Description

The present invention relates to cosmetic compositions, in particular for cleaning or washing keratin materials, in particular hair, in the form of an anhydrous solid, as well as a cosmetic treatment process using them.

Many cosmetic washing products are known in the field of hair hygiene. They are generally intended to clean keratin materials while providing them with good cosmetic properties. The conventional products for cleaning keratin materials, such as shampoos, are most often in the form of more or less thickened liquids. But these products can be difficult to measure: the more liquid they are, the more they tend to escape between the fingers, making their dosage difficult and wasteful, and / or tend to flee out of their packaging, which can be very embarrassing when they come into contact with clothing, for example when traveling. To modify the texture, and in particular to make it more compact, the conventional means consist in using thickeners, but this is often done to the detriment of the cosmetic effects of the composition. In addition, it has been found that thicker compositions often have the disadvantage of requiring a lot of rinse water to remove excess product on the hair. In many countries where access to water is limited, the flushing time and thus the quantity needed to rinse the product are key indicators of the qualities of use of a composition.

In order to overcome some of these problems, solid cosmetic formulations have been proposed, especially shampoos in the form of granules or solid powder. US4330438 which describes powdered shampoo concentrates comprising anionic surfactants and nonionic galactomannan derivatives which form shampoos after dilution with water. It can also be mentioned EP796318 which describes solid compositions obtained by drying and granulation of aqueous surfactant pastes in the presence of solid fillers, such as wood flours. We can also mention W02009 / 153311 which describes granulated shampoos comprising at least one surfactant deposited on solid particles. In this document, an aqueous phase comprising the surfactant is brought into contact with a solid phase consisting of charges, so that the surfactant 40 agglomerates on the charges. This step may be carried out in a granulator mixer, in a mixer or in a fluidized bed granulator. However, the solid compositions thus prepared can disintegrate or disintegrate with difficulty in the presence of water, and do not always make it possible to obtain a rapid foam start and / or an abundance of sufficient foam. They can also be difficult to remove on rinsing, and may leave residues on the hair, which may impact the cosmetic or aesthetic performance of the product. There is therefore the need to have compositions for washing keratin materials, which do not flow, which are more compact, modelable and economical. The desired compositions must disintegrate or disintegrate easily, be easy to apply to keratinous materials, and allow rapid foam initiation, that is to say the rapid obtaining of a suitable foam and sufficiently abundant, when the composition is applied, generally by rubbing, on said keratinous substances optionally previously moistened.

The object of the present invention is to propose such compositions which do not have the drawbacks of the prior art and which can rapidly make it possible to obtain a foam suitable for washing keratin materials.

The subject of the invention is therefore a solid anhydrous cosmetic composition, in the form of particles, comprising: at least 30% by weight, relative to the total weight of the composition, of one or more anionic surfactants, at least 5% by weight, relative to the total weight of the composition, of one or more amphoteric surfactants, at least 10% by weight, relative to the total weight of the composition, of one or more fillers. Another subject of the invention is a process for preparing an anhydrous solid cosmetic composition, by granulation on a fluidized air bed, in which: a liquid phase comprising a solvent is sprayed, on a solid phase comprising at least 50% by weight, relative to the total weight of said solid phase, of one or more surfactants chosen from anionic and amphoteric surfactants, and mixtures thereof.

The composition according to the invention has a very unusual, non-sticky texture; it is easy to collect, handle and apply, the composition is easily prehensible, very easily dosable and applicable. It disintegrates easily and quickly in contact with water, and allows rapid foam, good performance and abundant amount, quite comparable to the growth obtained with a cleaning composition, by example of type shampoo, usual. The composition also rinses easily, leaving no residue on the hair, while giving a natural and clean feel to keratin materials after elimination. The composition according to the invention may be packaged in the form of a single dose, which is particularly advantageous for example in the context of travel or sport or hiking (lightened luggage, limitation of the risk of leakage of the product in the bags , waste reduction).

In general, and known to those skilled in the art, it can be said that the granulation of particles in fluidized air bed is a method of contacting three phases: solid, liquid and gas. It is a complex process that brings together simultaneous and competitive steps such as mixing, spraying, wetting, drying. The principle is relatively simple: the solid particles are suspended in the bed by a stream of hot air and a solution containing the binder is injected into it. The heat required to evaporate the solvent is provided by the fluidizing air. This technique has the advantage of performing several operations such as wetting, mixing and drying in the same apparatus. The agglomeration of wet solid particles in a fluidized bed results from a succession of elementary steps, namely the wetting of the surface of the particles by the liquid (binder), the collision and the adhesion of particles to each other. These steps all occur in the same device. The particle charge is set in motion by an upward flow of hot air (fluidizing air), allowing individualization and mixing of the particles. The spraying of liquid in the bed makes it possible to wet the surface of the particles coming into contact with the jet, making it sticky. Depending on the conditions of drying by hot air, the deposited liquid (drop) will serve, in contact with another particle, to establish a bridge (or a bond) liquid which will be solidified by drying. The repetition of the wetting, colliding and drying stages leads to growth by agglomeration (or coalescence) which is sought after. Because of the agitation of the bed, the agglomerates are subjected to shocks, and there is competition between coalescence and rupture.

