PROCEDE DE FABRICATION D'EXTRAIT CELLULAIRE HYDROSOLUBLE
D'EMBRYONS D'OEUF ET PRODUIT OBTENU
La présente invention a pour objet un procédé de fabrication d'extrait cellulaire hydrosoluble d'embryons d'oeuf et le produit obtenu.PROCESS FOR MANUFACTURING WATER-SOLUBLE CELL EXTRACT
EGG EMBRYOS AND PRODUCT OBTAINED
The subject of the present invention is a process for manufacturing a water-soluble cellular extract from egg embryos and the product obtained.
Le produit obtenu est destiné à être incorporé à des compositions pharmaceutiques ou cosmétologiques notamment dans des préparations pour traitement des brûlures et plaies, ou des préparations ralentissant le vieillissement dermique, ou nourrissant le derme, par exemple destinées à être utilisées après exposition au soleil.The product obtained is intended to be incorporated into pharmaceutical or cosmetic compositions in particular in preparations for the treatment of burns and wounds, or preparations slowing down dermal aging, or nourishing the dermis, for example intended for use after exposure to the sun.
De nombreuses préparations cosmétologiques décrites dans les formulaires de cosmétologie contiennent de la lécithine comme émulsionnant et co-émulsionnant, de l'huile d'oeuf riche en acide oléique et linoléique, ou du jaune d'oeuf, introduit en particulier dans les shampoings et les crèmes, plus dans un but de marketing que scientifique. Aucune de ces préparations n'est à même de tirer parti des propriétés régénératrices et cicatrisantes de l'embryon d'oeuf.Many cosmetic preparations described in cosmetology forms contain lecithin as an emulsifier and co-emulsifier, egg oil rich in oleic and linoleic acid, or egg yolk, introduced in particular in shampoos and creams, more for marketing than scientific. None of these preparations is able to take advantage of the regenerative and healing properties of the egg embryo.
L'extrait cellulaire d'oeuf obtenu par le procédé suivant la présente invention est remarquable en ce qu 'il présente des propriétés trophiques, régénératrices et cicatrisantes, ainsi qu'une très bonne tolérance par le derme.The egg cell extract obtained by the process according to the present invention is remarkable in that it has trophic, regenerative and healing properties, as well as very good tolerance by the dermis.
Le procédé suivant l'invention consiste à traiter de la poudre pasteurisée de jaune d'oeuf successivement au moyen de plusieurs solvants organiques tels que acétone et éthanol, le produit brut obtenu étant recueilli, mis en solution aqueuse, celle-ci étant soumise à une diafiltration sur membrane poreuse calibrée présentant un seuil de rétention de substances dont le poids moléculaire est égal ou inférieur à 100 000. The process according to the invention consists in treating pasteurized egg yolk powder successively by means of several organic solvents such as acetone and ethanol, the crude product obtained being collected, put into aqueous solution, the latter being subjected to a diafiltration on a calibrated porous membrane having a retention threshold for substances whose molecular weight is equal to or less than 100,000.
D'autres caractéristiques ressortent de la description détaillée suivante, qui concerne un exemple non limitatif d'une des formes de réalisation.Other characteristics will emerge from the following detailed description, which relates to a nonlimiting example of one of the embodiments.
Le produit selon la présente invention est obtenu en appliquant le procédé ci-après
Tout d'abord, 100 grammes de poudre de jaune d'oeuf pasteurisé sont mis en suspension dans 300 ml d'acétone froid. Le mélange est agité vigoureusement pendant 3 heures à 3500 tours/minute, puis la suspension est filtrée sur verre fritté et l'on recueille une poudre jaune que l'on essore rapidement.The product according to the present invention is obtained by applying the process below
First, 100 grams of pasteurized egg yolk powder is suspended in 300 ml of cold acetone. The mixture is vigorously stirred for 3 hours at 3500 rpm, then the suspension is filtered through sintered glass and a yellow powder is collected which is wrung quickly.
La poudre obtenue est mise en suspension dans 300 ml d'éthanol froid et agitée vigoureusement pendant 3 heures à 1500 tours/ minute, puis la suspension est filtrée sur verre fritté et l'on recueille d'une part la solution éthanolique, et d'autre part une poudre qui est mise en suspension dans 150 ml d'acétone froid.The powder obtained is suspended in 300 ml of cold ethanol and vigorously stirred for 3 hours at 1500 revolutions / minute, then the suspension is filtered on sintered glass and the ethanolic solution is collected on the one hand, and on the other hand a powder which is suspended in 150 ml of cold acetone.
