Description

Title of the invention: Cosmetic packaging article comprising a solid composition comprising a phosphated starch

[0001] The present invention relates to a packaging article comprising a multi-layer polymer-based envelope defining a cavity, and a solid composition comprising a phosphated starch, said composition being contained in the cavity defined by the envelope.

[0002] The invention also relates to a method for the cosmetic treatment of keratin materials, in particular human keratin fibers such as hair, using such a conditioning article, as well as the use of said conditioning article for the care of keratin materials, in particular human keratin fibers such as hair.

[0003] In the field of hair hygiene, care (or conditioning) products for keratin fibers are generally intended to condition said fibers to provide them with good cosmetic properties. Conventional products, such as conditioners, are most often in a more or less thickened liquid form. Due to their liquid texture, these products can, however, have various drawbacks, and in particular can be difficult to dose.

[0004] Indeed, the more liquid they are, the more they tend to escape between the fingers, making their dosage difficult and leading to waste. These products can also leak out of their packaging, which can cause inconvenience to the consumer when these products come into contact with clothing or objects, for example when moving.

[0005] In order to modify the texture of these products, and in particular to make it more compact, thickeners are generally used. The addition of these compounds, however, is often to the detriment of the cosmetic effects of the compositions. The use of these thicker compositions also requires a lot of rinsing water in order to eliminate the excess product on the fibers. However, in many countries where access to water is restricted, the rinsing time and consequently the quantity of water necessary to properly rinse the product are key indicators of the usability of a composition.

[0006] In order to overcome some of these problems, new solid cosmetic formulations, including conditioners in the form of solid granules or powders, have been developed. Such formulations are described, for example, in US 2021 / 007960. However, these new formulations do not always provide complete satisfaction. Those in the form of loose powder can indeed pose problems of volatility, gripping and / or dosage. Those in the form of agglomerates, such as granules for example, can tend to disintegrate or disintegrate with difficulty in the presence of water, adversely impacting their use and their spreading on the keratin fibers, and do not always allow satisfactory care to be obtained. They can also be difficult to remove when rinsing and sometimes even leave residues on the fibers that are unpleasant for the consumer.

[0007] Conditioners in powder or particle form may lose fluidity during storage due to the clumping of the solid unit particles together, which may negatively impact the qualities of use.

[0008] These formulations may also not give complete satisfaction in terms of cosmetic performance, particularly in terms of flexibility, feel, softness, detangling, smoothing, and shine.

[0009] Thus, there is a real need to provide a packaging article comprising a composition in solid form and having an improved environmental profile, in particular linked to the reduction in the use of plastic and the reduction in pollution linked to transport.

[0010] The packaging article must also be easily graspable, allow easy storage of the composition it contains, and allow easy dosing of the composition.

[0011] The packaging article and the composition it contains must dissolve and disintegrate easily.

[0012] The composition must furthermore confer satisfactory cosmetic properties, in particular in terms of suppleness, feel, softness, shine and detangling, in particular when it is in the form of a hair care composition, such as a conditioner.

[0013] It has now been discovered that a particular packaging article comprising a solid composition comprising at least one phosphated starch, makes it possible to achieve the objectives set out above, and in particular to be easily grasped and to dissolve and disintegrate easily, without lumps, without leaving residue on the hair after rinsing.

[0014] The present invention therefore relates to a packaging article comprising:

[0015] - an envelope defining at least one cavity, the envelope being composed of at least at least two layers assembled together in order to form only one unitary film,

[0016] the first layer comprising at least 60% by weight, relative to the total weight of the first layer, of one or more compounds chosen from cellulosic polymers, plant fibers and their mixtures, and

[0017] the second layer comprising at least 75% by weight, relative to the total weight of the second layer, of one or more vinyl alcohol polymers,

[0018] - a solid composition comprising one or more phosphated starches,

[0019] it being understood that said solid composition is located in at least one of the cavities defined by the envelope.

[0020] This packaging article makes it possible in particular to solve the problems of dosing the solid composition. It also facilitates its storage and transport. In particular, the packaging article of the invention offers better protection of the composition against humidity.

[0021] The packaging article of the invention dissolves easily and quickly in water, thus requiring little water during its use.

[0022] The presence of a phosphated starch makes it possible in particular to improve the dissolution of the packaging article and of the solid composition which it comprises.

[0023] Furthermore, this method of packaging is particularly interesting, for example, when traveling or playing sports (lighter bags, reduced risk of leaks, reduced waste).

