The present disclosure relates to cosmetic compositions with improved properties, intended for cleaning, conditioning and/or styling keratin materials, such as the hair. In one embodiment, the composition comprises, in a cosmetically acceptable support, a washing base comprising at least one surfactant with detergent power, in which particles with a melting point of greater than 70° C. are also present in combination with drawing polymers. The present disclosure also relates to the use of the compositions in the abovementioned cosmetic application.
It is common practice to use detergent hair compositions (or shampoos) based essentially on standard surfactants of anionic, nonionic and/or amphoteric type, such as surfactants of anionic type, to clean and/or wash the hair. These compositions are applied to wet hair and the lather generated by massaging or rubbing with the hands removes, after rinsing with water, the various types of soiling initially present on the hair.
These base compositions may have good washing power, but the intrinsic cosmetic properties associated therewith may nevertheless remain fairly poor, owing, for example, to the fact that the relatively aggressive nature of such a cleaning treatment can, in the long run, lead to more or less pronounced damage to the hair fiber, this damage being associated, for example, with the gradual removal of the lipids or proteins contained in or on the surface of the fiber.
Thus, in order to improve the cosmetic properties of the above detergent compositions, such as those that are intended to be applied to sensitized hair (i.e., hair that has been damaged or made brittle, for example, due to the chemical action of atmospheric agents and/or hair treatments such as permanent-waving, dyeing or bleaching), it is now common practice to introduce additional cosmetic agents known as conditioners into these compositions. These conditioners are generally intended to repair or limit the harmful or undesirable effects induced by the various treatments or aggressions to which the hair fibers are subjected more or less repeatedly. These conditioners may, of course, also improve the cosmetic behavior of natural hair.
The conditioners most commonly used to date in shampoos are cationic polymers, which give washed, dry or wet hair an ease of disentangling, softness and smoothness that may markedly be better than those that may be obtained with corresponding cleaning compositions not containing such conditioners.
Moreover, it has for some time been sought to obtain conditioning shampoos that are capable of giving washed hair not only the cosmetic properties mentioned above but also, to a greater or lesser extent, styling, volume, shaping and hold properties. These washing shampoos with improved general cosmetic properties are often referred to for simplicity as “styling shampoos”, and this term is used in the description hereinbelow.
However, despite the progress made recently in the field of styling shampoos, these shampoos are not really completely satisfactory, and as such there is currently still a strong need for products that can give better performance with respect to one or more of the cosmetic properties mentioned above. For example, it is usually necessary to use a styling product after shampooing, to give the hair a shape and to fix the style.
The present disclosure is directed towards satisfying such a need.
Thus, after considerable research conducted in this matter, the present inventors have now found, entirely surprisingly and unexpectedly, that by combining water-insoluble particles with a melting point of greater than 70° C., as defined below, with certain polymers that have a particular drawing power in detergent compositions, it is possible to substantially and significantly improve the styling and hold properties, while at the same time maintaining their good intrinsic washing power and their cosmetic properties.
For example, these compositions make it possible to obtain very good hold and a certain amount of volume for the hair, for example, a styling effect similar to that obtained with a fixing styling gel used after shampooing. It is moreover found that the keratin fibers are strengthened.
Thus, disclosed herein are novel compositions for washing keratin materials such as the hair, comprising, in a cosmetically acceptable aqueous medium, at least one insoluble particle with a melting point of greater than 70° C., at least one detergent surfactant chosen from anionic, nonionic and amphoteric detergent surfactants and at least one polymer with a drawing power of greater than 5 cm.
Further disclosed herein are methods of cleaning, conditioning, caring for and/or styling keratin materials, such as the hair and the eyelashes, using the disclosed compositions.
Also disclosed herein are cosmetic processes for treating keratin materials, such as keratin fibers, and further such as the hair and the eyelashes, using the composition disclosed herein.
Even further disclosed herein is a shampoo comprising a composition according to the present disclosure.
However, other characteristics, aspects and advantages of the disclosure will emerge even more clearly on reading the description that follows, and also the concrete, but in no way limiting, examples intended to illustrate it.
As used herein, the “drawing power” of a polymer corresponds to the length of the polymer yarn obtained at the breaking point of the yarn according to the procedure defined below.
The drawing power of the polymers that may be used herein is the power measured for a composition containing (% by weight):
The drawing power is measured using a TA-TX2 texture analyzer (Rheo/stable Micro Systems).
The measurement is performed after compression of the product:
As used herein, the polymers with a drawing power of greater than 5 cm are referred to as drawing polymers.
