a corredo di una domanda di brevetto per invenzione industriale avente per titolo: accompanying a patent application for an industrial invention entitled:
“USO DI GLUCIDI PER RENDERE LISCIO IL CAPELLO RICCIO, CRESPO OD ONDULATO” "USE OF GLUCIDES TO MAKE CURLY, CREAMY OR WAVY HAIR SMOOTH"
TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
La presente domanda di brevetto per invenzione industriale ha per oggetto l’uso dei glucidi per rendere liscio il capello riccio, crespo od ondulato . The present patent application for industrial invention relates to the use of carbohydrates to make curly, frizzy or wavy hair smooth.
Il Problema attuale è che pur essendo già note sostanze chimiche in grado di rendere lisci i capelli della specie umana che siano di aspetto crespo od ondulato, tali sostanze presentano problemi di elevata aggressività verso il capello stesso (es aldeide formica, sodio idrossido, composti solforati etc.). The current problem is that although chemical substances capable of making hair of the human species smooth that are of a frizzy or wavy appearance are already known, these substances present problems of high aggressiveness towards the hair itself (eg formic aldehyde, sodium hydroxide, sulfur compounds etc.).
Il capello della specie umana si distingue in due tipologie: The hair of the human species is divided into two types:
- La prima tipologia di capello, cosiddetto “afro” (capello avente un diametro di 70-100 microns), di colore generalmente scuro, che ha la caratteristica di essere arricciato più o meno marcatamente a seconda della quantità di gruppi di solfuro tra le catene proteiche costituenti la cheratina (proteina di base del capello umano); - The first type of hair, so-called "afro" (hair having a diameter of 70-100 microns), generally dark in color, which has the characteristic of being curled more or less markedly depending on the amount of sulphide groups between the chains protein constituents of keratin (basic protein of human hair);
- La seconda tipologia di capello, cosiddetto “caucasico” (capello avente un diametro di 60-80 microns), di colore scuro o chiaro, che ha la caratteristica di essere arricciato in maniera meno marcata rispetto al tipo “afro”, a causa della minore quantità di ponti di solfuro presenti nella struttura della propria cheratina. - The second type of hair, so-called "Caucasian" (hair having a diameter of 60-80 microns), of dark or light color, which has the characteristic of being curled less markedly than the "afro" type, due to the lower quantity of sulphide bridges present in the structure of one's keratin.
Scopo della presente invenzione è quello di rendere liscio il capello riccio, crespo od ondulato utilizzando sostanze organiche appartenenti alla famiglia dei glucidi. The purpose of the present invention is to make curly, frizzy or wavy hair smooth by using organic substances belonging to the family of carbohydrates.
Questi scopi sono raggiunti in accordo all’invenzione, con le caratteristiche elencate nell’annessa rivendicazione indipendente 1. These purposes are achieved in accordance with the invention, with the characteristics listed in the attached independent claim 1.
Realizzazioni vantaggiose appaiono dalle rivendicazioni dipendenti. Advantageous embodiments appear from the dependent claims.
Gli studi eseguiti sulle sostanze chimiche già in uso nel settore cosmetico, e le prove eseguite sui capelli, hanno portato alla scoperta un diverso uso delle sostanze organiche appartenenti alla famiglia dei glucidi, il quale consente l’eliminazione delle tipiche curve che caratterizzano i capelli ricci, crespi od ondulati. The studies carried out on the chemicals already in use in the cosmetic sector, and the tests carried out on the hair, have led to the discovery of a different use of organic substances belonging to the family of carbohydrates, which allows the elimination of the typical curves that characterize curly hair , frizzy or wavy.
Sono ben note le reazioni che avvengono tra i glucidi e le proteine nel caso di esposizione al calore quale ad esempio la reazione di Maillard (con conseguente riarrangiamento di Amadori/Heyns) e la connessa reazione di Strecker. The reactions that occur between carbohydrates and proteins in the case of heat exposure are well known, such as the Maillard reaction (with consequent Amadori / Heyns rearrangement) and the related Strecker reaction.
