Description

Anti-migration cosmetic composition comprising block polymer

The present invention relates to cosmetic compositions comprising specific block polymers to be applied to human keratinous substances such as skin, lips, eyelashes, eyebrows, nails and hair. The composition will more particularly be applied to the skin or lips.

The compositions according to the invention may be cosmetic or care compositions for keratinous substances, in particular for the skin and lips, and are preferably cosmetic compositions.

The cosmetic composition may be a lip makeup product (lipstick), foundation, eye shadow, makeup blush, concealer product, eyeliner, body makeup product, mascara, nail polish or hair makeup product.

The care composition may be a body and face skin care product, in particular a sun protection product or a skin coloring product (such as a self-tanning product). The composition may also be a hair care product, in particular a hair holding or hair shaping product.

Lipstick and foundation compositions are commonly used to impart aesthetically pleasing color to the lips or skin, and especially the face. These cosmetic products generally contain an aliphatic phase, such as waxes and oils, pigments and/or fillers and optional additives, such as cosmetic or dermatological active agents.

When applied to the skin, these compositions have the disadvantage of migrating, ie depositing at least in part, and leaving marks on some support with which they come into contact, in particular glass, cups, cigarettes, fabrics or skin. This leads to poor persistence of the applied film, and the foundation or lipstick composition must be reapplied from time to time. Furthermore, the appearance of these unacceptable marks, especially on collars, can make some women resent the use of this type of cosmetics.

Therefore, "migration-resistant" lip and skin cosmetic compositions are sought, which have the advantage of forming deposits that are at least partially non-depositing on the support (glass, clothing, cigarette or fabric) with which they come into contact.

In order to limit the migration of cosmetic compositions, it is known practice to use volatile oils, especially in amounts greater than 40% by weight. The high presence of these volatile oils in cosmetic products, especially in lipsticks, causes discomfort for the user: makeup deposits give a feeling of dryness and tightness.

There are also products in the form of two separate compositions applied on the lips, one covering the other to obtain an anti-migration makeup effect. For example, Max Factor's Lip Finity product is a two-coat product whose base composition (called the base coat) contains silicone and volatile oils, and whose surface composition (called the top coat) contains sucrose ester ( as described in patent application WO 97/17057) to improve the comfort of anti-migration cosmetic products. However, the need to apply two compositions for facial makeup may be unacceptable to some users.

The object of the present invention is to provide a new formulation of cosmetic compositions, in particular cosmetic compositions, which make it possible to obtain deposits with good anti-migration properties, in particular without the use of large quantities of volatile oils, which deposits can Obtained only with this composition.

It is also an object of the present invention to provide a cosmetic composition, in particular a cosmetic composition, which makes it possible to obtain a comfortable deposit on the skin or on the lips.

The inventors have found that such compositions can be obtained with specific block polymers described hereinafter. Said composition makes it possible to obtain deposits with good anti-migration properties, in particular to obtain a cosmetic effect on keratinous substances, especially on the skin or lips. Furthermore, the deposit obtained on the skin or lips does not give the user any feeling of dryness or tightness: the deposit is therefore pleasant.

More specifically, therefore, a subject of the present invention is a cosmetic composition comprising at least one cosmetically acceptable organic liquid medium and at least one film-forming linear block olefin polymer as described below, said composition being in particular as defined below.

According to a first embodiment of the composition of the present invention, the film-forming linear block olefin polymer is preferably free of styrene and is a polymer that, when present in said composition in sufficient amount, said combination substances capable of forming sediments with migration less than or equal to 35%.

According to a second embodiment of the composition of the present invention, the film-forming linear block olefinic polymer is preferably non-elastomeric and is such a polymer that, when present in said composition in sufficient amount, said combination substances capable of forming sediments with migration less than or equal to 35%.