The polymers with a drawing power of greater than 5 cm are chosen, for example, from (a1) a dispersion of particles of a water-soluble polymer with a weight-average molecular mass of greater than 106 in a saline aqueous solution, obtained by heterogeneous free-radical polymerization of water-soluble monomers with precipitation of the polymer formed, wherein at least one of the monomers is cationic, and (a2) an aqueous solution of a water-soluble polymer with a weight-average molecular mass of greater than 106, obtained by heterogeneous free-radical polymerization of water-soluble monomers with precipitation of the polymer formed, wherein at least one of the monomers is cationic.
The high molecular weight water-soluble polymer is a cationic or amphoteric polyelectrolyte, i.e., a polyelectrolyte polymerized using at least one cationic monomer of formula (I) as described below.
In one embodiment, the water-soluble polymers are cationic. The term “cationic polymer” includes polymers comprising cationic monomers and possibly nonionic monomers.
As indicated above, the synthesis of the high molecular weight water-soluble polymers, used herein, takes place by heterogeneous free-radical polymerization of water-soluble monomers comprising at least one ethylenic unsaturation. The polymerization takes place in an aqueous solution of a mineral electrolyte (salt) having an ionic strength that is sufficient to cause precipitation of the polymer formed as soon as it has reached a certain molecular mass. This polymerization technique thus allows, by virtue of the well-known phenomenon of salting out, the preparation of saline aqueous dispersions of water-soluble polymer particles. The polymers thus synthesized are distinguished by a high weight-average molecular mass, which is generally greater than 106.
The technique of heterogeneous free-radical polymerization in aqueous medium with precipitation of the polymer formed is described, for example, in U.S. Pat. No. 4,929,655, patent application EP 0 943 628 and International patent application WO 02/34796.
To ensure the stability of the dispersions of polymer particles during the synthesis and during storage, the polymerization is generally performed in the presence of a dispersant. This dispersant is, for example, a polyelectrolyte, which, unlike the high molecular weight polymer used herein, is soluble in the aqueous polymerization medium of high ionic strength.
This dispersing polyelectrolyte has, for example, a charge identical to that of the polymer synthesized. For example, for the synthesis of cationic polyelectrolytes, a cationic dispersing polyelectrolyte is generally used.
Examples of the dispersants that may be mentioned include the cationic polyelectrolytes obtained by polymerization of 50 to 100 mol % of at least one cationic monomer chosen from the salts, such as the hydrochlorides and sulfates, of dimethylaminoethyl (meth)acrylate, of N-dimethylaminopropyl(meth)-acrylamide and of di(meth)allylamine, (meth)acryloyloxy-ethyltrimethylammonium chloride, (meth)acrylamido-propyltrimethylammonium chloride and dimethyldiallyl-ammonium chloride, and of 50 to 0 mol % of acrylamide. A polyamine such as a polyalkyleneamine may, for example, also be used.
The dispersant is, for example, used in an amount ranging from 1% to 10% by weight relative to the total weight of the monomers to be polymerized.
The saline aqueous solution that serves as synthesis and dispersion medium for the high molecular weight water-soluble polymer is a solution of at least one mineral salt chosen, for example, from divalent anionic salts. Examples of anionic salts. that may be mentioned include ammonium sulfate, ammonium hydrogen sulfate, sodium sulfate, sodium hydrogen sulfate, magnesium sulfate, ammonium sulfate, magnesium hydrogen sulfate, aluminium sulfate and aluminium hydrogen sulfate. In one embodiment, at least one of ammonium sulfate and sodium sulfate is used.
The concentration of the at least one salt should, for example, be sufficient to induce the precipitation of the water-soluble polymer formed in the polymerization medium, and may be up to the saturation concentration of each salt. To obtain such a precipitation, the salt concentration is, for example, at least equal to 10% by weight, such as greater than 15% by weight and generally less than 50% by weight relative to the total weight of the polymer solution or dispersion. The saline aqueous solution may also comprise at least one monovalent salt, such as sodium chloride and ammonium chloride.
The heterogeneous free-radical polymerization in aqueous medium as described above is usually accompanied by a large increase in the viscosity of the reaction medium, which is reflected by difficulties in stirring, a lack of homogeneity of the reaction medium and an increase in the particle size of the polymer particles formed. To prevent such an increase in viscosity, it has been proposed, in European patent application EP 0 943 628, to add to the polymerization medium at least one agent for preventing the increase in viscosity of the reaction medium during polymerization.
