Description
La prĂ©sente invention concerne un traitement de surface de poudres, notamment pigments, afin dâamĂ©liorer la dispersion desdites poudres notamment dans une composition cosmĂ©tique. La prĂ©sente demande concerne la composition de poudres ainsi obtenue, le procĂ©dĂ© de traitement des poudres et lâutilisation de ces poudres traitĂ©es dans des compositions cosmĂ©tiques.The present invention relates to a surface treatment of powders, in particular pigments, in order to improve the dispersion of said powders in particular in a cosmetic composition. The present application relates to the powder composition thus obtained, the powder treatment process and the use of these treated powders in cosmetic compositions.
De nombreuses formulations cosmĂ©tiques comprennent des poudres dispersĂ©es Ă lâĂ©tat divisĂ©, typiquement des pigments. Lorsque les pigments sont dispersĂ©s de façon homogĂšne dans la formulation, sa couleur est homogĂšne et intense. La formulation devient plus stable et sa durĂ©e de vie est plus longue. Dans les formulations solaires, des poudres Ă lâĂ©chelle nanomĂ©trique sont utilisĂ©es comme filtres minĂ©raux pour absorber les rayonnements Ă la place de la peau. Plus ces poudres sont dispersĂ©es de façon homogĂšne, plus elles absorbent les rayonnements. La dispersion homogĂšne des pigments est ainsi une Ă©tape clĂ© dans une formulation et elle est assurĂ©e par une Ă©tape de broyage du pigment dans une des phases liquides de la formulation. Cette Ă©tape de broyage augmente le temps de fabrication et engendre un coĂ»t supplĂ©mentaire pour les formulateurs car il est nĂ©cessaire dâavoir un Ă©quipement adĂ©quat. Ainsi il semble important dâamĂ©liorer la dispersion des pigments afin dâĂ©liminer cette Ă©tape de broyage en formulation. De plus, dans le domaine cosmĂ©tique, il existe une demande croissante des produits de beautĂ© plus propres, plus sains, plus naturels et plus durables.Many cosmetic formulations include powders dispersed in a divided state, typically pigments. When the pigments are evenly dispersed in the formulation, its color is homogeneous and intense. The formulation becomes more stable and its shelf life is longer. In sunscreen formulations, nanoscale powders are used as mineral filters to absorb radiation instead of the skin. The more homogeneously these powders are dispersed, the more they absorb radiation. The homogeneous dispersion of the pigments is thus a key step in a formulation and it is ensured by a step of grinding the pigment in one of the liquid phases of the formulation. This grinding step increases manufacturing time and generates additional costs for formulators because it is necessary to have adequate equipment. It therefore seems important to improve the dispersion of pigments in order to eliminate this grinding step in formulation. Additionally, in the cosmetics field, there is a growing demand for cleaner, healthier, more natural and more sustainable beauty products.
JP2004182679 propose de traiter des pigments avec de lâextrait dâAloe Vera et de lâhuile de coco. Ce traitement est dĂ©crit comme permettant dâamĂ©liorer le toucher des poudres dans des formulations cosmĂ©tiques sĂšches telles que les poudres de compacts, il nâest nullement mentionnĂ© lâutilisation dans des dispersions dans un milieu liquide.JP2004182679 suggests treating pigments with Aloe Vera extract and coconut oil. This treatment is described as making it possible to improve the feel of powders in dry cosmetic formulations such as compact powders; there is no mention of the use in dispersions in a liquid medium.
WO2O10/111279, propose de traiter des pigments avec des molĂ©cules synthĂ©tiques comme par exemple la combinaison dâun agent dispersant tel que lâacide polyhydroxy stĂ©arique et dâun traitement hydrophobe tel que le triethoxycaprylylsilane afin dâamĂ©liorer la dispersion des pigments dans une formulation. Cependant, dans le domaine cosmĂ©tique, pour une question de sĂ©curitĂ© et de qualitĂ© environnementale, il est souvent souhaitable dâutiliser de moins en moins les produits synthĂ©tiques.WO2O10/111279, proposes treating pigments with synthetic molecules such as for example the combination of a dispersing agent such as polyhydroxy stearic acid and a hydrophobic treatment such as triethoxycaprylylsilane in order to improve the dispersion of pigments in a formulation. However, in the cosmetic field, for reasons of safety and environmental quality, it is often desirable to use synthetic products less and less.