Le mélange est agité vigoureusement pendant 2 heures à 1500 tours/minute, puis la suspension est filtrée sur verre fritté et l'on recueille la solution acétonique, et une poudre qui est essorée puis sèchée à température ambiante sous vide pendant 48 heures.The mixture is vigorously stirred for 2 hours at 1500 revolutions / minute, then the suspension is filtered through sintered glass and the acetone solution is collected, and a powder which is wrung and then dried at room temperature under vacuum for 48 hours.
On obtient finalement 40 grammes d'une poudre blanc-jaunâtre, qui sont mis en solution dans de l'eau distillée et filtrée à 0,22 nìicron et la solution est maintenue sous agitation à 250C pendant 4 heures puis centrifugée à 9000 g. La solution est récupérée et passée en totalité dans un appareil à diafiltrer équipé de membranes poreuses dont le seuil de rétention est de 100 000. La solution diafiltrée est récupérée puis l'on introduit 0,05 gramme de conservateur bactéricide pour 100 grammes de solution.40 grams of a yellowish-white powder are finally obtained, which are dissolved in distilled water and filtered at 0.22 nm and the solution is stirred at 250C for 4 hours and then centrifuged at 9000 g. The solution is recovered and passed entirely through a diafiltration device equipped with porous membranes, the retention threshold of which is 100,000. The diafiltered solution is recovered and then 0.05 grams of bactericidal preservative are introduced per 100 grams of solution.
Les quantités, durées de traitement et poids moléculaire indiqués ci-dessus sont donnés à titre indicatif et peuvent varier dans des proportions assez importantes.The quantities, duration of treatment and molecular weight indicated above are given as an indication and can vary within fairly large proportions.
Par ailleurs, les solutions acétonique et éthanolique sont mélangées puis distillées sous vide à 400C, ce qui permet d'obtenir 58 grammes d'huile d'oeuf.Furthermore, the acetone and ethanolic solutions are mixed and then distilled under vacuum at 400C, which allows to obtain 58 grams of egg oil.
L'extrait cellulaire hydrosoluble d'embryon d'oeuf est limpide, très légèrement jaune pale. Il a un ph de 6, une densité de 1,002 et contient en particulier les acides aminés suivants
Alanine, Arginine, Acide aspartique, Cystine, Acide glutamique,
Glycine, Histidine, Isoleucine, Leucine, Lysine, Méthionine,
Phénylanine, Proline, Serine, Tréonine, Tryptophane, Tyrosine, et Valine. The water-soluble cell extract from the egg embryo is clear, very slightly pale yellow. It has a pH of 6, a density of 1.002 and contains in particular the following amino acids
Alanine, Arginine, Aspartic acid, Cystine, Glutamic acid,
Glycine, Histidine, Isoleucine, Leucine, Lysine, Methionine,
Phenylanine, Proline, Serine, Treonine, Tryptophan, Tyrosine, and Valine.
Le principe actif peut être incorporé à des excipients habituellement utilisés dans les compositions cosmétologiques et pharmaceutiques, les véhicules aqueux ou non, les corps gras d'origine animale ou végétale, les dérivés paraffiniques, les glycols, les divers agents mouillants, dispersants ou émulsifiants, les conservateurs.The active principle can be incorporated into excipients usually used in cosmetic and pharmaceutical compositions, aqueous or non-aqueous vehicles, fatty substances of animal or vegetable origin, paraffinic derivatives, glycols, various wetting agents, dispersants or emulsifiers, conservatives.
Grâce à sa remarquable efficacité, le produit qui vient d'être décrit se prête particulièrement bien à la confection de spécialités cosmétologiques ou pharmacologiques en étant utilisé dans une proportion de 10 à 30 % dans les solutions crèmes, pommades, lotions, gouttes ou autres.Thanks to its remarkable effectiveness, the product which has just been described lends itself particularly well to the preparation of cosmetological or pharmacological specialties by being used in a proportion of 10 to 30% in creams, ointments, lotions, drops or other solutions.
Le positionnement des divers éléments constitutifs donnent à ce produit un maximum d'effets utiles qui n'avaient pas été obtenus à ce jour par des produits similaires. The positioning of the various constituent elements gives this product a maximum of useful effects which had not been obtained to date by similar products.