Il meccanismo di base di dette reazioni chimiche è illustrato nella figura 1. The basic mechanism of these chemical reactions is illustrated in Figure 1.
Queste reazioni generano una complessa serie di fenomeni che avviene in sostanza a seguito dell'interazione tra i gruppi aldeidici e chetonici dei glucidi e gli aminoacidi aventi gruppi amminici liberi (-NH2), in presenza di elevata temperatura e adeguata concentrazione di idrogenioni (H<+>) (pH). These reactions generate a complex series of phenomena which essentially occurs as a result of the interaction between the aldehyde and ketone groups of the carbohydrates and the amino acids having free amino groups (-NH2), in the presence of high temperature and adequate concentration of hydrogen ions (H < +>) (pH).
La reazione può essere suddivisa in tre fasi principali. La prima fase è caratterizzata dalla formazione di una base di Schiff tramite reazione del carbonio carbonilico dello zucchero con un gruppo amminico di un amminoacido, con la conseguente formazione di una glicosilammina. The reaction can be divided into three main steps. The first phase is characterized by the formation of a Schiff base by reaction of the carbonyl carbon of the sugar with an amino group of an amino acid, with the consequent formation of a glycosylamine.
Questa successivamente subisce un riarrangiamento dei doppi legami che porta alla formazione di un composto di Amadori o di Heyns a seconda che lo zucchero sia rispettivamente un aldoso o un chetoso. Il riarrangiamento di Amadori-Heyns è catalizzato dagli acidi. This subsequently undergoes a rearrangement of the double bonds which leads to the formation of an Amadori or Heyns compound depending on whether the sugar is respectively an aldose or a ketose. The Amadori-Heyns rearrangement is catalyzed by acids.
Nella seconda fase si possono avere un gran numero di reazioni che sono influenzate da fattori come la temperatura e il pH. I percorsi principali della seconda fase di reazione sono: In the second phase, a large number of reactions can occur which are influenced by factors such as temperature and pH. The main pathways of the second reaction phase are:
1) formazione di composti dicarbonilici: i composti di Amadori possono enolizzare formando composti alfadicarbonilici, i quali a loro volta possono ciclizzare; scindersi; oppure possono reagire con altri composti come gli amminoacidi liberi; 1) formation of dicarbonyl compounds: Amadori compounds can enolize forming alpha-carbonyl compounds, which in turn can cyclize; split up; or they can react with other compounds such as free amino acids;
2) disidratazione drastica di vari composti della prima fase; 2) drastic dehydration of various compounds of the first phase;
3) scissione di vari composti formatisi nella prima fase, la reazione è favorita dalle alte temperature e produce composti carbonilici e dicarbonilici a basso numero di atomi di carbonio come l'aldeide glicerica e piruvica. 3) cleavage of various compounds formed in the first phase, the reaction is favored by high temperatures and produces carbonyl and dicarbonyl compounds with a low number of carbon atoms such as glycerine and pyruvic aldehyde.
Segue una terza fase nella quale si formano le melanoidine, sostanze colorate in giallo-bruno, a contenuto di azoto variabile poiché possono derivare da composti diversi, ad alto peso molecolare ed insolubili. A third phase follows in which melanoidins are formed, yellow-brown colored substances with variable nitrogen content since they can derive from different compounds, with high molecular weight and insoluble.
A questa fase si giunge dopo che le molte specie a basso peso formatesi nelle due fasi precedenti, reagiscono tra loro; ad esempio per condensazione di aldeidi e chetoni. This phase is reached after the many low-weight species formed in the two previous phases react with each other; for example by condensation of aldehydes and ketones.
Orbene, sorprendentemente, è stato scoperto che la reazione di Maillard avviene anche quando si tratta il capello riccio, crespo od ondulato della specie umana, con uno o più glucidi elencati in tabella 1e lo si espone al calore (come ad esempio facendolo passare su di una piastra stira capelli di uso comune in parrucchieria). Surprisingly, it has been discovered that the Maillard reaction also occurs when the curly, frizzy or wavy hair of the human species is treated with one or more carbohydrates listed in table 1 and exposed to heat (such as by passing it over a hair straightener commonly used in hairdressing).