EP0200839 propose de traiter des pigments par de la lĂ©cithine hydrogĂ©nĂ©e. La lĂ©cithine hydrogĂ©nĂ©e comporte des mono- et di-esters de phosphate comportant des chaĂźnes grasses. Une fois dĂ©posĂ©e sur le pigment, la lĂ©cithine hydrogĂ©nĂ©e favorise la dispersion de celui-ci, dans la phase huileuse. Lâutilisation de pigments traitĂ©s par de la lĂ©cithine hydrogĂ©nĂ©e dans une formulation cosmĂ©tique dont le milieu est huileux permet donc dâobtenir une coloration adĂ©quate sans Ă©tape de broyage. Cependant ce procĂ©dĂ© comprend une Ă©tape de mĂ©lange du pigment avec un additif dans un solvant typiquement une solution aqueuse, lâadditif pouvant ĂȘtre des sels dâaluminium, de magnĂ©sium, de calcium etc. Le mĂ©lange obtenu est ensuite filtrĂ© puis sĂ©chĂ© pour rĂ©cupĂ©rer les pigments traitĂ©s. NĂ©anmoins, lorsque les pigments sont des pigments de trĂšs faibles diamĂštres, typiquement des pigments dont les particules isolĂ©es prĂ©sentent un D50 infĂ©rieur Ă 0,5 ”m, ou lorsque les pigments sont trĂšs hydrophiles, ceux-ci passent Ă travers la membrane de filtration, limitant ainsi le rendement en pigment traitĂ©. Par ailleurs, la mise en Ćuvre de solution aqueuse et la nĂ©cessitĂ© dâune filtration entraĂźne des questions en terme de temps de traitement, dâĂ©nergie, dâenvironnement et de recyclage.EP0200839 proposes treating pigments with hydrogenated lecithin. Hydrogenated lecithin contains phosphate mono- and diesters with fatty chains. Once deposited on the pigment, hydrogenated lecithin promotes its dispersion in the oily phase. The use of pigments treated with hydrogenated lecithin in a cosmetic formulation with an oily medium therefore makes it possible to obtain adequate coloring without a grinding step. However, this process includes a step of mixing the pigment with an additive in a solvent, typically an aqueous solution, the additive possibly being salts of aluminum, magnesium, calcium, etc. The mixture obtained is then filtered and then dried to recover the treated pigments. However, when the pigments are very small diameter pigments, typically pigments whose isolated particles have a D50 less than 0.5 ”m, or when the pigments are very hydrophilic, they pass through the filtration membrane, limiting thus the yield of treated pigment. Furthermore, the use of an aqueous solution and the need for filtration raises questions in terms of treatment time, energy, environment and recycling.
Il y a donc un intĂ©rĂȘt de fournir un nouveau traitement des poudres.There is therefore an interest in providing a new powder treatment.
Un objectif de la prĂ©sente invention est de fournir un nouveau traitement de poudres, notamment pigments, permettant dâamĂ©liorer leur dispersion notamment dans les milieux liquides notamment les compositions cosmĂ©tiques, qui soit plus respectueux de lâenvironnement et mette en Ćuvre des composĂ©s biosourcĂ©s et permettant de traiter les poudres de toutes tailles.An objective of the present invention is to provide a new treatment of powders, in particular pigments, making it possible to improve their dispersion in particular in liquid media, in particular cosmetic compositions, which is more respectful of the environment and uses biosourced compounds and allowing you to process powders of all sizes.
Un autre objectif de la prĂ©sente invention est de fournir un procĂ©dĂ© de traitement plus rapide, consommant moins dâĂ©nergie et donc plus respectueux de lâenvironnement.Another objective of the present invention is to provide a faster treatment process, consuming less energy and therefore more environmentally friendly.

De prĂ©fĂ©rence, dans le macĂ©ra de lâinvention, le ratio en poids dâAloe Vera par rapport au poids dâhuile de coco est compris entre 0,1% et 10%, de prĂ©fĂ©rence entre 0,5% et 5%. De façon avantageuse, ce ratio permet de disperser trĂšs facilement les poudres en milieu huileux ou silicone ou dans la phase huileuse continue dâune Ă©mulsion eau dans huile.In the context of the present invention, the term Aloe Vera maceration in coconut oil is understood to mean a composition obtained by maceration of Aloe Vera in coconut oil, preferably it is a composition obtained by maceration of Aloe Vera leaves in coconut oil. Preferably, in the macera of the invention, the ratio by weight of Aloe Vera relative to the weight of coconut oil is between 0.1% and 10%, preferably between 0.5% and 5%. Advantageously, this ratio makes it possible to very easily disperse the powders in an oily or silicone medium or in the continuous oily phase of a water-in-oil emulsion.

