.
The organic coloring matter can contain, for example, pigments, for example organic lacquers or other organic coloring matters, which can be chosen from the compounds below and their mixtures:
• cochineal carmine, • organic pigments of azo, anthraquinone, indigos, xanthenic, pyrene, quinoline, triphenylmethane, fluoran dyes, • organic lakes or insoluble salts of sodium, potassium, calcium, barium, aluminum, zirconium, strontium, titanium, acid dyes such as azo, anthraquinone, indigo, xanthenic, pyrene, quinoline, triphenylmethane, fluorane dyes, these colorants can contain at least one carboxylic or sulfonic acid group.

[0071] In order to obtain a layer that covers the inorganic cores uniformly, the binder is preferably in a liquid state or soluble in water or in different solvents.
The amount of binder can vary from 0.01 to 15%, particularly from 0.02 to 12.5% and in particular from 0.03 to 10% by weight (calculated with respect to C or Si) with respect to the weight of the particles comprising the core and the binder. For more details on how to calculate the relative amount of the binder, reference may be made to application EP 1 184 426 A2.
The relative proportion of binder can be less than or equal to 5%, for example less than or equal to 3%, with respect to the total weight of the composite pigment.
Compound Pigment Preparation
[0073] The composite pigment can be prepared by any appropriate method, for example a mechanochemical process or a solution precipitation process, with dissolution of the organic coloring matter and then precipitation on the surface of the core.
[0074] A binder may or may not be used.
[0075] A process comprising a mechanical mixture of an organic pigment and the inorganic core is preferred.
[0076] A binder can be added and mixed with the inorganic core before the introduction of the organic coloring matter.
[0077] The compound pigment can be produced, for example, by one of the procedures described in European patent applications EP 1 184 426 and Ep 1 217 046, the contents of which are incorporated herein by reference, advantageously by the procedure described in application Ep 1 184 426.
[0078] In an exemplary embodiment, one begins by mixing the particles destined to constitute the inorganic core with the binder
[0079] In order for the binder to adhere uniformly to the surface of the inorganic core, it is preferable to pass these particles previously in a grinder, so that they deagglomerate.
[0080] The mixing and stirring conditions are selected in such a way that the core is uniformly coated with binder.
These conditions can be controlled so that the linear load is comprised between 19.6 and 19160 N / cm, in particular between 98 and 14170 N / cm and better between 147 and 980 N / cm; the treatment time is particularly between 5 min and 24 hours and better from 10 min to 20 hours; the speed of rotation can be comprised between 2 and 1000 trs / min, in particular between 5 and 1000 trs / min and better between 10 and 800 trs / min.
[0081] After the binder has coated the inorganic core, the organic coloring matter is added and mixed with stirring to adhere to the binder layer.
[0082] The methods of addition can be for example a bulk, continuous, or small amount addition.
[0083] Mixing and agitation, either of the inorganic cores with the binder or of the organic coloring matter with the binder-coated inorganic cores, can be accomplished using an apparatus that can apply spatular and / or compression shear force to the powder mix.
Such equipment is, for example, wheel mixers, sheet mixers and the like.
Wheel mixers are particularly suitable. A list of suitable apparatus is given in application EP 1 184 426 A2.
[0084] Another method of manufacturing a composite pigment is described in JP 3286463, which discloses a solution precipitation process.
ES 2 575 512 T3
The organic coloring matter is dissolved in ethanol, the inorganic nuclei are then dispersed in this ethanolic solution.
[0086] Next, an alkaline aqueous solution of sodium or potassium carbonate is slowly added to these mixtures, then finally, slowly, an ethanolic solution of calcium chloride, all under stirring.
