Description

PROCEDE POUR L'OBTENTION D'UN PRODUIT GERMICIDE ET ENDURCISSANT LA PEAU.
L'utilisation des aldéhydes spécialement du formaldéhyde comme désinfectant est bien connus mais ces substances ont des effets désagréables étant donné qu'elles attaquent fortement la peau, en particulier les membranes muqueuses et les parties de la peau blessées.
On a trouvé que les produits de condensation des aldéhydes, spécialement le formaldéhyde avec des oxyaldéhydes ou des cétones ne montrent pas ces effets secondaires désagréables, si les matières ne participant pas à la réaction de condensation sont séparées après la condensation ou sont combinées par l'addition de matières réagissant avec le groupe d'aldéhydes ou de cétones.
Les aldéhydes à employer sont le formaldéhyde l'acétaldéhyde, etc..; comme oxyaldéhyde, on utilise l'aldol., l'aldéhyde de glycérine ou des produits similaires et comme cétone le méthyléthylcétone, le diéthylcétone, l'acétylcarbinol. le mésityloxyde, le pharon. 1?acétone etc..
La condensation se fait avantageusement en solution aqueuse en ajoutant des matières appropriées influençant la condensation telles que des oxydes. hydroxydes ou carbonates alcalins. des alcalino-terreux. du magnésium et de 1' ammonium. des bases organiques telles que 1'éthanolamine, 1'anilline. la quinoline, etc.., des sels de bases fortes avec des acides faibles tels que le glycocollate de sodium,,, le taurinate de sodium. le triphosphate de potassium, etc..
L'addition des matières de concentration au mélange de réaction se fait avantageusement de façon qu9une réaction faiblement alcaline soit maintenue dans le mélange de réaction. Les températures de réactions sont maintenues entre 30 et 100 ou plus; on peut éventuellement travailler sous pression élevée pour éviter des pertes.
Les quantités des aldéhydes peuvent être en proportion équivalente aux quantités des oxyaldéhydes ou des cétones; toutefois,. la pré-
<Desc/Clms Page number 2>
sence en excès d'un des constituants de la réactions spécialement des aldéhydes, donne des avantages.
Après la condensation. les résidus non solubles sont séparés par :filtration; après quoi. se fait la séparation des quantités des produits non entrés en réaction, par exemple par distillation à pression ordinaire ou sous vide. procédé par lequel on enlève simultanément le solvant, totalement ou en partie
Les composés contenant des groupes libres d'aldéhydes ou de cétones contenus dans les produits de condensation sont transformés par de 1' ammoniaque, par des produits aminés,par le bisulfite de sodium, le bisulfi- te d'éthanolamine, etc.. en produits d'addition correspondantso
Les deux traitements, la distillation ainsi que la réaction d' addition peuvent être effectués dans le même appareil.
Les produits de condensation peuvent être transformés en ester par des acides, par exemple par 1'acide adipique. phtalique. etcaoo
On ajoute avantageusement au produit de condensation à froid, des acides tels que l'acide phosphorique. borique, salicylique, adipique. etc.. portant ainsi lucidité à une valeur de ph comprise entre 4 et 6. Par ce fait. les produits de condensation deviennent plus aptes pour le traitement des maladies de la peau. L'emploi des sels acides à la place des acides est aussi possible.
Pour augmenter 1?effet du soulagement dans 1?un ou 1-'autre sens on peut ajouter au produit de condensation d'autres matières telles que 1' iode. le chlorocrésol l'acide salicylique. la résorcine,,, le rivanol. etc.. et en utilisant des pommades de 1?oxyde de zinc,,, de 1'acide borique, etc..
L'emploi des produits de condensation se fait sous cette forme ou avantageusement après l'addition d'une certaine quantité de solvants tels que l'eau.\) l'alcool etc..
On peut les mélanger ou émulsionner avec des matières grasses, des huiles, des cires, des alcools supérieurs ou des matières provoquant un épaississement telles que le polyacrylate de sodium, la tylose,, des sels d9acide de sulfu- re de salicyle, etc..ou on peut les utiliser sous forme de pâte pu de crème.
Ces produits de condensation montrent des propriétés fortement germicides mais pas des effets hémolytiques.
Par exemple une solution de 50% ne montre aucune hémolyse ou coagulation de sang. au contraire d9une solution de sagrotane à 2% qui montre un effet hémolytique très accentué. Il faut mentionner qu'une solution de 15% des produits de condensation suivant les revendications est d'une efficacité égale à une solution de sagrotane à 2% contre le staphylocoque doré hémolytique. les streptocoque hémolytiques et les bacilles de diphtérie. L'effet toxique des produits de condensation est diminué par la séparation ou 1'élimination des groupes réactifs d'aldéhyde ou de cétone à un degré tel que ces produits sont utilisables pour un traitement intraveineux en des concentrations à réaction encore germicides. Par ce fait. un large champ d'emploi est ouvert.
