Description

NOUVEAU LATEX INVERSE CONCENTRE, PROCEDE POUR SA PREPARATION, ET UTILISATION DANS L'INDUSTRIE La présente demande concerne des latex inverse eau dans huile épaississants, leur procédé de préparation et leur application en tant qu'épaississant et/ou émulsionnant dans les produits industriels, les produits de soins de la peau et des cheveux ou pour la iabrica- tion de préparations cosmétiques, dermopharmaceutiques ou pharmaceutiques. Les latex inverses de polymères de l'acide l'acide 2-méthyl 2-[(l-oxo 2-propènyl) amino] 1-propanesulfonique (dénommé aussi acide 2-acrylamido 2-méthyl propanesulfoni- que, ATBS ou AMPS) partiellement ou totalement salifié ainsi que leur utilisation en cos- métique et/ou pharmacie ont fait de nombreuses demandes de brevet. Cependant la présence de quantités importantes d'eau et d'huile représente un inconvénient non négligeable en termes de volume, de coût et parfois de risques accrus et/ou d'effets toxiques. Des solutions ont donc été développées pour augmenter la concentration en polymères dans les latex finaux par exemple en soumettant le milieu réactionnel en fin de polyméri- sation, à une étape de distillation sous vide pour enlever une partie plus ou moins importante d'eau et d'huile. Cette distillation est cependant délicate à mettre en œuvre car elle induit souvent une déstabilisation du latex inverse qu'il faut contrer par l'addition préalable d'agents stabilisants. Les demandes de brevet européen EP 0 161 038 et EP 0 126528 ainsi que la demande de brevet britannique GB 1 482 515 divulguent une telle utilisation de po- lymères stabilisants. Mais ceux-ci contiennent des alcools ou des glycols qui induisent des problèmes environnementaux. De plus il se produit parfois une prise en masse du milieu réactionnel lors de l'étape de distillation sans que ce phénomène n'ait jamais vraiment été expliqué, mais dont la conséquence certaine est la destruction du lot de latex inverse et un nettoyage pénible et coûteux du réacteur. Enfin, même quand la distillation se déroule correctement, les latex inverses obtenus s'inversent souvent difficilement, ils ont une viscosité élevée et présentent parfois en leur sein des micro-gels. Ces inconvénients interdisent donc leur utilisation dans la fabrication de formulations cosmétiques et ou d'impression textile. C'est pourquoi la demanderesse s'est attachée à mettre au point des latex inverses concentrés, c'est à dire comprenant au moins 50 % en poids de polymère et moins de 5 % en poids d'eau dépourvus de tels inconvénients. Selon un premier aspect, l'invention a pour objet une composition sous forme d'un latex inverse comprenant : a) de 50 % en poids à 80 % d'au moins un polymère organique (P) linéaire, branché ou réticulé, b) de 5 % en poids à 10 % d'un système émulsionnant (Si) de type eau dans huileFIELD OF THE INVENTION The present application relates to water-in-oil thickening inverse latexes, their method of preparation and their application as thickeners and / or emulsifiers in industrial products, skin and hair care products or for the manufacture of cosmetic, dermopharmaceutical or pharmaceutical preparations. Inverse polymer latexes of 2-methyl-2 - [(1-oxo-2-propenyl) amino] 1-propanesulfonic acid (also referred to as 2-acrylamido-2-methylpropanesulfonic acid, ATBS or AMPS) partially or fully salified and their use in cosmetics and / or pharmacy have made many patent applications. However, the presence of significant amounts of water and oil represents a significant disadvantage in terms of volume, cost and sometimes increased risks and / or toxic effects. Solutions have therefore been developed to increase the concentration of polymers in the final latexes, for example by subjecting the reaction medium at the end of polymerization, to a vacuum distillation stage to remove a greater or lesser part of water and water. 'oil. This distillation is however difficult to implement because it often induces destabilization of the inverse latex which must be countered by the prior addition of stabilizing agents. European Patent Applications EP 0 161 038 and EP 0 126528 and British Patent Application GB 1 482 515 disclose such use of stabilizing polymers. But these contain alcohols or glycols that induce environmental problems. In addition, the reaction medium is sometimes taken up in the distillation stage without this phenomenon having really been explained, but the undeniable consequence of which is the destruction of the batch of inverse latex and a painful and difficult cleaning. expensive reactor. Finally, even when the distillation proceeds correctly, the inverse latexes obtained are often inverted with difficulty, they have a high viscosity and sometimes have within them micro-gels. These disadvantages therefore prohibit their use in the manufacture of cosmetic formulations and or textile printing. This is why the applicant has endeavored to develop concentrated inverse latexes, that is to say comprising at least 50% by weight of polymer and less than 5% by weight of water without such disadvantages. According to a first aspect, the subject of the invention is a composition in the form of an inverse latex comprising: a) from 50% by weight to 80% of at least one linear, branched or crosslinked organic polymer (P), b) from 5% by weight to 10% of an emulsifier system (Si) of water-in-oil type