[0024] The packaging article, when it comprises several cavities, can also make it possible to offer, for example, a shampoo and a conditioner in the same article.

[0025] Furthermore, this composition contained in the article disintegrates rapidly upon contact with water and allows, if necessary, to easily and quickly obtain a creamy, thick, non-sticky composition, comparable to a conventional liquid conditioner composition. This composition can then be distributed easily and homogeneously on the keratin fibers.

[0026] Furthermore, the composition of the invention rinses quickly without leaving unpleasant residues on the fibers and gives them a natural and clean feel after rinsing. The fibers treated with the composition of the invention also have good cosmetic properties, particularly in terms of softness, suppleness, and feel. They are also well individualized and thus easier to untangle.

[0027] The invention also relates to a method for cosmetic treatment, in particular care, of keratin fibers, in particular human keratin fibers such as hair, comprising a step of implementing at least one packaging article as defined above.

[0028] Other objects, characteristics, aspects and advantages of the invention will appear even more clearly on reading the description and the example which follows.

[0029] In what follows, and unless otherwise indicated, the limits of a domain of values are included in this domain, in particular in the expressions “between” and “ranging from ... to ...”.

[0030] Furthermore, the expression “at least one” used in the present description is equivalent to the expression “one or more”.

[0031] Furthermore, terms such as "first" or "second" used herein do not imply a sequence or order, unless the context clearly indicates so.

[0032] Packaging article The present invention relates in particular to a packaging article comprising: - an envelope defining at least one cavity, the envelope being composed of at least two layers assembled together in order to form only one unitary film, the first layer comprising at least 60% by weight, relative to the total weight of the first layer, of one or more compounds chosen from cellulosic polymers, plant fibers and their mixtures, and the second layer comprising at least 75% by weight, relative to the total weight of the second layer, of one or more vinyl alcohol polymers.

[0033] Preferably, the packaging article is a cosmetic packaging article. By "cosmetic packaging article" is meant an article suitable for cosmetic use; in particular for use of the packaging article on keratin materials, in particular hair and / or on the scalp. In particular, the packaging article makes it possible to wash and / or condition keratin fibers, in particular human keratin fibers such as hair.

[0034] Preferably, the packaging article according to the invention is water-soluble at a temperature less than or equal to 35°C.

Thus, when water preferably having a temperature less than or equal to 35°C is added to the packaging article, the envelope will dissolve and release the solid composition present in one of the cavities of the envelope.

[0037] The term “temperature less than or equal to 35°C” means a temperature not exceeding 35°C but greater than or equal to 0°C, for example ranging from more than 1 to 35°C, preferably from 5 to 30°C, more preferably from 10 to 30°C, and better still from 15 to 25°C.

The quaternizing agent may in particular be diallyldimethylammonium chloride (for example Celquat L200 from NATIONAL STARCH). As another cationic cellulose ether, mention may be made of hydroxyethyl cellulose hydroxypropyltrimethylammonium (for example Ucare polymer JR 400 from AMERCHOL).

[0049] Mention may also be made of celluloses or their derivatives, modified by groups comprising at least one fatty chain such as alkyl, arylalkyl, al-kylaryl groups or their mixtures where the alkyl groups are C8-C22; non-ionic alkylhydroxyethylcelluloses such as the products NATROSOL PLUS GRADE 330 CS and POLYSURF 67 (C16 alkyl) sold by the company AQUALON; quaternized (cationic) alkylhydroxyethylcelluloses such as the products QUATRISOFT LM 200, QUATRISOFT LM-X 529-18-A, QUATRISOFT LM-X 529-18-B (C12 alkyl) and QUATRISOFT LM-X 529-8 (C18 alkyl) sold by the company AMERCHOL, the products CRODACEL QM, CRODACEL QL (C12 alkyl) and CRODACEL QS (C18 alkyl) sold by the company CRODA and the product SOFTCAT SL 100 sold by the company AMERCHOL; non-ionic nonoxynylhydroxyethylcelluloses such as the product AMERCELL HM-1500 sold by the company AMERCHOL;non-ionic alkylcelluloses such as the product BERMOCOLL EHM 100 sold by the company BEROL NOBEL.;

[0050] Preferably, the compound(s) chosen from cellulosic polymers, plant fibers and their mixtures are chosen from wood pulp, carboxymethylcelluloses, as well as their sodium salts, and their mixtures.

