DESCRIZIONE DESCRIPTION
Annessa a domanda di brevetto per INVENZIONE INDUSTRIALE avente per titolo Attached to a patent application for INDUSTRIAL INVENTION having the title
"COMPOSIZIONE PER CREMA BASE COSMETICA E SUO "COMPOSITION FOR COSMETIC BASE CREAM AND ITS
PROCEDIMENTO DI PREPARAZIONE" PREPARATION PROCEDURE "
La presente invenzione ha per oggetto una composizione per crema base cosmetica. Essa riguarda inoltre un procedimento di preparazione della suddetta crema base. The present invention relates to a composition for cosmetic base cream. It also relates to a process for preparing the aforementioned base cream.
Per crema base di cosmetico si intende un eccipiente, cioè qualsiasi sostanza inerte che venga incorporata nel cosmetico senza esserne il principio attivo. L'inventore ha trovato che gli attuali eccipienti, per come vengono industrialmente emulsionati, solitamente in una fase sola, hanno una bassa curva di saturazione ed un rilascio troppo rapido dei principi attivi incorporati nel cosmetico. By cosmetic base cream we mean an excipient, that is any inert substance that is incorporated into the cosmetic without being its active ingredient. The inventor has found that the current excipients, as they are industrially emulsified, usually in a single phase, have a low saturation curve and a too rapid release of the active ingredients incorporated in the cosmetic.
Gli ingredienti previsti nella crema base secondo l'invenzione sono: pectina, glicol propilenico, glicerina, petrolato o vaselina. The ingredients provided in the base cream according to the invention are: pectin, propylene glycol, glycerin, petrolatum or petroleum jelly.
Il brevetto statunitense N. 6,712,805 prevede che varie composizioni cosmetiche siano incorporate nella pelle con un metodo e un'apparecchiatura che fornisce suoni a determinate frequenze per l'invio transdermico di una sospensione di microparticelle contenenti sostanze medicinali o cosmetici. US Patent No. 6,712,805 provides that various cosmetic compositions are incorporated into the skin by a method and apparatus that provides sounds at certain frequencies for transdermal delivery of a suspension of microparticles containing medicinal or cosmetic substances.
Una di queste varie composizioni comprende, come basi di unguento petrolato, petrolato idrofilo, petrolato bianco, come agente addensante pectina, e come altri agenti, glicerina e glicol propilenico. One of these various compositions includes, as petrolatum ointment bases, hydrophilic petrolatum, white petrolatum, pectin thickening agent, and as other agents, glycerin and propylene glycol.
Tuttavia, la caratteristica della presente invenzione non risiede nell'uso combinato degli ingredienti sopra citati, ma nella loro selezione in percentuali ben precise e in un particolare procedimento di preparazione allo scopo di fornire un eccipiente con altissima curva di saturazione e lento rilascio dei principi attivi, risultati questi finora non ottenuti, per quanto ne sappia l'inventore. Particolarmente, il glicol propilenico stabilisce le condizioni ideali per incorporare i principi attivi di derivazione vegetale. However, the characteristic of the present invention does not lie in the combined use of the above-mentioned ingredients, but in their selection in very precise percentages and in a particular preparation process in order to provide an excipient with a very high saturation curve and slow release of the active ingredients. , these results have not been obtained so far, as far as the inventor knows. In particular, propylene glycol establishes the ideal conditions for incorporating the active ingredients of plant origin.
Secondo un primo aspetto dell'invenzione, viene fornita una selezione di sostanze che possono essere mescolate per ottenere una crema base di cosmetico, unendo come agente addensante pectina, come solvente e tensioattivo glicol propilenico, come solvente e stabilizzante del volume glicerina, e come regolatore di densità vaselina. According to a first aspect of the invention, a selection of substances is provided which can be mixed to obtain a cosmetic base cream, combining pectin as a thickening agent, propylene glycol as a solvent and surfactant, as a solvent and glycerin volume stabilizer, and as a regulator. of vaseline density.
Preferibilmente, la pectina è pectina vegetale, la glicerina è glicerina purissima e la vaselina è vaselina alba filante e vaselina bianca. Preferably, pectin is vegetable pectin, glycerin is pure glycerin and petroleum jelly is stringy white petroleum jelly and white petroleum jelly.