Les pigments organiques adaptĂ©s Ă la mise en Ćuvre de lâinvention, peuvent ĂȘtre choisis parmi le carmin, les dĂ©rivĂ©s de colorants azoĂŻques, ou encore un pigment laquĂ©, câest-Ă -dire un colorant associĂ© Ă un support minĂ©ral qui le rend insoluble. Dans le cadre de la prĂ©sente invention on entend par colorant une substance colorĂ©e hydrosoluble ou liposoluble, au contraire un pigment est insoluble dans les milieux aqueux ou huileux.The organic pigments suitable for implementing the invention can be chosen from carmine, derivatives of azo dyes, or even a lacquered pigment, that is to say a dye associated with a mineral support which makes it insoluble. In the context of the present invention, the term dye is understood to mean a water-soluble or fat-soluble colored substance; on the contrary, a pigment is insoluble in aqueous or oily media.
Le pigment peut Ă©galement ĂȘtre choisi parmi les substrats comprenant un oxyde mĂ©tallique tel que par exemple les nacres, les oxydes mĂ©talliques ayant subi un traitement minĂ©ral par exemple silice, alumine; les composites comprenant une bille de polymĂšre ou minĂ©rale dĂ©corĂ©e de pigments ; des ingrĂ©dients tels que des colorants absorbĂ©s sur des polysaccharides (chitosan, maltodextrine, cellulose, gomme xanthan, pullulan etc.), des colorants absorbĂ©s sur des polymĂšres synthĂ©tiques ou naturels tels que des acides polyhydroxyalcaniques ou des charges minĂ©rales adsorbĂ©s de colorant et leurs mĂ©langes.The pigment can also be chosen from substrates comprising a metal oxide such as for example nacre, metal oxides having undergone a mineral treatment for example silica, alumina; composites comprising a polymer or mineral ball decorated with pigments; ingredients such as dyes absorbed on polysaccharides (chitosan, maltodextrin, cellulose, xanthan gum, pullulan etc.), dyes absorbed on synthetic or natural polymers such as polyhydroxyalkanic acids or mineral fillers adsorbed with dyes and their mixtures.

Les poudres de lâinvention peuvent ĂȘtre un mĂ©lange des poudres mentionnĂ©es ci-dessus.The powders of the invention can be a mixture of the powders mentioned above.
La liste des poudres mentionnĂ©es dans la prĂ©sente invention nâest pas exhaustive. De maniĂšre gĂ©nĂ©rale, toute poudre en cosmĂ©tique peut ĂȘtre traitĂ©e en surface selon cette invention pourvue quâelle soit sous forme de poudre.The list of powders mentioned in the present invention is not exhaustive. Generally speaking, any cosmetic powder can be surface treated according to this invention provided that it is in powder form.
De façon particuliĂšrement avantageuse, les poudres de lâinvention peuvent ĂȘtre de toute taille. Par exemple, les poudres (notamment pigment, charge, polymĂšre) prĂ©sentent un diamĂštre moyen Dv50 en volume, mesurĂ© par granulomĂ©trie laser en milieu aqueux, de 10 nm Ă 30 ”m. Cela comprend donc Ă©galement des particules Ă lâĂ©chelle nanomĂ©trique au sens de la rĂ©glementation cosmĂ©tique.Particularly advantageously, the powders of the invention can be of any size. For example, powders (in particular pigment, filler, polymer) have an average diameter D v 50 by volume, measured by laser particle size analysis in an aqueous medium, from 10 nm to 30 ”m. This therefore also includes particles at the nanoscale within the meaning of cosmetic regulations.
De façon particuliĂšrement avantageuse, le traitement des poudres avec de lâhuile de coco ou le macĂ©ra dâAloe Vera dans lâhuile de coco, permet de rendre la poudre hydrophobe et par consĂ©quent dâamĂ©liorer sa dispersion notamment dans les milieux liquides notamment compositions cosmĂ©tiques.Particularly advantageously, the treatment of powders with coconut oil or Aloe Vera macera in coconut oil makes it possible to make the powder hydrophobic and therefore to improve its dispersion, particularly in liquid media. cosmetic compositions.