(E/H), c) de 5 % en poids à 45 % en poids d'au moins une huile, et d) de 0 % à 5 % d'eau. Le polymère (P) présent dans la composition objet de l'invention peut être un homo- polymère ou un polymère formé à partir de plusieurs types différents de monomères. H s'agit principalement d'un copolymère, d'un terpolymère ou d'un tétrapolymère. La composition telle que définie précédemment contient, soit un seul polymère (P), soit un mélange de polymères (P) différents. Selon un premier aspect particulier de la présente invention, le polymère (P) est - s jt un homopolymère d'un monomère choisi ou bien parmi ceux possédant une fonction acide fort partiellement ou totalement salifiée ou bien parmi ceux possédant une fonction acide faible partiellement ou totalement salifiée ou bien parmi les monomères canoniques, - s jt un copolymère dans lequel chacun des monomères est choisi indépendamment l'un de l'autre ou bien parmi ceux possédant une fonction acide fort partiellement ou totalement salifiée ou bien parmi ceux possédant une fonction acide faible partiellement ou totalement salifié ou bien parmi les monomères neutres ou bien parmi les monomères cationi- ques, - s jt un terpolymère dans lequel chacun des monomères est choisi indépendamment les uns des autres ou bien parmi ceux possédant une fonction acide fort partiellement ou totalement salifiée ou bien parmi ceux possédant une fonction acide faible partiellement ou totalement salifié ou bien parmi les monomères neutres ou bien parmi les monomères canoniques, - spjt un tétrapolymère dans lequel chacun des monomères est choisi indépendam- ment les uns des autres ou bien parmi ceux possédant une fonction acide fort partiellement ou totalement salifiée ou bien parmi ceux possédant une fonction acide faible partiellement ou totalement salifié ou bien parmi les monomères neutres ou bien parmi les monomères ca- tioniques. Dans la composition telle que définie ci-dessus, le système émulsionnant (Si) de type eau dans huile (E H) est constitué soit d'un seul tensioactif soit d'un mélange de tensioactifs à condition que ledit mélange ait une valeur de HLB suffisamment faible pour induire des émulsions eau dans huile. Comme agent émulsionnant de type eau - dans huile, il y a par exemple les esters de sorbitan, comme le l'oléate de sorbitan, comme celui commerciahsé par la société SEPPIC sous le nom MONTANE™ 80, l'isostéarate de sorbitan, comme celui commerciahsé par la société SEPPIC sous le nom MONTANE™ 70 ou le sesquioléate de sorbitan comme celui commercialisé par la société SEPPIC sous le nom MONTANE™ 83. Il y aussi certains esters de sorbitan polyéthoxylés, par exemple le monooléate de sorbitan pentaéthoxylé comme celui commercialisé par la société SEPPIC sous le nom MONTA- NOX™ 81 ou l'isostéarate de sorbitan pentaéthoxylé comme celui commerciahsé sous le nom MONTANOX™ 71 par la société SEPPIC. Il y a encore l'alcool oléocétylique dié- thoxylé comme celui commerciahsé sous le nom SBvIULSOL™ OC 72 par la société SEPPIC, Pacrylate de lauryle tétraéthoxylé comme celui commercialisé sous le nom BLEM- MER™ ALE 200 ou les polyesters de poids moléculaire compris entre 1000 et 3000, produits de la condensation entre un acide poly(iosbutènyl) succinique ou son anhydride et un polyéthylène glycol, tels que 1ΗYPERMER™ 2296 commercialisé par la société UNI- CHEMA ou enfin les copolymères blocks de poids moléculaire compris entre 2500 et 3500, comme 1ΗYPERMER™ B246 commerciahsé par la société UNICHEMA ou le SEvIA- LINE™ IE 200 commercialisé par la société SEPPIC. Par polymère branché, on désigne pour (P), un polymère non linéaire qui possède des chaînes pendantes de manière à obtenir, lorsque ce polymère est mis en solution dans l'eau, un fort état d'enchevêtrement conduisant à des viscosités à bas gradient très importantes. Par polymère réticulé, on désigne pour (P), un polymère non linéaire se présentant à l'état de réseau tridimensionnel insoluble dans l'eau, mais gonflable à l'eau et conduisant donc à l'obtention d'un gel chimique. La composition selon l'invention peut comporter des motifs linéaires, des motifs réticulés et/ou des motifs branchés. Lorsque le polymère (P) est réticulé, il l'est plus particulièrement avec un composé diéthylènique ou polyéthylènique dans la proportion molaire exprimée par rapport aux monomères mis en oeuvre, de 0,005% à 1%, et de préférence de 0,01 % à 0,2 % et, plus particulièrement de 0,01 % à 0,1 %. De préférence l'agent de réticulation et/ou l'agent de rami- fication est choisi parmi le diméthacrylate d'éthylèneglycol, le diacrylate de diéthylèneglycol, le diallyloxyacétate de sodium, le diacrylate d'éthylèneglycol, le diallyl urée, le triallylarûine, le triméthylol propanetriacrylate ou le méthylène-bis-(acrylamide). La fonction acide fort des monomères en comportant est notamment la fonction acide sulfonique ou la fonction acide phosphonique. Lesdits monomères sont par exemple l'acide styrènesulfonique partiellement ou totalement salifié ou, de préférence, l'acide 2- méthyl 2-[(l-oxo 2-propènyl) amino] 1-propanesulfonique (dénommé aussi acide 2- acrylamido 2-méthyl propanesulfonique) partiellement ou totalement salifiée.