The different equipment used for agglomeration aims to put the particles in contact with the drops of binder solution, then the particles wetted together. The operation can be discontinuous or continuous, with the possibility of recycling fines for example. A preferred embodiment of the preparation of the composition according to the invention is described below; this mode is only illustrative and in no way limiting. Thus, according to this preferred embodiment: in a fluidized bed, the solid phase (comprising the solid particles) is set in motion (the particles are individualized) by an updraft of hot air (or gas). Spraying the liquid phase in fine drops (10-50 microns for example) above or within the fluidized bed of particles allows the wetting of their surface. Due to the strong agitation, the wet particles collide allowing the formation of liquid bridges between particles, bridges which are solidified very rapidly by drying (evaporation of water and / or solvent) under the effect of hot air flow. During the agglomeration of particles in a fluidized bed, the surface of the particles is wetted by spraying a liquid phase above the bed. A nozzle provides a jet of dispersed liquid that will contact the circulating particles. Preferably, the atomization pressure is around 500-900 m3 / h, in particular 600-800 m3 / h. As is known, it has been found that the spray pressure can have a direct influence on the size of the spray solution droplets and on the spray angle. The higher the pressure, the finer the droplets and the smaller the spray angle. The fine droplets will dry more quickly on the powder already present in the chamber, thus allowing the particle size of the mixture to gradually increase and to form granules. On the other hand, with a lower pressure, the size of the droplets will be increased which will take longer to dry. In this case, the agglomeration phenomenon will be favored to that of granulation. Preferably, in the context of the invention, we must carry out granulation to obtain the most spherical particles possible, the spray pressure then being rather high. The hardness can be improved by increasing the number of layers (thus the size) without affecting the spray pressure, but rather the spray time and / or the formula.

The types of atomizers (or nozzles) used can be chosen from: - the turbine atomizers: the liquid is introduced in the center of the rotating disc and follows the path to the edge of the disc driven by the centrifugal force, where it is disintegrated in drops. The jet has an angle of 1800 and forms a cloud of drops. The average diameter of the drops produced is in particular from 1 to 600 microns. - Pressurized atomizers (single-fluid): the jet is formed by converting the pressure energy into kinetic energy when the liquid passes through the nozzle under pressure (5 to 7 MPa). The liquid enters the atomizer tangentially and exits the orifice in the form of a jet with an angle that varies between 40 ° and 140 °. The range of drop diameters formed is generally from 10 to 800 microns. - the pneumatic atomizers (bi-fluids): they make it possible to obtain different modes of spraying, with hollow cone, with solid cone or with flat jet. The angle of the spray jet varies between 20 ° and 60 ° depending on the configuration of the nozzle. The pressure of the compressed air used is 0.15 to 0.8 MPa. The dispersion of the liquid into small drops (5 to 300 microns) is ensured by the shearing forces exerted by the atomizing air (or gas) on the liquid phase. During the agglomeration of solid particles in a fluidized bed, various phenomena are involved: the wetting of the surface of the fluidized particles (by the sprayed liquid), the collision between the wet particles, the formation of liquid bridges (effective adhesion between sufficiently wet particles, sticky on the surface), the drying of liquid bridges, transformed into solid bridges (consolidation of the agglomerates), and the attrition of the agglomerates (related to the mechanical strength and agitation of the agglomerates formed). Preferably, the temperature in the fluidized air bed is between 30 and 60 ° C, especially between 35 ° C and 45 ° C. In the process chamber, it is possible to record 3 temperatures: the temperature of the incoming air which is generally of the order of 80-90 ° C .; the temperature of the product, which is generally of the order of 50-60 ° C; and the outlet temperature which is generally of the order of 40-50 ° C. The cosmetic composition may be rinsed or not rinsed after being applied to the keratin materials; preferably it is rinsed after a possible exposure time which may be a few minutes. The cosmetic composition according to the invention finds a particularly advantageous application in the field of personal and / or hair hygiene, in particular for cleaning the hair and / or the scalp, as well as for cleaning and / or removing make-up from the skin. skin of the body and / or face. It can thus constitute a shampoo or a shower gel, or a mask to rinse. Advantageously, a small quantity of anhydrous composition is taken according to the invention, which is solubilized / pre-emulsified with water, for example in the hand, so as to form an abundant and immediate foam, which is then applies to keratin materials, and in particular hair and / or leather; then proceed in the same manner as with a usual liquid shampoo. The anhydrous composition can also be applied directly to the keratin materials, for example the hair, add a little water for example to the head, and rub / massage so as to solubilize / pre-emulsify said composition, and thus obtain a foam abundant and immediate; then proceed in the same manner as with a usual liquid shampoo. It is also possible to wet the keratin materials, for example the hair, then to apply the composition directly on it, and to exert a friction to disintegrate the particles and thus obtain an abundant and immediate foam; then proceed in the same manner as with a usual liquid shampoo. The amount of anhydrous composition that can be taken / applied can for example be of the order of 1 to 3 g. It can then be left for a few minutes, then rinse, for example with water, so as to eliminate the foam and dirt.