De façon avantageuse, lâAloe Vera permet dâĂ©viter lâoxydation de lâhuile de coco et donc de la composition de poudre.Advantageously, Aloe Vera helps prevent the oxidation of coconut oil and therefore of the powder composition.
De prĂ©fĂ©rence, la composition de lâinvention comprend de 3 Ă 10% en poids dâhuile de coco ou dâun macĂ©ra dâAloe Vera dans lâhuile de coco par rapport au poids total de la composition.Preferably, the composition of the invention comprises from 3 to 10% by weight of coconut oil or an Aloe Vera macera in coconut oil relative to the total weight of the composition.
De prĂ©fĂ©rence, la composition de lâinvention comprend :
- De 85 Ă 99% en poids de poudre ;
- De 1 Ă 15% en poids dâhuile de coco ou dâun macĂ©ra dâAloe Vera dans lâhuile de coco,
- From 85 to 99% by weight of powder;
- From 1 to 15% by weight of coconut oil or Aloe Vera macera in coconut oil,
les pourcentages Ă©tant en poids par rapport au poids total de la composition.the percentages being by weight relative to the total weight of the composition.
Sans vouloir ĂȘtre liĂ© par une quelconque thĂ©orie, dans la composition de poudres de lâinvention, la poudre, lâhuile de coco ou le macĂ©ra dâAloe Vera dans lâhuile de coco, sont intimement mĂ©langĂ©s, lâhuile de coco ou le macĂ©ra Ă©tant en gĂ©nĂ©ral adsorbĂ© Ă la surface des poudres par les liaisons intermolĂ©culaires telles que les liaisons HydrogĂšne et les liaisons de Van Der Walls.Without wishing to be bound by any theory, in the powder composition of the invention, the powder, the coconut oil or the Aloe Vera macera in the coconut oil, are intimately mixed, the coconut oil or the macera being generally adsorbed on the surface of the powders by intermolecular bonds such as Hydrogen bonds and Van Der Walls bonds.
Ainsi, la composition de poudre selon lâinvention est une composition solide.Thus, the powder composition according to the invention is a solid composition.
La composition de poudre selon lâinvention est destinĂ©e Ă ĂȘtre dispersĂ©e dans un milieu liquide, de prĂ©fĂ©rence un milieu huileux, silicone ou dans la phase huileuse dâune Ă©mulsion eau dans huile, de prĂ©fĂ©rence ledit milieu liquide est ou fait partie dâune composition cosmĂ©tique.The powder composition according to the invention is intended to be dispersed in a liquid medium, preferably an oily medium, silicone or in the oily phase of a water-in-oil emulsion, preferably said liquid medium is or forms part of a cosmetic composition.
De façon particuliĂšrement avantageuse, le traitement des poudres permet dâamĂ©liorer la dispersibilitĂ© des poudres notamment dans les milieux liquides, notamment les milieux huileux, silicone ou dans la phase huileuse dâune Ă©mulsion eau dans huile, et plus prĂ©fĂ©rentiellement dans les compositions cosmĂ©tiques.In a particularly advantageous manner, the treatment of powders makes it possible to improve the dispersibility of the powders, particularly in liquid media, notably oily media, silicone or in the oily phase of a water-in-oil emulsion, and more preferably in cosmetic compositions.
De façon avantageuse, lorsque la poudre est un pigment, le traitement de lâinvention permet un dĂ©veloppement rapide, complet et homogĂšne de lâintensitĂ© colorielle et un ajustement facile de la teinte souhaitĂ©e en formulation cosmĂ©tique.Advantageously, when the powder is a pigment, the treatment of the invention allows rapid, complete and homogeneous development of the color intensity and easy adjustment of the desired shade in cosmetic formulation.