Ces effets désinfectants ne se limitent pas aux bactéries,, les "fungus" sont également anéantis, de sorte qu'on peut combattre avec ces produits des maladies provoquées par des "fungus", telles que 1'épidermophytie. la maladie Wolf-kaufman des mineurs, des dartres, etc.. des plaies inflammatoires ou la peau enflammée,, en particulier les brûlures de soleil. les piqûres d'insectes.
On peut considérer comme avantage dans le traitement avec ce
<Desc/Clms Page number 3>
produit la diminution rapide de la douleur et des démangeaisons provoquées évidemment par un effet analgétique.
L'effet germicide simultané, outre qu'il supprime l'irritation de la peau, a des succès de guérison rapide parmi les maladies nombreuses de la peau.
Exemple 1 :
100 parties d'aldol sont condensées avec 40 parties de formaldéhyde (36%') et 100 parties de lait de chaux,, composéde 30 parties de chaux vive et de
70 parties d'eau à la température de 50 C, sous agitation très poussée. le lait de-chaux ayant été ajouté par petites portions durant 3 heures. Les produits insolubles sont filtrés après la condensation et 40 parties de formaldéhyde et 200 parties deau sont éliminées par distillation. Après le refroidissement., on ajoute 150 parties de bisulfate de sodium. On obtient environ 450 parties du produit de condensation dissous dans l'eau.
100 parties du produit de condensation et 5 parties diacide adipique sont dissoutes dans 200 parties d'eau et sont appliquées sur les pieds nettoyés et séchés qui sont attaqués par la maladie des "fungus", après quoi on laisse sécher.
La maladie disparaît après quelques répétitions de ce traitement.
10 parties du produit de condensation sont mélangées avec 5 parties de ty- lose, 100 parties d'eau et 30 parties d'oxyde polyéthylénique et appliquées à des endroits de brûlure de soleil. Les démangeaisons disparaissent complè- tement en peu de temps sans qu'il y ait formation de cloques. mais la peau desséchée est un peu durcie et se détache après quelques jours.
100 parties du produit de condensation sont mélangées avec 500 parties d' eau. Des souris blanches préablement infectées par des streptocoques ont été soumises à un traitement intraveineux par 0,3 cm3 de cette solution.
Des animaux non infectés ont supportés cette quantité sans exception. Les animaux infectés mais non traités,. périssaient sans exception. tandis que
80% des animaux traités restèrent en vie.
Exemple 2 s 72 parties de diéthylcétone sont agitées avec 450 parties de formaldéhyde à une température de 70 à 90 , On ajoute lentement 20 parties d'éthanola- mine.. en maintenant toujours une réaction alcaline. Après refroidissement de 4 heuresp on ajoute 52 parties de bisulfate de sodium. Au produit de condensation ainsi forme, on ajoute 25 parties de polyacrylate de sodium et 30 parties d'alcool dodécylique. formant ainsi une masse épaisse et crémeuse. Cette masse est appliquée sur les parties de la peau attaquées par 1' épidermophytie. dont la guérison est ainsi rapidement obtenue.
La crème appliquée pour les piqûres d'insectes fait disparaître les démangeaisons immédiatement.
Exemple 3 50 parties du produit de condensation de l'exemple 1 sont chauffées avec 10 parties diacide borique a la température de 120 à 140 C et le produit ainsi formé est mélangé avec du cogasinesulfate de sodium et 20 parties de vaseline. Il se forme une pommade bien stable, qui peut servir d'une façon excellente pour le traitement d'abcès purulent,, de la furonculose,,, de l'eczéma et de maladies similaires.

PROCESS FOR OBTAINING A GERMICIDAL AND SKIN HARDENING PRODUCT.
The use of aldehydes especially formaldehyde as a disinfectant is well known, but these substances have unpleasant effects since they strongly attack the skin, in particular mucous membranes and injured parts of the skin.
It has been found that the condensation products of aldehydes, especially formaldehyde with oxyaldehydes or ketones do not show these unpleasant side effects, if the materials not participating in the condensation reaction are separated after the condensation or are combined by the condensation. addition of materials reacting with the group of aldehydes or ketones.
The aldehydes to be employed are formaldehyde, acetaldehyde, etc .; as oxyaldehyde, aldol., glycerin aldehyde or similar products are used and as ketone methyl ethyl ketone, diethyl ketone, acetylcarbinol. mesityloxide, pharon. 1? Acetone etc.
The condensation is advantageously carried out in aqueous solution by adding suitable materials influencing the condensation such as oxides. alkali hydroxides or carbonates. alkaline earths. magnesium and ammonium. organic bases such as ethanolamine, anillin. quinoline, etc., salts of strong bases with weak acids such as sodium glycocollate ,,, sodium taurinate. potassium triphosphate, etc.
The addition of the concentrating materials to the reaction mixture is advantageously done so that a weakly alkaline reaction is maintained in the reaction mixture. Reaction temperatures are maintained between 30 and 100 or more; one can optionally work under high pressure to avoid losses.