In una rivendicazione dipendente, sono fornite le percentuali più vantaggiose per gli scopi dell'invenzione, e quella particolarmente preferita. Conformemente ad un secondo aspetto dell'invenzione, viene fornito un procedimento comprendente, nella forma di esecuzione preferita, un numero elevato di passi, che si sono dimostrati utili per ottenere la crema base, vale a dire i seguenti: In a dependent claim, the most advantageous percentages for the purposes of the invention, and the particularly preferred one, are provided. According to a second aspect of the invention, a process is provided comprising, in the preferred embodiment, a large number of steps, which have proved useful for obtaining the base cream, namely the following:
- miscelazione di glicerina e pectina; - mixing of glycerin and pectin;
- emulsione delle stesse; - emulsion of the same;
- prima aggiunta di glicol propilenico e mescolamento; - first addition of propylene glycol and mixing;
- mantenimento a temperatura e sedimentazione; - maintenance at temperature and sedimentation;
- aggiunta di un primo tipo di vaselina e incorporazione; - addition of a first type of petroleum jelly and incorporation;
- aggiunta di un secondo tipo di vaselina e incorporazione; - addition of a second type of petroleum jelly and incorporation;
- seconda aggiunta di glicol propilenico e incorporazione molto lenta; - second addition of propylene glycol and very slow incorporation;
- aggiunta graduale di pectina; - gradual addition of pectin;
- emulsione di tutte le sostanze presenti e aggiunta graduale di pectina; - terza aggiunta molto lenta di glicol propilenico; - emulsion of all the substances present and gradual addition of pectin; - third very slow addition of propylene glycol;
- quarta aggiunta di glicol propilenico e lenta miscelazione al centro; - fourth addition of propylene glycol and slow mixing in the center;
- ulteriore incorporazione di pectina, ed emulsione; - further incorporation of pectin, and emulsion;
ancora un'aggiunta molto lenta di pectina ed emulsione, con miscelazione centrale molto lenta; still a very slow addition of pectin and emulsion, with very slow central mixing;
- a questo punto, ulteriore agitazione lenta alla velocità più bassa consentita del macchinario usato per la preparazione; e - at this point, further slow stirring at the lowest allowed speed of the machinery used for preparation; And
- almeno tre ore di posa. - at least three hours of laying.
Il prodotto finale è una valida crema base a lento rilascio come eccipiente, ma anche un discreto idratante, soprattutto per quel tipo di pelle soggetto a cheratosi senile, che si manifesta in forma di macula di colore brunastro. La conservazione del prodotto è sottovuoto. The final product is a valid slow-release base cream as an excipient, but also a decent moisturizer, especially for that type of skin prone to senile keratosis, which manifests itself in the form of a brownish macula. The product is stored under vacuum.
Il compito tecnico sopra precisato e gli scopi specificati sono sostanzialmente raggiunti da una composizione per crema base cosmetica e da un procedimento di preparazione della suddetta crema base. The technical task specified above and the purposes specified are substantially achieved by a composition for a cosmetic base cream and by a process for preparing the aforementioned base cream.
Secondo il procedimento di preparazione, realizzabile industrialmente aumentandone semplicemente le dosi, circa 250 g di glicerina purissima F.U. e 100 g di pectina vegetale sono mescolati ed emulsionati insieme. L'emulsione è da intendersi come temporanea, visto che per ottenere uno stato di emulsione stabile bisognerebbe aggiungere granulato di lecitina di soia come emulsionante. According to the preparation procedure, industrially achievable by simply increasing the doses, about 250 g of pure glycerin F.U. and 100 g of vegetable pectin are mixed and emulsified together. The emulsion is intended as temporary, since in order to obtain a stable emulsion state, soy lecithin granules should be added as an emulsifier.
A titolo di esempio, il miscelatore In line Silverson (SILVERSON MACHINES LTD di Waterside, Chesham Bucks, Inghilterra) può emulsionare ed omogeneizzare, migliorando la qualità e la consistenza di questa crema. As an example, the Silverson In line blender (SILVERSON MACHINES LTD of Waterside, Chesham Bucks, England) can emulsify and homogenize, improving the quality and consistency of this cream.