Il risultato che il capello perde il caratteristico aspetto riccio crespo od ondulato e acquisisce un aspetto liscio ed una sfumatura di colore più scura dell’originale ante trattamento. The result is that the hair loses its characteristic frizzy or wavy curly appearance and acquires a smooth appearance and a darker shade of color than the original pre-treatment.
Nella Tabella 1 sono elencati i glucidi ad oggi noti i quali hanno dimostrato di risolvere il problema descritto (e tra queste in particolare il FRUTTOSIO (numero CAS 57-48-7), il GLUCOSIO (numero CAS 50-99-7 ) ed il SACCAROSIO (numero CAS 57-50-1 ) la GLICOLALDEIDE dimero (numero CAS 23147-58-2). Table 1 lists the carbohydrates known to date which have been shown to solve the problem described (and among these in particular FRUCTOSE (CAS number 57-48-7), GLUCOSE (CAS number 50-99-7) and SUCROSE (CAS number 57-50-1) the dimer GLYCOLALDEHYD (CAS number 23147-58-2).
Inoltre sono state sottoposte a prova, in miscela con uno dei glucidi sopra indicati, anche le sostanze indicate nella Tabella 2, di suo comune nel settore cosmetico e comprese nell’elenco allegato alla Decisione n. 1996/335/CE del 08/05/1996 e successive modifiche ed integrazioni. In addition, the substances listed in Table 2, common to you in the cosmetic sector and included in the list attached to Decision no. 1996/335 / EC of 08/05/1996 and subsequent amendments and additions.
Tra tutti i glucidi elencati in tabella 1 è stato scelto di sperimentare in particolare l’uso del FRUTTOSIO (numero CAS 57-48-7) allo scopo di produrre il lisciamento dei capelli crespi ed ondulati. Among all the carbohydrates listed in table 1, it was chosen to experiment in particular with the use of FRUCTOSE (CAS number 57-48-7) in order to smooth frizzy and wavy hair.
Circa le modalità d’uso della sostanza oggetto dell’invenzione sono state eseguite prove consistenti nella dissoluzione in 100 millilitri di acqua acidulata (pH 2,5-5,5) di 30 grammi di Fruttosio. As regards the methods of use of the substance object of the invention, tests were carried out consisting in the dissolution of 30 grams of fructose in 100 milliliters of acidulated water (pH 2.5-5.5).
Più precisamente in rapporto ponderale compreso tra il 5 % ed il 60%. More precisely in a weight ratio between 5% and 60%.
In particolare il capello è stato lavato con shampoo a pH basico (7,5-8,5), dopodiché sullo stesso è stata spalmata detta soluzione di Fruttosio con pennello a setole rigide. In particular, the hair was washed with a basic pH shampoo (7.5-8.5), after which said Fructose solution was spread on it with a rigid bristle brush.
Il capello è stato lasciato a contatto con la sostanza per un tempo di 60 minuti dopodiché è stato asciugato con un asciugacapelli. The hair was left in contact with the substance for 60 minutes, after which it was dried with a hairdryer.
Una volta asciutto il capello è stato sottoposto a stiratura mediante utilizzo di piastra stira capelli, posta alla temperatura di circa 200 gradi centigradi. Once dry, the hair was subjected to straightening using a straightener, placed at a temperature of about 200 degrees centigrade.
Quindi lo stesso è stato sottoposto a successivo lavaggio con shampoo a pH acido (4,5-5,5 circa) e ad asciugatura, con un asciugacapelli. Then the same was subjected to subsequent washing with acid pH shampoo (4.5-5.5 approximately) and drying with a hairdryer.