[0051] Preferably, the compound(s) chosen from cellulosic polymers, plant fibers and their mixtures are present in the first layer in a content greater than or equal to 70% by weight, more preferably greater than or equal to 75% by weight, more preferably still greater than or equal to 80% by weight, better still greater than or equal to 90% by weight and even better still greater than or equal to 95% by weight, relative to the total weight of the first layer.

[0054] The method for measuring water uptake is described in WO 2017 / 218449. The water capacity is measured with a DVS (Dynamic Vapor Sorption) instrument of type SPS-DVS (model SPSx-A-High load with permeability kit) from ProUmid. The DVS uses gravimetry to determine sorption / moisture desorption and is fully automated. Measurements are taken at 20°C. Relative humidity (RH) is set at 35% (35%RH) for 6 hours and then gradually increased to 50% (50%RH) over 5 minutes. The relative humidity is then left at 50% for 12 hours. The total measurement time is 18 hours. Water uptake (or %Dm) represents the relative change in mass compared to the initial weight of the layer or film, i.e. 10% reflects a 10% increase in the weight of the layer or film compared to the initial weight. The water intake (or %Dm gained on the cycle at 50%RH during the fixed time of 12 hours at 20°C) is calculated by the difference between the %Dm value at 50%RH (last value measured at 50%RH) and %Dm at 35%RH (last value before rising to 50%RH).

[0055] Advantageously, the first layer has a breaking strength of between 40 and 80 N, preferably between 50 and 70 N.

[0088] The first layer and the second layer are assembled together to form a single unitary film. This unitary film makes it possible to define the envelope of the packaging article according to the invention.

[0089] Film is understood to mean in particular a continuous layer preferably formed from one or more polymers as defined above, in particular water-soluble.

[0090] It is understood that the invention is not limited to an envelope formed by a single first layer and a single second layer. In particular, the envelope of the packaging article may comprise several first layers and / or several second layers. In these embodiments, all of the first and second layers are assembled in order to form only a single unitary film.

[0091] The main industrial methods for producing polymer films are extrusion of a molten polymer, casting a solution of a polymer onto a polished metal surface (in some cases, the polymer solution is introduced into a precipitation tank), casting a dispersion of the polymer onto a polished surface and calendering.

[0092] The films usable according to the present invention can be chosen from multilayer film-film, film-paper (coating) and film-coating.

[0093] When applied by spraying, brushing or various industrial processes, surface coatings undergo what is called film formation, and in particular film-coating. In most film-forming processes, a relatively low-viscosity liquid coating is applied to a solid substrate and cured into a solid, adherent film based on a high molecular weight polymer having the properties desired by the user.

[0094] The assembly of the different layers together can be carried out by applying heat, for example by using a heating lamp or a heating roller.

[0095] Preferably, the second layer is adhesive. In this way, the first and second layers can adhere together to form the unitary film.

[0096] Particularly preferably, the second layer is adhesive on one of its faces. In this case, the first layer is assembled on this adhesive face of the second layer.

[0097] In a first embodiment of the invention, the first layer is formed and then covered with the second layer.

[0098] In another embodiment of the invention, the second layer is formed and then covered with the first layer.

[0099] In these embodiments of the invention, the coated layer may undergo a treatment to promote adhesion of the layer covering it, such as a treatment corona and / or plasma surface, reuse of a bonding layer between layers of the present films, application of an adhesive, and / or texturing methods.

[0100] Preferably, the film(s) defined by the layers are sealed to form one or more cavities which will comprise the solid composition defined below and prevent it from escaping.

[0101] In a particular embodiment, the first layer forms the exterior and the second layer forms the interior of the envelope of the packaging article.

[0102] In another particular embodiment, the first layer forms the interior and the second layer forms the exterior of the envelope of the packaging article.

[0103] The packaging article, as well as the envelope, may have any shape suitable for the intended use, for example a square, rectangular, round or oval shape. Preferably, it has a rounded geometry, for example in the form of a sphere, disc, or oval, or else square or parallelepiped, preferably with rounded corners. The envelope preferably has dimensions allowing it to be grasped between at least two fingers. Thus, it may have, for example, an ovoid shape of approximately 2 to 10 cm long and approximately 0.5 to 4 cm wide, or a circular disc shape of approximately 2 to 10 cm in diameter, or a square shape of approximately 2 to 15 cm on each side, or a rectangle shape of approximately 2 to 25 cm in length, it being understood that it may have any other shape and dimension suitable for the intended use.