De façon avantageuse du fait de la stabilitĂ© et de la fluiditĂ© de la composition de poudre selon lâinvention, il est possible dâajouter une quantitĂ© plus importante de poudre, notamment pigment, dans les milieux liquides dans lesquels ils sont dispersĂ©s. Il est ainsi possible de disperser une quantitĂ© plus importante de poudre dans les compositions cosmĂ©tiques, notamment les compositions huileuses, silicones ou Ă©mulsion, lorsque les poudres ont Ă©tĂ© traitĂ©es par lâinvention, tout en limitant lâaugmentation de la viscositĂ©. Il est donc possible de prĂ©parer une composition cosmĂ©tique dont lâextrait sec en poudre est plus Ă©levĂ©. Cela permet notamment, lorsque la poudre est un pigment, dâobtenir une composition cosmĂ©tique avec une meilleure couvrance. Cela permet Ă©galement une meilleure application des formulations cosmĂ©tiques.Advantageously, due to the stability and fluidity of the powder composition according to the invention, it is possible to add a larger quantity of powder, in particular pigment, to the liquid media in which they are dispersed. It is thus possible to disperse a larger quantity of powder in cosmetic compositions, in particular oily, silicone or emulsion compositions, when the powders have been treated by the invention, while limiting the increase in viscosity. It is therefore possible to prepare a cosmetic composition with a higher dry powder extract. This makes it possible, in particular, when the powder is a pigment, to obtain a cosmetic composition with better coverage. This also allows for better application of cosmetic formulations.
La prĂ©sente demande concerne Ă©galement un procĂ©dĂ© de prĂ©paration de la composition selon lâinvention comprenant la pulvĂ©risation de lâhuile de coco ou du macĂ©ra dâAloe Vera dans lâhuile de coco tel que dĂ©crit ci-dessus Ă la surface de la poudre. La composition est ensuite chauffĂ©e Ă une tempĂ©rature comprise entre 30 et 120°C pour sĂ©cher la composition. Lâhomme du mĂ©tier saura adapter la tempĂ©rature en fonction de la nature, notamment chimique, de la poudre.The present application also relates to a process for preparing the composition according to the invention comprising spraying coconut oil or Aloe Vera macera in coconut oil as described above on the surface of the powder. . The composition is then heated to a temperature between 30 and 120°C to dry the composition. A person skilled in the art will know how to adapt the temperature according to the nature, particularly chemical, of the powder.
Le procĂ©dĂ© peut Ă©galement comprendre une Ă©tape, aprĂšs sĂ©chage, de micronisation ou broyage. Selon la nature des poudres, les tailles de particules Ă lâissue du procĂ©dĂ© peuvent ĂȘtre comprises entre 5 nm et 50 ”m.The process can also include a step, after drying, of micronization or grinding. Depending on the nature of the powders, the particle sizes at the end of the process can be between 5 nm and 50 ”m.
De façon gĂ©nĂ©rale, lorsque des poudres sont utilisĂ©es dans les compositions cosmĂ©tiques il est nĂ©cessaire pour le formulateur de prĂ©-disperser les poudres dans la composition puis de broyer la composition obtenue pour avoir une bonne dispersion des poudres. Avantageusement, le procĂ©dĂ© de traitement des poudres selon lâinvention permet de sâaffranchir de cette prĂ©-dispersion et de ce broyage pour la prĂ©paration de la composition cosmĂ©tique. Le procĂ©dĂ© de prĂ©paration de la composition cosmĂ©tique comprenant la composition de poudre selon lâinvention peut donc ĂȘtre mis en Ćuvre sans broyeur, ce qui permet de diminuer le coĂ»t et le temps de production de la composition cosmĂ©tique.Generally, when powders are used in cosmetic compositions it is necessary for the formulator to pre-disperse the powders in the composition then to grind the composition obtained to have good dispersion of the powders. Advantageously, the powder treatment method according to the invention makes it possible to dispense with this pre-dispersion and this grinding for the preparation of the cosmetic composition. The process for preparing the cosmetic composition comprising the powder composition according to the invention can therefore be implemented without a grinder, which makes it possible to reduce the cost and time of production of the cosmetic composition.

Méthode de caractérisation des compositions pigmentairesMethod for characterizing pigment compositions
Les méthodes décrites ci-aprÚs sont utilisées dans les principaux tests de caractérisation illustrés dans les exemples qui suivent :
- HydrophobicitĂ© (mesure de lâangle de contact)
- PrĂ©paration de la poudre compacte : une poudre compacte est prĂ©parĂ©e Ă lâaide dâune compacteuse laboratoire Tecnocoll dans un godet en mĂ©tal de 3,5 mL. La pression est maintenue Ă 50 bar pendant 10 secondes.
- Mesure de lâangle de contact : 4 ”L dâeau est dĂ©posĂ©e sur la poudre compacte. Lâangle de contact du liquide sur le solide peut alors ĂȘtre mesurĂ©e grĂące au goniomĂštre DSA30. Dans le cas de lâeau, si lâangle de contact est infĂ©rieur Ă 90 °, alors la poudre est considĂ©rĂ©e comme hydrophile. Si lâangle de contact est supĂ©rieur Ă 90 °, alors la poudre est considĂ©rĂ©e comme hydrophobe. Plus cette valeur est Ă©levĂ©e, plus la poudre sera hydrophobe.