Compositions according to the invention are preferably capable of forming deposits with a migration of less than or equal to 35%, preferably less than or equal to 30%, more preferably less than or equal to 25%, still more preferably less than or equal to 20%, more particularly preferably less than or equal to 15%. , still more particularly preferably less than or equal to 10% and most preferably less than or equal to 5%.

A subject of the present invention is also a non-therapeutic cosmetic or caring cosmetic method for keratinous substances, especially the skin or lips, which method comprises applying a composition as defined above to keratinous substances, in particular to the skin or on the lips.

A subject of the present invention is also the use of a composition as defined above to obtain an anti-migration deposit, in particular an anti-migration cosmetic effect, on keratinous substances, in particular on the skin or lips.

A subject of the present invention is also a block polymer as defined above in a cosmetic composition comprising a cosmetically acceptable organic liquid medium to obtain resistance to migratory deposits on keratinous substances, in particular on the skin or lips, in particular against Use to transfer makeup effects.

The migration of the compositions of the present invention to obtain deposits was determined as follows.

An adhesive polyethylene foam support (40mm×70mm rectangle, 3mm thick) with a density of 33Kg/m ³ (sold under the name RE40×70EP3 by Joint Technique Lyonnais Ind) was placed on a hot plate maintained at 40°C Preheating on the computer, so that the surface temperature of the support is maintained at 33°C ± 1°C.

The composition was applied to the entire non-stick surface of the support by spreading with a fine brush to obtain a composition deposit of about 15 μm while the support was placed on a hot plate and then left to dry for 30 minutes.

After drying, the support is glued by its adhesive side to an anvil with a diameter of 20 mm and fitted with a thread pitch. The support/deposit combination was then cut with an 18mm diameter punch. The anvil was then spun onto a printing press (Statif Manuel Imada SV-2 from Someco) equipped with an extensible testing apparatus (Imada DPS-20 from Someco).

80 g/ ^m2 white photocopy paper was placed on the press plate and the support/deposit combination was pressed against the paper with a pressure of 2.5 Kg for 30 seconds. After removing the support/sediment combination, some of the sediment transferred to the paper. Then use a Minolta CR300 colorimeter to measure the color of the sediment transferred to the paper, and use the chromaticity parameters L ^★ , a ^★ , b ^★ to characterize the color. Measure the chromaticity parameters L ^★ ₀ , a ^★ ₀ and b ^★ ₀ of the color of the plain paper used.

Then, the color difference ΔE1 of the color of the transferred deposit relative to the color of plain paper is determined by the following formula:

$\mathrm{<span\; class="notranslate">\; \&Delta;E</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; =</span>\sqrt{{<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; L</span>}}^{<span\; class="notranslate">\; *</span>}<span\; class="notranslate">\; -</span>{{\mathrm{<span\; class="notranslate">\; L</span>}}_{\mathrm{<span\; class="notranslate">\; 0</span>}}}^{<span\; class="notranslate">\; *</span>}<span\; class="notranslate">\; )</span>}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; +</span>{<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; a</span>}}^{<span\; class="notranslate">\; *</span>}<span\; class="notranslate">\; -</span>{{\mathrm{<span\; class="notranslate">\; a</span>}}_{\mathrm{<span\; class="notranslate">\; 0</span>}}}^{<span\; class="notranslate">\; *</span>}<span\; class="notranslate">\; )</span>}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; +</span>{<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; b</span>}}^{<span\; class="notranslate">\; *</span>}<span\; class="notranslate">\; -</span>{{\mathrm{<span\; class="notranslate">\; b</span>}}_{\mathrm{<span\; class="notranslate">\; 0</span>}}}^{<span\; class="notranslate">\; *</span>}<span\; class="notranslate">\; )</span>}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}$

In addition, a total migration standard was prepared by applying the composition directly on the same paper as used above: at room temperature (25° C.), the composition was applied with a fine brush to obtain a deposit of about 15 μm of the composition, and the deposit was then allowed to Leave to dry at room temperature (25°C) for 30 minutes. After drying, the colorimetric parameters L ^★' , a ^★' and b ^★' of the color of the deposit placed on paper are measured directly against the total migration standard color. Measure the chromaticity parameters L ^★′ ₀ , a ^★′ 0 and b ^★′ ₀ of the color of the plain paper used.

