Description
Utilisation d'un sel de magnésium d'ester succinique acide comme émulsionnant On sait qu'un grand nombre de produits cosmétiques peuvent être avantageusement constitués par des émul sions du type eau dans l'huile . Mais de telles émul sions, qui doivent être stables, non renversables et de préférence fluides, sont très difficiles à obtenir dans l'état actuel de la technique.
En effet, la plupart des émulsions connues jusqu'à ce jour laissent échapper après un temps relativement court une certaine quantité d'eau et d'huile. Par ailleurs, il arrive très souvent que l'émulsion de départ du type eau dans l'huile se transforme spontanément en émul sion du type huile dans l'eau lorsqu'on y ajoute un excès d'eau.
La présente invention repose sur la découverte d'é- mulsionnants qui permettent d'obtenir facilement des émulsions stables et non renversables du type eau dans l'huile , les émulsions obtenues présentant la plupart du temps une grande fluidité. - , Les émulsions ainsi obtenues présentent un intérêt tout particulier dans le domaine de la cosmétique, car
EMI0001.0010
la la formule dans laquelle m est un nombre entier égal ou supérieur à 12 ; il est de préférence compris entre 12 et 13.
n et p sont des nombres de 0 à 12, la somme de n et p ayant une valeur de 2 à 12.
La proportion d'eau dans les émulsions préparées à l'aide de l'émulsionnant défini ci-dessus peut varier dans elles assurent une hydratation très efficace du complexe lipidoprotéidique qui constitue la couche cornée de la peau et évitent ainsi le dessèchement de celle-ci.
II semble que cette propriété remarquable de ces émulsions soit due non seulement aux particules d'eau qui sont retenues par la phase huileuse continue, mais surtout grâce au fait que les produits constitutifs des émulsions retiennent une très importante quantité d'eau lïée.
Cette caractéristique particulièrement avantageuse se vérifie par le fait que les émulsions étendues en couche mince ne se dessèchent que très lentement, même placées dans une atmosphère relativement sèche.
De plus, ces émulsions présentent le grand intérêt de favoriser la pénétration dans la peau des produits qui entrent dans la composition de l'émulsion. La présente invention a donc pour objet l'utilisation, comme émulsionnant, d'un sel de magnésium d'un mono- ester succinique d'alcool gras polyoxyalcoyléné de for mule % 10 300,10 de très larges limites, par exemple de 20 à 60 ,
tandis que la proportion d'émulsionnant peut varier d'environ â par rapport au total des constituants tout en éteint généralement d'au moins 20 0/o par rapport à l'huile.
On peut utiliser pour constituer la phase huile des émulsions une grande variété de produits tels que - des huiles hydrocarbonées, comme l'huile de pa raffine, la vaseline filante, le perhydrosqualène et les solutions de cire microcristalline dans l'huile de paraf fine, - des huiles animales ou végétales comme l'huile de cheval, la graisse de porc, l'huile d'amande douce, l'huile de calophyllum ;ces huiles étant bien absorbées par la peau mais pouvant dans certains cas donner lieu à rancissement, - des esters saturés non rancissables et bien péné trants comme le palmitate d'isopropyle, le myristate d'isopropyle, le palmitate d'éthyle, etc., - des huiles de silicone solubles dans les autres huiles.
On peut également utiliser comme adjuvants : des alcools gras à longue chaîne tels que l'alcool cétylique, l'alcool stéarylique, l'alcool gras de cire d'abeilles, le cholestérol, l'alcool de lanoline, du stéarate de magné sium.
Principalement lorsque les émulsions sont destinées à constituer des produits cosmétiques ou pharmaceutiques, il est préférable que l'eau qu'elles contiennent soit exempte d'électrolytes et de produits en solution.
Les émulsions préparées à l'aide de l'émulsionnant défini ci-dessus permettent de réaliser les produits cosmé tiques les plus divers tels que les crèmes hydratantes, fonds de teint, fards, crème fluide brillantante, etc.
Elles permettent également de réaliser d'excellents excipients médicaux doués d'un grand pouvoir de péné tration.
Pour préparer les sels de magnésium des monoesters succiniques tels que définis à la formule (T) ci-dessus, on peut opérer comme suit On fait réagir les alcools gras de C12 à C18 avec l'oxyde de propylène ou l'oxyde de butylène ou un mé lange de ces deux corps en présence d'un catalyseur alca lin (sodium ou méthylate de sodium par exemple; à rai son d'environ 0,1 à 0,5 % de sodium par rapport à l'alcool gras utilisé).
On effectue de préférence la réaction en autoclave sous pression à une température comprise entre 100 et l50> C. <I>Exemple 7</I> On prépare un lait hydratant qui a la composition suivante - Sel de magnésium du composé ayant la formule
EMI0002.0008
<I>Exemple 2</I> On prépare une crème hydratante qui a la composition suivante - Sel de magnésium du composé ayant la formule 4 Le produit obtenu est ensuite lavé avec une solution aqueuse de méthanol de 10 à 20 %.