The high molecular weight water-soluble polymers used herein are, for example, prepared in the presence of such an agent for preventing the increase in viscosity.
These agents for preventing the increase in viscosity of the reaction medium are chosen, for example, from:
The addition of at least one agent for preventing the increase in viscosity as described above makes it possible to perform the polymerization of the water-soluble monomers described above with a low-power stirrer while at the same time avoiding the formation of coarse particles. The agents for preventing an increase in viscosity are, for example, soluble in the aqueous reaction medium.
Examples of compounds (A) that may be mentioned include oxalic acid, adipic acid, tartaric acid, malic acid and phthalic acid, and the salts thereof.
Examples of compounds (B) that may be mentioned include resorcinol and pyrogallol.
Examples of compounds (C) that may be mentioned include m-hydroxybenzoic acid, p-hydroxy-benzoic acid, salicylic acid, gallic acid and tannic acid, and the salts thereof.
Examples of compounds (D) that may be mentioned include sodium gluconate, potassium gluconate, ammonium gluconate and various amine salts of gluconic acid.
Examples of compounds (E) that may be mentioned include those obtained by reacting a free-radical-generating compound, under a stream of oxygenated gas, in a solution comprising at least one monomer chosen from methoxy-hydroquinone and cationic (meth)acrylic monomers. The free-radical-generating compound may be an initiator commonly used for free-radical polymerization. Examples that may be mentioned include water-soluble azo initiators such as 2,2′-azobis(2-amidinopropane) hydrochloride sold, for example, under the name V-50 by the company Wako Chemical Industries, 2,2′-azobis[2-(2-imidazolin-2-yl)propane] hydrochloride sold, for example, under the trade name VA-044 by the company Wako Chemical Industries, and an initiator chosen from the water-soluble redox agents, such as the ammonium persulfate/sodium hydrogen sulfite combination.
An agent for preventing an increase in viscosity (F) may be obtained by reacting a free-radical initiator, under an oxygenated atmosphere, with a dispersant as disclosed herein. The polymerization initiator may be a water-soluble azo initiator or a water-soluble redox agent as described above.
The compounds (G) may be obtained in the form of oxidized polymers of low molecular mass by oxidation of a cationic dispersant as disclosed herein obtained by polymerization of a cationic (meth)acrylic monomer, using hydrogen peroxide or a halogen as oxidizing agent.
As cationic (meth)acrylic monomers used for the preparation of agents for preventing an increase in viscosity (E), (F) and (G), examples that may be mentioned include dimethylaminoethyl (meth)acrylate hydrochloride or sulfate, (meth)acryloyloxyethyl-trimethylammonium chloride, (meth)acryloyloxyethyl-dimethylbenzylammonium chloride, the hydrochloride or sulfate derived from N-dimethylaminopropyl(meth)-acrylamide, (meth)acrylamidopropyltrimethylammonium chloride, dimethylaminohydroxypropyl (meth)acrylate chloride or sulfate, (meth)acryloyloxyhydroxypropyl-trimethylammonium chloride and (meth)acryloyloxy-hydroxypropyldimethylbenzylammonium chloride.
These agents for preventing an increase in viscosity (A) to (G) may be used alone or as a mixture, in an amount ranging, for example, from 10 ppm to 10 000 ppm relative to the total weight of the reaction solution.
The water-soluble monomers polymerized by heterogeneous free-radical polymerization to obtain high molecular weight water-soluble polymers are monomers comprising at least one ethylenic double bond chosen, for example, from vinyl, acrylic and allylic double bonds. They may be cationic, anionic or nonionic and may be used as a mixture, wherein at least one monomer is cationic.
Examples of water-soluble anionic monomers that may be mentioned include acrylic acid, methacrylic acid, acrylamido-2-methylpropanesulfonic acid and itaconic acid. These anionic monomers are at least partially neutralized in the form of a salt of an alkali metal (for example sodium and potassium), of an alkaline-earth metal, of ammonium or of an organic amine such as an alkanolamine, for example, ethanolamine.

The mineral particles comprise, for example, at least one element chosen from columns IIa, IIIa and IVa, IIIb and IVb of the Periodic Table of the Elements, such as from columns IIa and IVa. They are chosen, for example, from particles comprising at least 10% by weight of calcium carbonate or of at least one silicate. Particles comprising at least 90% of aluminium oxide, silicas, magnesium oxide, zinc oxides, titanium oxides and barium sulfate, and mixtures thereof may also be used.