Then use the following formula to determine the color difference ΔE2 of the total migration standard color relative to the color of plain paper:

$\mathrm{<span\; class="notranslate">\; \&Delta;E</span>}\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; =</span>\sqrt{{<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; L</span>}}^{<span\; class="notranslate">\; *</span><span\; class="notranslate">\; \&prime;</span>}<span\; class="notranslate">\; -</span>{{\mathrm{<span\; class="notranslate">\; L</span>}}_{\mathrm{<span\; class="notranslate">\; 0</span>}}}^{<span\; class="notranslate">\; *</span><span\; class="notranslate">\; \&prime;</span>}<span\; class="notranslate">\; )</span>}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; +</span>{<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; a</span>}}^{<span\; class="notranslate">\; *</span><span\; class="notranslate">\; \&prime;</span>}<span\; class="notranslate">\; -</span>{{\mathrm{<span\; class="notranslate">\; a</span>}}_{\mathrm{<span\; class="notranslate">\; 0</span>}}}^{<span\; class="notranslate">\; *</span><span\; class="notranslate">\; \&prime;</span>}<span\; class="notranslate">\; )</span>}^{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; +</span>{<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; b</span>}}^{<span\; class="notranslate">\; *</span><span\; class="notranslate">\; \&prime;</span>}<span\; class="notranslate">\; -</span>{{\mathrm{<span\; class="notranslate">\; b</span>}}_{\mathrm{<span\; class="notranslate">\; 0</span>}}}^{<span\; class="notranslate">\; *</span><span\; class="notranslate">\; \&prime;</span>}<span\; class="notranslate">\; )</span>}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}$

Composition migration expressed as a percentage is equal to the following ratio:

                                                          

Measurements are carried out consecutively on 4 supports, the migration value corresponds to the mean of four measurements on 4 supports.

The term "olefinic polymer" refers to a polymer obtained by polymerizing monomers containing ethylenic unsaturated bonds.

The term "block polymer" refers to a polymer comprising at least two different blocks and preferably at least three different blocks.

The polymer is a linear polymer. In contrast, non-linear structure polymers are, for example, polymers of branched structure, starburst or grafted form or similar structures.

The term "film-forming polymer" refers to a polymer capable of forming a continuous film by itself or in the presence of film-forming aids, said film being attached to a support and in particular a keratinous substance.

Preferably the polymer backbone used in the composition of the invention does not contain silicon atoms. The term "backbone" refers to the main chain of a polymer, as opposed to side chains.

The block polymer preferably comprises at least one first block and at least one second block, the two blocks having different glass transition temperatures (Tg), so The first block and the second block are linked together by an intermediate block comprising at least one monomer constituting the first block and at least one monomer constituting the second block.

The term "at least one block" refers to one or more blocks.

It should be noted that the terms "first block" and "second block" in this context do not in any way determine the order of said blocks in the polymer structure.

Preferably the first and second blocks in the block polymer are mutually incompatible.

The term "mutually incompatible block" means that the mixture formed by the polymer corresponding to the first block and the polymer corresponding to the second block is immiscible in the organic liquid, at room temperature (25 ° C) and normal pressure (10 ⁵ Pa), when the content of the polymer mixture is greater than or equal to 5% by weight relative to the total weight of the mixture (polymer and solvent), the organic liquid accounts for the weight of the organic liquid medium of the composition Mostly understandable:

i) said polymer is present in the mixture in an amount by weight within the range of 10/90 to 90/10, respectively, and

ii) The polymers corresponding to the first block and the second block each have an average (weight average or number average) molecular mass equal to the average molecular mass of the block polymer ± 15%.