On estérifie ensuite les alcools gras polyoxyalcoylénés avec de l'anhydride succinique en opérant en présence de pyridine à une température d'environ 90 à 100 C.
La réaction d'estérification dure environ 3 heures. En opérant avec des réactifs pris dans les proportions suivantes - 1 mole d'alcool polyoxyalcoyléné -<B>1,10</B> mole d'anhydride succinique - 2 moles de pyridine on obtient une estérification pratiquement complète. Pour préparer le sel de magnésium de l'ester ainsi obtenu, on neutralise le monoester succinique considéré par une quantité stachiométrique de KOH à 4011/o, en présence d'une quantité d'eau suffisante pour qu'en fin d'opération on obtienne une solution isotrope de concen tration N/3.
On effectue cette neutralisation sous forte agitation à une température d'environ 80 C.
On précipite extemporanément le sol de magnésium par un excès de chlorure de magnésium en solution. II suffit de procéder ensuite à deux lavages consécutifs pour obtenir le sel de magnésium recherché.
Pour préparer une émulsion, on petit dissoudre le sel de magnésium hydraté, qui a été obtenu comme il vient d'être dit, dans l'huile de l'émulsion, en opérant à une température de 80 C environ.
On agite ensuite fortement pendant que l'on verse la quantité d'eau voulue préalablement portée elle aussi à la température de 80 C environ. On refroidit tout en continuant à agiter.
La viscosité des émulsions obtenues dépend natu rellement de leur composition, mais il est possible d'ob tenir selon l'invention des émulsions très fluides en raison de ta solubilité des émulsionnants dans de nombreuses huiles.
Dans le but de mieux faire comprendre l'invention, on va en décrire maintenant à titre d'illustration plusieurs exemples de mise en aeuvre. Les compositions décrites dans ces exemples sont dans chaque cas obtenues en pré parant les émulsions comme il vient d'être indiqué.

EMI0004.0001
EMI0004.0002
Exemple 8
EMI0004.0003
Les émulsions constituant les produits décrits dans les exemples précédents sont du type (t eau dans
l'huile et pos- sèdent une bonne stabilité sans présenter le risque de se retourner en des émulsions du type e huile dans l'eau lorsqu'on y ajoute un excès d'eau.
Toutes ces émulsions permettent une hydratation très efficace de la couche cornée de la peau.
Les émulsionnants utilisés conformément à l'invention se prêtent particulièrement bien à la préparation de fonds de teint, de fards ou de crèmes pour les mains. Les fards notamment résistent à l'action de l'eau et ne s'éliminent qu'avec des laits ou des crèmes démaquillantes.
L'oxyde de titane et les pigments bien dispersés dans ces émulsions pénètrent remarquablement et couvrent la peau sans la charger. On remarquera à ce sujet la quantité inhabituellement grande d'oxyde de titane contenue dans la crème pour les mains selon l'exemple 4 ci-dessus.
Enfin, la complète inocuité et la bonne pénétration des émulsions font qu'elles constituent d'excellents excipients médicaux.
Il est clair que l'on peut utiliser simultanément plusieurs émulsionnants tels que définis.
Il va également de soi que l'on peut introduire dans les émulsions tous les ingrédients habituellement utilisés et en particulier ceux qui tendent à augmenter la stabilité et les facultés de conservation des émulsions.
Enfin, on comprendra que les émulsionnants tels que définis peuvent également être utilisés dans des domaines autres que ceux de la cosmétique et des excipients pour produits pharmaceutiques.
Use of a magnesium salt of an acid succinic ester as an emulsifier It is known that a large number of cosmetic products can advantageously consist of emulsions of the water-in-oil type. But such emulsions, which must be stable, non-reversible and preferably fluid, are very difficult to obtain in the current state of the art.
In fact, most of the emulsions known to date allow a certain quantity of water and oil to escape after a relatively short time. Furthermore, it very often happens that the starting emulsion of the water-in-oil type spontaneously transforms into an emulsion of the oil-in-water type when an excess of water is added thereto.
The present invention is based on the discovery of emulsifiers which make it possible easily to obtain stable and non-spillable emulsions of the water-in-oil type, the emulsions obtained mostly exhibiting great fluidity. - The emulsions thus obtained are of very particular interest in the field of cosmetics, because
EMI0001.0010
the formula wherein m is an integer equal to or greater than 12; it is preferably between 12 and 13.
n and p are numbers from 0 to 12, with the sum of n and p having a value from 2 to 12.
The proportion of water in the emulsions prepared using the emulsifier defined above may vary in that they ensure very effective hydration of the lipidoproteidic complex which constitutes the horny layer of the skin and thus prevent drying of the latter. .
It seems that this remarkable property of these emulsions is due not only to the water particles which are retained by the continuous oily phase, but above all thanks to the fact that the constituent products of the emulsions retain a very large quantity of water.
This particularly advantageous characteristic is verified by the fact that the emulsions spread in a thin layer only dry out very slowly, even when placed in a relatively dry atmosphere.