Ad essi vengono aggiunti circa 103 g di glicol propilenico con successiva miscelazione. Il miscuglio viene fatto riposare per almeno 24 ore ad una temperatura di 4°C, permettendo la sedimentazione. Successivamente vengono aggiunti ed incorporati 30 g di vaselina bianca F.U. To them about 103 g of propylene glycol are added with subsequent mixing. The mixture is left to rest for at least 24 hours at a temperature of 4 ° C, allowing sedimentation. Then 30 g of white F.U. Vaseline are added and incorporated.
Vengono quindi aggiunti 40 g di vaselina alba filante ed incorporati dolcemente. Sono utilizzate queste due qualità di vaselina perché hanno una densità diversa, e ciò conferisce una maggiore stabilità all'emulsione . Quindi vengono aggiunti circa 103 g di glicol propilenico ed incorporati molto lentamente. L'aggiunta graduale di glicol propilenico, che è comunemente noto come solvente, serve nella presente invenzione a mantenere in soluzione il preparato, ma soprattutto ad abbassare la tensione superficiale dello stesso. Il glicol propilenico deve essere aggiunto gradualmente perché in tal modo abbassa con maggiore efficacia la tensione superficiale del preparato. 40 g of vaseline alba stringante are then added and gently incorporated. These two qualities of petroleum jelly are used because they have a different density, and this gives greater stability to the emulsion. Then about 103 g of propylene glycol are added and incorporated very slowly. The gradual addition of propylene glycol, which is commonly known as a solvent, serves in the present invention to keep the preparation in solution, but above all to lower its surface tension. Propylene glycol must be added gradually because in this way it lowers the surface tension of the preparation more effectively.
Sono poi aggiunti gradualmente 150 g di pectina. Viene eseguita nuovamente un'emulsione temporanea. 150 g of pectin are then gradually added. A temporary emulsion is performed again.
Avvenuta l'emulsione temporanea, si aggiungono a poco a poco altri 100 g di pectina vegetale. Si unisce ad esso molto lentamente circa 52 g di glicol propilenico. Quindi si aggiungono altri 52 g circa di glicol propilenico, si incorporano nuovamente 50 g di pectina e si emulsiona temporaneamente. Molto lentamente, per l'ultima volta, si aggiungono 25 g di pectina vegetale e si emulsiona a poco a poco, miscelando alla velocità più bassa consentita dal miscelatore. Queste ultime aggiunte di pectina servono per la stabilità dell'emulsione. Once the temporary emulsion has taken place, gradually add another 100 g of vegetable pectin. About 52 g of propylene glycol is added to it very slowly. Then about another 52 g of propylene glycol are added, 50 g of pectin are incorporated again and temporarily emulsified. Very slowly, for the last time, 25 g of vegetable pectin are added and it is gradually emulsified, mixing at the lowest speed allowed by the mixer. These last additions of pectin serve for the stability of the emulsion.
La composizione di crema base secondo la presente invenzione ha le seguenti percentuali: glicerina 23,8%, pectina 40,5%, glicol propilenico 29,0% e vaselina 6,7%. The basic cream composition according to the present invention has the following percentages: glycerin 23.8%, pectin 40.5%, propylene glycol 29.0% and petroleum jelly 6.7%.
La crema base così ottenuta può costituire un ottimo eccipiente con altissima curva di saturazione utilizzabile per molti preparati cosmetici. The base cream thus obtained can constitute an excellent excipient with a very high saturation curve that can be used for many cosmetic preparations.
Questa crema base può ad esempio costituire l'eccipiente per una crema di collagene ed elastina e deve essere conservata in frigorifero. Tuttavia la stessa crema base può essere utilizzata per una composizione descritta in una co-pendente domanda di brevetto dello stesso inventore, grazie alla quale tale crema non richiede una conservazione refrigerata. This base cream can, for example, be the excipient for a collagen and elastin cream and must be kept in the refrigerator. However, the same basic cream can be used for a composition described in a co-pending patent application of the same inventor, thanks to which this cream does not require refrigerated storage.
Tuttavia tali percentuali possono variare in più o in meno del 10% senza allontanarsi dall'ambito di protezione della composizione di crema secondo la presente invenzione. However, these percentages may vary by more or less than 10% without departing from the scope of the cream composition according to the present invention.