- Viscosité dynamique
- PrĂ©paration de 30 g de dispersion du pigment dans le Caprylic/Capric Triglyceride : le pigment est mĂ©langĂ© dans le Caprylic/Capric Triglyceride pendant 5 minutes Ă lâaide dâun agitateur magnĂ©tique pendant 3 minutes. Les quantitĂ©s des produits sont ajustĂ©es en fonction des pourcentages en masse souhaitĂ©e.
- Mesure de la viscosité dynamique : Elle est mesurée avec un viscosimÚtre du laboratoire (Brookfield DV2T). Le profile rhéologique se fait en utilisant le mobile SC4-34 à 20 °C.
- Capacité à se disperser facilement dans une formulation cosmétique
- PrĂ©paration de la dispersion : 50.0 g de Covanol White ON 9787 (de Sensient Cosmetic Technologies) et de lâoctyldodecanol sont mĂ©langĂ©s au Rayneri, 10.7 g de Covanol Red OS 3705 (de Sensient Cosmetic Technologies) est ensuite rajoutĂ©. 15 g du mĂ©lange prĂ©cĂ©dent est prĂ©levĂ© et est mis dans un pot de speedmixer, 1 g de pigment est ensuite rajoutĂ©. Lâensemble est mis sous agitation dans un mĂ©langeur de laboratoire (Hauschild SpeedMixer DAC 150 FVZ-K) pendant 1 minute. La vitesse dâagitation est de 2000 tour/min. Une dispersion fluide est obtenue.
- 4 gouttes de dispersion prĂ©parĂ©e prĂ©cĂ©demment sont dĂ©posĂ©es entre 2 plaques de verre. LâhomogĂ©nĂ©itĂ© de la dispersion est observĂ©e. Le pigment ou la composition pigmentaire est considĂ©rĂ© comme facilement dispersible lorsque la dispersion prĂ©parĂ©e est homogĂšne, aucune prĂ©sence de grain nâest observĂ©e.
- Hydrophobicity (contact angle measurement)
- Preparation of the compact powder: a compact powder is prepared using a Tecnocoll laboratory compactor in a 3.5 mL metal cup. The pressure is maintained at 50 bar for 10 seconds.
- Contact angle measurement: 4 ”L of water is deposited on the compact powder. The contact angle of the liquid on the solid can then be measured using the DSA30 goniometer. In the case of water, if the contact angle is less than 90°, then the powder is considered hydrophilic. If the contact angle is greater than 90°, then the powder is considered hydrophobic. The higher this value, the more hydrophobic the powder will be.
- Dynamic viscosity
- Preparation of 30 g of pigment dispersion in Caprylic/Capric Triglyceride: the pigment is mixed in Caprylic/Capric Triglyceride for 5 minutes using a magnetic stirrer for 3 minutes. The quantities of the products are adjusted according to the desired mass percentages.
- Measurement of dynamic viscosity: It is measured with a laboratory viscometer (Brookfield DV2T). The rheological profile is carried out using the SC4-34 mobile at 20°C.
- Ability to disperse easily in a cosmetic formulation
- Preparation of the dispersion: 50.0 g of Covanol White ON 9787 (from Sensient Cosmetic Technologies) and octyldodecanol are mixed with Rayneri, 10.7 g of Covanol Red OS 3705 (from Sensient Cosmetic Technologies) is then added. 15 g of the previous mixture is taken and put in a speedmixer pot, 1 g of pigment is then added. The whole is stirred in a laboratory mixer (Hauschild SpeedMixer DAC 150 FVZ-K) for 1 minute. The stirring speed is 2000 rpm. A fluid dispersion is obtained.
- 4 drops of dispersion prepared previously are placed between 2 glass plates. The homogeneity of the dispersion is observed. The pigment or pigment composition is considered to be easily dispersible when the dispersion prepared is homogeneous, no presence of grain is observed.