In addition, these emulsions have the great advantage of promoting the penetration into the skin of the products which go into the composition of the emulsion. A subject of the present invention is therefore the use, as an emulsifier, of a magnesium salt of a succinic monoester of polyoxyalkylenated fatty alcohol of the formula% 10 300.10 very wide limits, for example from 20 to 60,
while the proportion of emulsifier can vary from about based on the total constituents while generally quenching by at least 20% based on the oil.
A wide variety of products can be used to constitute the oil phase of emulsions, such as - hydrocarbon oils, such as refined paraffin oil, petrolatum, perhydrosqualene and solutions of microcrystalline wax in fine paraffin oil, - animal or vegetable oils such as horse oil, pork fat, sweet almond oil, calophyllum oil; these oils are well absorbed by the skin but can in some cases lead to rancidity, - saturated non-rancishable and well-penetrating esters such as isopropyl palmitate, isopropyl myristate, ethyl palmitate, etc., - silicone oils soluble in other oils.
The following can also be used as adjuvants: long-chain fatty alcohols such as cetyl alcohol, stearyl alcohol, beeswax fatty alcohol, cholesterol, lanolin alcohol, magnesium stearate.
Mainly when the emulsions are intended to constitute cosmetic or pharmaceutical products, it is preferable for the water they contain to be free from electrolytes and from products in solution.
The emulsions prepared using the emulsifier defined above make it possible to produce the most diverse cosmetic products such as moisturizers, foundations, eyeshadows, shining fluid cream, etc.
They also make it possible to produce excellent medical excipients endowed with a great penetrating power.
To prepare the magnesium salts of the succinic monoesters as defined in formula (T) above, one can operate as follows. The C12 to C18 fatty alcohols are reacted with propylene oxide or butylene oxide or a mixture of these two bodies in the presence of an alkaline catalyst (sodium or sodium methoxide for example; in an amount of approximately 0.1 to 0.5% sodium relative to the fatty alcohol used).
The reaction is preferably carried out in an autoclave under pressure at a temperature between 100 and 150> C. <I> Example 7 </I> A moisturizing milk is prepared which has the following composition - Magnesium salt of the compound having the formula
EMI0002.0008
<I> Example 2 </I> A moisturizer is prepared which has the following composition - Magnesium salt of the compound having the formula 4 The product obtained is then washed with a 10 to 20% aqueous methanol solution.
The polyoxyalkylenated fatty alcohols are then esterified with succinic anhydride by operating in the presence of pyridine at a temperature of about 90 to 100 C.
The esterification reaction lasts about 3 hours. By operating with reagents taken in the following proportions - 1 mole of polyoxyalkylene alcohol - <B> 1.10 </B> mole of succinic anhydride - 2 moles of pyridine, practically complete esterification is obtained. To prepare the magnesium salt of the ester thus obtained, the succinic monoester under consideration is neutralized with a stachiometric amount of KOH at 4011 / o, in the presence of a sufficient amount of water so that at the end of the operation one obtains an isotropic solution of N / 3 concentration.
This neutralization is carried out with vigorous stirring at a temperature of about 80 ° C.
The magnesium sol is precipitated extemporaneously with an excess of magnesium chloride in solution. It suffices then to carry out two consecutive washes to obtain the desired magnesium salt.
To prepare an emulsion, the hydrated magnesium salt, which was obtained as just said, is dissolved in the oil of the emulsion, operating at a temperature of approximately 80 ° C.
The mixture is then stirred vigorously while the desired quantity of water is poured in, also brought to a temperature of about 80 ° C. Cooled while continuing to stir.
The viscosity of the emulsions obtained naturally depends on their composition, but it is possible according to the invention to obtain very fluid emulsions because of the solubility of the emulsifiers in many oils.
In order to better understand the invention, several examples of implementation will now be described by way of illustration. The compositions described in these examples are in each case obtained by preparing the emulsions as has just been indicated.

The emulsions constituting the products described in the preceding examples are of the type (t water in
oil and have good stability without the risk of turning into oil-in-water emulsions when excess water is added.
All these emulsions allow very effective hydration of the horny layer of the skin.
The emulsifiers used in accordance with the invention are particularly suitable for the preparation of foundations, make-up or creams for the hands. In particular, eyeshadows are resistant to the action of water and can only be removed with milks or cleansing creams.
The titanium oxide and the well dispersed pigments in these emulsions penetrate remarkably and cover the skin without loading it. In this connection, the unusually large amount of titanium oxide contained in the hand cream according to Example 4 above will be noted.
Finally, the complete harmlessness and good penetration of emulsions make them excellent medical excipients.
It is clear that it is possible to simultaneously use several emulsifiers as defined.
It also goes without saying that it is possible to introduce into the emulsions all the ingredients usually used and in particular those which tend to increase the stability and the storage capacities of the emulsions.
Finally, it will be understood that the emulsifiers as defined can also be used in fields other than those of cosmetics and in excipients for pharmaceutical products.