When the organic liquid medium contains an organic liquid mixture, and two or more organic liquids should exist in the same mass ratio, the polymer mixture is immiscible in at least one of them.

Of course, where the organic liquid medium contains only one organic liquid, this liquid is the predominant organic liquid.

The principal organic liquid of the composition is preferably the principal organic solvent of the organic solvent used for the polymerization of the block polymer or of the mixture of organic solvents used for the polymerization of the block polymer.

The block polymer used in the composition of the present invention is preferably water-insoluble, that is, the polymer is insoluble in water or insoluble at room temperature (25° C.) without adjusting the pH, having an active substance content of at least 1% by weight, and at room temperature (25° C.). In a mixture of water and a linear or branched lower monohydric alcohol containing 2 to 5 carbon atoms (such as ethanol, isopropanol or n-propanol).

The block polymers used in the compositions of the present invention are preferably not elastomeric.

The term "non-elastomeric polymer" refers to a polymer that does not return to a length substantially consistent with its original length after forced stretching (eg, relative to 30% of its original length) ceases.

More specifically, the term "non-elastomeric polymer" means a polymer having an instantaneous recovery R _i < 50% and a delayed recovery R _2h < 70% after being elongated by 30%. Preferably R _i < 30% and R _2h < 50%.

More specifically, the inelastic properties of the polymers were determined according to the following procedure:

The polymer solution was poured into a polytetrafluoroethylene-coated mold to prepare a polymer film, which was then dried for 7 days under ambient conditions of 23 ± 5 °C and a relative humidity of 50 ± 10%.

A film about 100 [mu]m thick is thus obtained, which is cut into rectangular samples 15 mm wide and 80 mm long (for example with a punch).

The samples were tested for tensile stress under the same conditions of temperature and humidity as for drying, using a machine sold by Zwick.

The sample is pulled at a speed of 50 mm/min with a distance between the jaws of 50 mm, which corresponds to the original length of the sample (l ₀ ).

The instantaneous recovery rate R _i is determined by the following method:

- elongate the sample by 30% (ε _max ), i.e. about 0.3 times its original length (l ₀ )

- Measure the percentage of elongation remaining after the sample returns to zero restraint (ε _i ) by releasing the restraint with a return speed equal to the stretching speed, ie 50 mm/min.

The percentage of instantaneous restoration (R _i ) is given by the following formula:

R _i ＝(ε _max -ε _i )/ε _max )×100

The percentage of remaining elongated portion (ε _2h ) of the sample was measured to determine the delayed recovery rate.

The percentage of delayed recovery (R _2h ) is given by the following formula:

R _2h ＝(ε _max -ε _2h )/ε _maxx )×100

As a guide only, the polymer in one embodiment of the invention has an instantaneous recovery R _i of 10% and a delayed recovery R _2h of 30%.

This means that the individual blocks can consist of homopolymers or copolymers; such copolymers can form the blocks randomly or alternately in succession.

The midblock of the polymer comprising at least one first block constituent monomer and at least one second block constituent monomer is preferably a random polymer.

It is preferred that the middle block is substantially derived from the constituent monomers of the first block and the second block.

The term "substantially" means at least 85%, preferably at least 90%, better 95% and most preferably 100%.

The glass transition temperature Tg of the middle block is preferably between the glass transition temperatures of the first block and the second block.

The glass transition temperature indicating the first block and the second block may be a theoretical Tg value determined from the theoretical Tg values of the constituent monomers of each block, which can be found in reference manuals, such as Polymer Handbook, p. Third Edition, 1989, John Wiley, according to the following relationship, also known as Fox's rule:

为所考虑嵌段中单体i的质量部分，Tg_i为单体i均聚物的玻璃化转变温度。

is the mass fraction of monomer i in the considered block, and _Tgi is the glass transition temperature of the homopolymer of monomer i.