The subject of the invention is therefore also a process for the cosmetic treatment, in particular of care and / or cleaning, of keratinous substances, in particular the hair, the scalp, the skin of the body and / or the face, comprising the application on said keratin materials, a cosmetic composition according to the invention, optionally followed by rinsing, after a possible exposure time. The invention relates in particular to a cosmetic process for cleaning human keratin materials, in which a composition according to the invention is applied to said keratin materials, in the presence of water, is massed to form a foam, and then the formed foam is removed and soiling by rinsing with water after a possible exposure time. The present invention is further illustrated in the following examples (MA = active ingredient). Example 1 A / A hair-cleaning composition was prepared in the following manner: Batch Process A Procell (Glatt) fluidized-bed granulator apparatus was used with a conical chamber Type Insert GF 3 of useful volume of 2.5 liters to 10 liters. The spraying guide is pumped into a reservoir and then sprayed into the chamber where the powder is set in motion by a fluidized air bed. The air is filtered above the chamber, and the filters are dusted regularly to recycle the fine particles.

A solid phase and a liquid phase of the following composition (in g) are prepared: Amount (in g) of% MA material in the initial composition in the final phases anhydrous after pas-solid and liquid before placing into the granulator process of the sprayed liquid powder process LAURYL SODIUM SULFATE (TEXAPON Z 95 P from Cognis) (100% MA) 294.6 58.9 45 + 9 (total = 54%) NaCl 40 6.1% P010 (JR400) 32, 7 5% Starch of potato (SODIUM CARBOXYMETHYL STARCH) at 94% MA in water GLYCOLYS of Roquette 32.7 5% COCO BETAINE at 30% MA in water 621.9 28.5% Total 400 g 680.8 g 61.1% + 37.5% (the remainder being residual water) Additional addition of water Bone to reach a pumpable and sprayable viscosity (less than 500 g) The raw materials used in the composition of the solid phase are premixed and then 400 g of the mixture is introduced into the spray chamber.

The raw materials used in the composition of the liquid phase are pre-mixed then the preparation is introduced into a tank provided with a peristaltic pump system for supplying the spray nozzle. The active ingredient content of the liquid phase to be prepared is directly determined by the amount of powder introduced into the granulation chamber.

The viscosity of the preparation is adjusted by adding water to adapt to the maximum viscosities allowed by the pumping system. The solvent of the liquid phase being evaporated during the granulation, the initial dilution of the liquid phase does not impact the final composition of the product. However, it is carried out sparingly so as not to lengthen the time required by the process with too much spray liquid. The test ends after spraying the entire liquid phase. Finally, an anhydrous solid composition is obtained in the form of particles of spherical shape, which can be sieved in order to extract the particles of required size, for example ranging from 630 pm to 1 mm. The residual water content does not exceed 5% by weight. Continuous process The composition can also be obtained with a continuous preparation mode in order to obtain larger quantities of product, for example with a device of the type ProCe1125 (from Glatt). The solid phase is then introduced continuously into the granulation chamber using a powder metering device by adjusting the flow rate with respect to the spray rate of the liquid phase to guarantee the final composition. The solid phase is gradually introduced into the granulation chamber where it is set in motion by the fluidized air bed. The air flow in the enclosure is about 700 m3 / h. The liquid phase is sprayed with 4 nozzles placed at the bottom of the granulation chamber; the atomization pressure is about 2 bar; the temperature of the product is about 50 ° C with an inlet temperature of about 80 ° C and an outlet of about 45 ° C; the temperature in the fluidized air bed is adjusted to 40 ° C. The granules discharged from the granulation chamber pass through a double sieve system making it possible to retain only the target fraction (approximately 630 μm-1 mm in size). The granules not entering this target fraction pass through a mill where they are milled and then recycled to the granulation chamber. Finally, an anhydrous solid composition is obtained in the form of particles of size ranging from 630 μm to 1 mm, of spherical shape. The residual water content does not exceed 5% by weight.

B / Evaluation The disintegration of the composition (obtained above, batch process) is evaluated by friction: 2 g of the composition prepared above is deposited on a mal- léable head previously wet, and it is rubbed slightly so that generating foam by kneading; the disintegration is evaluated after 10 frictions. Disintegration is considered fast if there are no particles visible to the naked eye. In this case, the disintegration is very fast. It is also found that the anhydrous composition according to the invention makes it possible to generate an abundant and creamy foam. Then, rinsed with water and evaluated the possible presence of residue after rinsing. The composition according to the invention leaves no residue.