The solid mineral particles have, for example, a number-average primary size ranging from 2 nm to 2 microns, such as from 5 nm to 500 nm and further such as from 10 nm to 250 nm.
The particles as disclosed herein may, for example, be in any form, for example in the form of spheres, flakes, needles, platelets or totally random forms. In one embodiment, the particles are substantially spherical.
As used herein, the term “primary particle size” means the maximum size that it is possible to measure between two diametrically opposite points on an individual particle. The size may be determined, for example, by transmission electron microscopy or from the measurement of the specific surface area via the BET method, or alternatively by means of a laser granulometer.
In accordance with the present disclosure, the particle may be a solid particle formed entirely from calcium carbonate. Calcium carbonate may also totally or partially constitute the core of the particle, this core being covered with another constituent, for instance an oxide, a silicate or a metal. Calcium carbonate may also exclusively form the coating of a substrate of different chemical constitution, for instance an oxide, a silicate or a metal.
In the case where the particles are formed from calcium carbonate and from other fillers, the calcium carbonate is in free form and does not form chemical bonds with the other fillers. It is then a case of an alloy between the calcium carbonate and other fillers, such as with metal or metalloid oxides, obtained, for example, by melting of these various constituents.
When the particles comprising at least 10% by weight of calcium carbonate also comprise a metal or metalloid oxide, this oxide is, for example, chosen from silicon oxide, boron oxide and aluminium oxide.

The silicates that may be used according to the present disclosure may be chosen from sodium, magnesium and lithium silicates. The compounds sold by the company Laporte under the names Laponite XLG and Laponite XLS may, for example, be used.
When the particles comprising at least 10% by weight of at least one silicate also comprise a metal or metalloid oxide, this oxide is, for example, chosen from silicon oxide, boron oxide and aluminium oxide.
The silicates that are suitable in the compositions as disclosed herein may be of natural origin or of synthetic origin.
As glass particles that may be used herein, mention may be made of the hollow glass beads sold by the company 3M under the reference Scotchlite Glass Bubbles S22. 95% of these beads have a diameter of less than 74 μm.
Nylon particles that may be used are, for example, the “Orgasol” particles sold by the company Atochem. These particles are porous solid spheres with a diameter ranging, for example, from 5 μm to 60 μm.
In one embodiment, the particles are deformable hollow particles of an expanded copolymer of vinylidene chloride and of acrylonitrile or of vinylidene chloride, of acrylonitrile and of methacrylate. It is possible, for example, to use a terpolymer comprising: from 0% to 60% of units derived from vinylidene chloride, from 20% to 90% of units derived from acrylonitrile and from 0% to 50% of units derived from an acrylic or styrene monomer, the sum of the percentages (by weight) being equal to 100.

It is also possible to use particles of vinylidene chloride and of acrylonitrile polymer or of vinylidene chloride, of acrylonitrile and of non-expanded methacrylate polymer, for instance the products sold under the brand name Expancel with the references 551 DU 10 (particle size of about 10 μm) and 461 DU 15 (particle size of about 15 μm).
As other polymer particles that may be used herein, mention may also be made of the polymers and copolymers obtained from itaconic, citraconic, maleic and fumaric acids or esters, or from vinyl acetate or lactate. See in this respect document JP-A-2-112 304.
As used herein, the insoluble particles may be present in an amount ranging, for example, from 0.001% to 20% by weight, such as from 0.01% to 10% by weight and further such as from 0.1% to 3% by weight relative to the total weight of the final composition.
In one embodiment, the compositions may also comprise at least one cationic polymer other than the drawing polymer as disclosed herein.
The at least one cationic polymer that may be used herein may be chosen from all those already known per se as improving the cosmetic properties of the hair, for example, those described in European patent application EP-A-0 337 354 and in French patent applications FR-A-2 270 846; 2 383 660; 2 598 611; 2 470 596; and 2 519 863, and having a suitable cationic charge density.
Even more generally, as used herein, the term “cationic polymer” means any polymer comprising groups chosen from at least one of cationic groups and groups that may be ionized into cationic groups.
The cationic polymers are chosen, for example, from those comprising units comprising at least one amine group chosen from primary, secondary, tertiary and quaternary amine groups that either may form part of the main polymer chain or may be borne by a side substituent directly attached thereto.
The cationic polymers used generally have a number-average or weight-average molar mass ranging, for example, from 500 to 5×106 such as from 103 to 3×106.