[0104] Preferably, the envelope may be round in shape with an internal diameter ranging from 2 to 7 cm, more preferably from 4 to 5 cm; to which may be added the dimension of the edges (sealed part) which may range from 1 to 5 mm, better still from 2 to 4 mm; and a height ranging from 2 to 7 mm, preferably from 3 to 5 mm.

[0105] The envelope may also be square or rectangular in shape with a length preferably ranging from 2 to 7 cm, more preferably from 3 to 5 cm, and a width preferably ranging from 2 to 5 cm, more preferably 2.5 to 4 cm; to which may be added the dimension of the edges (sealed part) which may preferably range from 1 to 5 mm, and more preferably from 2 to 4 mm.

It has been observed that when the surface of the article is in the above ranges, the compaction of the solid composition into powder is lower and the transformation of the powder into a fluid composition in the hands is done more easily, without the formation of agglomerates.

[0107] Preferably, the height of the envelope is greater than or equal to 2mm, more preferably ranging from 2 to 10mm, and better still from 3 to 7mm.

[0108] The first layer and / or the second layer may optionally comprise indications in printed form, thermal relief or be the subject of a stamp. Preferably, when they are present, said indications are on the layer forming the outer part of the envelope, and more preferably on the external surface of said layer forming the outer part of the envelope.

[0110] Preferably, the solid composition according to the invention (final composition, after drying) has a water activity of less than 0.75, better still less than 0.72, even better still less than 0.70. The water activity, Aw, represents the proportion of bound water relative to free water which is conducive to the development of microorganisms. The value varies between 0 and 1. The activity is 0 for a completely dry product and it is 1 for pure water.

[0111] The solid composition according to the invention may comprise water added during its preparation and / or water which may come from the raw materials used during the preparation of said composition.

[0112] The solid composition according to the invention may be in the form of powder, paste, particles (for example spherical particles such as small beads or granules), compressed tablet, stick or loaf. Preferably, the composition according to the invention is in the form of powder or particles.

[0113] By "powder" is meant a composition in powder form, preferably essentially free of dust (or fine particles). In other words, the particle size distribution is such that the weight ratio of particles which have a size less than or equal to 50 μm (fines ratio), preferably less than or equal to 45 μm (fines ratio) is advantageously less than or equal to 5% by weight, preferably less than 3% by weight and more particularly less than 1% by weight, relative to the total weight of particles (particle size evaluated using a RETSCH AS 200 DIGIT granulometer; Oscillation height: 1.25 mm / sieving time: 5 minutes).

[0114] By "paste" is meant a composition having a viscosity greater than 0.5 Pa.s (5 poises) and preferably greater than 1 Pa.s (10 poises), measured at 25°C and at a shear rate of 1 s 1 ; this viscosity can be determined using a cone-plate rheometer.

[0115] By "particles" is meant small fractionated objects formed of solid particles aggregated together, of variable shapes and sizes. They may be of regular or irregular shape. In particular, they may be of spherical shape (such as granules, pellets, balls), square, rectangular, or elongated like rods. Spherical particles are particularly preferred.

[0116] Advantageously, the solid composition is in powder form.

[0119] When the solid composition according to the invention is not in the form of powder or particles, it advantageously has a penetration force at 25°C and 1 atm, greater than or equal to 200 g, preferably greater than or equal to 300 g, more preferably greater than or equal to 400 g, and better still greater than or equal to 500 g. The penetration force is determined by penetrometry. The texture analysis measurements are carried out at 25°C using a Stable Micro Systems TA.XT Plus texturometer. The penetrometry experiments are carried out with a metal rod equipped with a screwed tip, said tip being a 2 mm P / 2N needle for the upper part, connected to the measuring head. The piston is pushed into the sample at a constant speed of 1 mm / s, to a height of 5 mm. The force exerted on the piston is recorded and the average value of the force is calculated.

[0122] Phosphated starches The solid composition contained in the packaging article according to the invention comprises one or more phosphated starches.

[0123] Phosphated starches can be obtained by crosslinking with phosphorus compounds of monostarch phosphates (of the type Am-O-P0-(OX)2), distarch phosphates (of the type Am-O-PO-(OX)-O-Am) or even tristarch (of the type Am-O-PO- (O-Am)2) or mixtures thereof; with Am meaning starch and X designating in particular alkali metals (for example sodium or potassium), alkaline earth metals (for example calcium, magnesium), ammonia salts, amine salts such as those of monoethanolamine, diethanolamine, triethanolamine, 3-aminopropanediol-1,2, ammonium salts derived from basic amino acids such as lysine, arginine, sarcosine, ornithine, citrulline.