5,0 g du macĂ©ra dĂ©crit prĂ©cĂ©demment est mĂ©langĂ© avec 95,0 g de dioxyde de titane (Nom commercial : Unipure White LC987 de Sensient Cosmetic Technologies). Le mĂ©lange final est mis Ă lâĂ©tuve pendant 6h sous 40 °C puis la poudre est broyĂ©e afin dâobtenir les tailles de particules initiales du dioxyde de titane non traitĂ©. On obtient la composition pigmentaire A.5.0 g of the macera described above is mixed with 95.0 g of titanium dioxide (Trade name: Unipure White LC987 from Sensient Cosmetic Technologies). The final mixture is placed in an oven for 6 hours at 40°C then the powder is crushed in order to obtain the initial particle sizes of the untreated titanium dioxide. Pigment composition A is obtained.

Par rapport au pigment non traitĂ© (lâUnipure White LC987) le traitement de la prĂ©sente invention illustrĂ© par lâexemple 1 permet dâobtenir une composition pigmentaire A hydrophobe qui a la capacitĂ© de se disperser aisĂ©ment dans une formulation cosmĂ©tique. Le mĂ©lange Ă 40% en poids de 12 g de la composition pigmentaire dans 18 g dâune huile cosmĂ©tique (exemple ici du Caprylic/Capric Triglyceride) est Ă©galement plus fluide.Compared to the untreated pigment (Unipure White LC987) the treatment of the present invention illustrated by Example 1 makes it possible to obtain a hydrophobic pigment composition A which has the capacity to easily disperse in a cosmetic formulation. The mixture at 40% by weight of 12 g of the pigment composition in 18 g of a cosmetic oil (example here of Caprylic/Capric Triglyceride) is also more fluid.
La
La viscositĂ© dâune dispersion de pigment dans un milieu liquide augmente avec le taux de charge pigmentaire. Au-delĂ dâun certain seuil, la dispersion devient trop visqueuse ou pĂąteuse et il nâest alors plus possible de mesurer sa viscositĂ©.The viscosity of a pigment dispersion in a liquid medium increases with the pigment loading rate. Beyond a certain threshold, the dispersion becomes too viscous or pasty and it is then no longer possible to measure its viscosity.
Dans le cas de lâUnipure White LC987, avec le viscosimĂštre Brookfield DV2T et le mobile SC4-34, quel que soit la vitesse, il est possible de mesurer sa viscositĂ© dans le Caprylic/Capric Tryglicerides jusquâĂ 25% en poids. A 30% en poids, il nâest plus possible de mesurer la viscositĂ© Ă partir de 200 tours par minute. A 40% en poids, la dispersion devient trop pĂąteuse, la mesure de la viscositĂ© ne peut se faire au-delĂ de 0,2 tour par minute.In the case of the Unipure White LC987, with the Brookfield DV2T viscometer and the SC4-34 mobile, whatever the speed, it is possible to measure its viscosity in Caprylic/Capric Tryglicerides up to 25% by weight. At 30% by weight, it is no longer possible to measure viscosity from 200 revolutions per minute. At 40% by weight, the dispersion becomes too pasty, the viscosity measurement cannot be done beyond 0.2 revolutions per minute.
Dans le cas de lâUnipure White LC987 traitĂ© (Composition pigmentaire A), dans les mĂȘmes conditions que prĂ©cĂ©demment, il est possible de mesurer sa viscositĂ© Ă 40% en poids en tout point. Le profile rhĂ©ologique est par ailleurs similaire Ă celui de lâUnipure White LC987 Ă 25% en poids. ComparĂ© au pigment non traitĂ©, le traitement de la prĂ©sente invention permet dâaugmenter la charge pigmentaire dâau moins 60% en poids en formulation cosmĂ©tique liquide tout en gardant la mĂȘme fluiditĂ©.In the case of treated Unipure White LC987 (Pigment Composition A), under the same conditions as above, it is possible to measure its viscosity at 40% by weight at any point. The rheological profile is also similar to that of Unipure White LC987 at 25% by weight. Compared to untreated pigment, the treatment of the present invention makes it possible to increase the pigment load by at least 60% by weight in liquid cosmetic formulation while maintaining the same fluidity.

Les traitements au beurre dâavocat et Ă la composition selon lâinvention permettent tous deux de rendre les pigments hydrophobes. Le mĂ©lange des compositions pigmentaires dans une huile cosmĂ©tique (exemple ici du Caprylic/Capric Triglyceride) est Ă©galement fluide.The treatments with avocado butter and the composition according to the invention both make it possible to make the pigments hydrophobic. The mixture of pigment compositions in a cosmetic oil (example here of Caprylic/Capric Triglyceride) is also fluid.