The amounts of the aldehydes may be in a proportion equivalent to the amounts of the oxyaldehydes or of the ketones; however,. the pre-
<Desc / Clms Page number 2>
An excess of one of the reaction constituents, especially aldehydes, gives advantages.
After condensation. insoluble residues are separated by: filtration; after what. the quantities of products not reacted are separated, for example by distillation at ordinary pressure or under vacuum. process by which the solvent is removed simultaneously, in whole or in part
Compounds containing free groups of aldehydes or ketones contained in the condensation products are converted by ammonia, by amine products, by sodium bisulfite, ethanolamine bisulfite, etc. to products. corresponding addition
The two treatments, the distillation as well as the addition reaction can be carried out in the same apparatus.
The condensation products can be converted into an ester by acids, for example by adipic acid. phthalic. etcaoo
Acids such as phosphoric acid are advantageously added to the product of cold condensation. boric, salicylic, adipic. etc. .. thus bringing lucidity to a ph value between 4 and 6. By this fact. the condensation products become more suitable for the treatment of skin diseases. The use of acid salts instead of acids is also possible.
To increase the relief effect in either direction, other materials such as iodine can be added to the condensation product. chlorocresol salicylic acid. resorcinol ,,, rivanol. etc. and using ointments of zinc oxide ,,, boric acid, etc.
The use of the condensation products is done in this form or advantageously after the addition of a certain quantity of solvents such as water. \) Alcohol, etc.
They can be mixed or emulsified with fats, oils, waxes, higher alcohols or thickening materials such as sodium polyacrylate, tylose, salts of salicyl sulfide acid, etc. or they can be used as a paste or cream.
These condensation products show strong germicidal properties but not hemolytic effects.
For example a 50% solution shows no hemolysis or blood coagulation. on the contrary of a 2% sagrotane solution which shows a very marked hemolytic effect. It should be mentioned that a 15% solution of the condensation products according to the claims is of equal effectiveness to a 2% solution of sagrotane against hemolytic Staphylococcus aureus. hemolytic streptococci and diphtheria bacilli. The toxic effect of the condensation products is diminished by the separation or removal of reactive aldehyde or ketone groups to such an extent that these products are useful for intravenous treatment in still germicidal reacting concentrations. By the fact. a wide field of employment is open.
These disinfectant effects are not limited to bacteria, the "fungi" are also suppressed, so that diseases caused by "fungi" such as epidermophytia can be combated with these products. juvenile Wolf-kaufman disease, scabs, etc. inflammatory wounds or inflamed skin,, especially sunburn. insect bites.
One can consider as advantage in the treatment with this
<Desc / Clms Page number 3>
produces the rapid decrease in pain and itching evidently caused by an analgesic effect.
The simultaneous germicidal effect, besides suppressing skin irritation, has rapid healing successes among many skin diseases.
Example 1:
100 parts of aldol are condensed with 40 parts of formaldehyde (36% ') and 100 parts of milk of lime, composed of 30 parts of quicklime and
70 parts of water at a temperature of 50 C, with very thorough stirring. the milk of lime having been added in small portions for 3 hours. The insoluble products are filtered off after the condensation and 40 parts of formaldehyde and 200 parts of water are removed by distillation. After cooling, 150 parts of sodium bisulfate are added. About 450 parts of the condensation product dissolved in water are obtained.
100 parts of the condensation product and 5 parts adipic acid are dissolved in 200 parts of water and are applied to the cleaned and dried feet which are attacked by the "fungus" disease, after which it is allowed to dry.
The disease disappears after a few repetitions of this treatment.
10 parts of the condensation product is mixed with 5 parts of ty- lose, 100 parts of water and 30 parts of polyethylene oxide and applied to sunburn spots. The itching disappears completely in a short time without blistering. but the parched skin is a little hardened and comes off after a few days.
100 parts of the condensation product are mixed with 500 parts of water. White mice previously infected with streptococci were subjected to intravenous treatment with 0.3 cm3 of this solution.
Uninfected animals endured this amount without exception. Animals infected but not treated. perished without exception. while
80% of the animals treated remained alive.
Example 2 72 parts of diethyl ketone are stirred with 450 parts of formaldehyde at a temperature of 70 to 90. 20 parts of ethanolamine are added slowly while still maintaining an alkaline reaction. After cooling for 4 hours, 52 parts of sodium bisulfate are added. To the condensation product thus formed, 25 parts of sodium polyacrylate and 30 parts of dodecyl alcohol are added. thus forming a thick and creamy mass. This mass is applied to the parts of the skin attacked by epidermophytia. whose cure is thus quickly obtained.
The cream applied for insect bites makes the itching disappear immediately.
Example 3 50 parts of the condensation product of Example 1 are heated with 10 parts of boric diacid at a temperature of 120 to 140 C and the product thus formed is mixed with sodium cogasinesulphate and 20 parts of petrolatum. A very stable ointment is formed which can be used excellently for the treatment of purulent abscess, furunculosis, eczema and similar diseases.