Al termine del trattamento il capello si è presentato lucido, liscio, morbido al tatto, e con aspetto complessivo particolarmente gradevole. At the end of the treatment the hair was shiny, smooth, soft to the touch, and with a particularly pleasant overall appearance.
Le prove effettuate hanno consentito di verificare lì efficacia del trovato sia su capello naturale che su capello decolorato chimicamente. The tests carried out made it possible to verify the effectiveness of the invention both on natural hair and on chemically bleached hair.
Ulteriori prove sono state eseguite aggiungendo a detta soluzione di Fruttosio una delle sostanze elencate nella tabella 2. Further tests were carried out by adding one of the substances listed in table 2 to said fructose solution.
Ciascuna sostanza è stata provata in miscela con la detta soluzione di Fruttosio aggiungendo a 100 millilitri di questa 10 grammi di una delle sostanze indicate nella tabella 2. Each substance was tested in mixture with the said Fructose solution by adding 10 grams of one of the substances indicated in table 2 to 100 milliliters of this.
Di seguito si riporta una composizione tipo di detta miscela: Below is a typical composition of said mixture:
Esempio 1: Example 1:
Acqua acidulata ……..…………..100 grammi Frutttosio ………………………… 30 grammi Acidulated water …… .. …………. 100 grams Fructtose ………………………… 30 grams

Acqua acidulata ……..…………..100 grammi Frutttosio ………………………… 30 grammi Acido gliossilico ….. …….……… 10 grammi Anche al termine dei trattamenti eseguiti utilizzando le miscele indicate negli esempi 1, 2, 3 e 4 sopra esposti il capello si è presentato lucido, liscio, morbido al tatto, e con aspetto complessivo particolarmente gradevole. Acidulated water …… .. …………. 100 grams Fructtose ………………………… 30 grams Glyoxylic acid… .. ……. ……… 10 grams Even at the end of the treatments performed using the indicated mixtures in examples 1, 2, 3 and 4 shown above, the hair was shiny, smooth, soft to the touch, and with a particularly pleasant overall appearance.
Ulteriori prove sono state eseguite per verificare se l’effetto ottenuto con le soluzioni acquose fosse replicabile anche nel caso in cui queste sostanze facessero parte di una formulazione cosmetica commerciale (e quindi fossero in miscela con altre sostanze di uso comune nel settore cosmetico per la lisciatura dei capelli). Further tests were performed to verify whether the effect obtained with the aqueous solutions was replicable even if these substances were part of a commercial cosmetic formulation (and therefore were mixed with other substances commonly used in the cosmetic sector for smoothing. hair).
E’ stata quindi eseguita un’ulteriore prova addizionando il fruttosio (e miscele tra questo ed il Potassio Ioduro, il Diidrossiacetone, l’Acido gliossilico ed il 2,4 esadienale indicate negli esempi 1, 2, 3 e 4 sopra esposti) con cosmetici reperiti sul mercato e destinati al trattamento dei capelli. A further test was then carried out by adding fructose (and mixtures between this and Potassium Iodide, Dihydroxyacetone, glyoxylic acid and 2,4 hexadienal indicated in examples 1, 2, 3 and 4 above) with cosmetics found on the market and intended for hair treatment.
In particolare è stata eseguita una prova di allisciamento del capello utilizzando la formulazione di un prodotto cosmetico della INOAR Cosmeticos Ltda di San Paolo del Brasile denominato “Tratamento capillar marroquino”. Il prodotto è stato privato del suo ingrediente attivo per l’allisciamento del capello (ovvero aldeide formica). In particular, a hair smoothing test was performed using the formulation of a cosmetic product from INOAR Cosmeticos Ltda of Sao Paulo in Brazil called “Marroquino capillar treatment”. The product has been deprived of its active ingredient for smoothing the hair (or ant aldehyde).
A 100 millilitri di questo cosmetico sono stati aggiunti 10 grammi di Fruttosio e, dopo aver eseguito le stesse operazioni di trattamento del capello già descritte nelle pagine precedenti, sono stati raggiunti gli stessi risultati già ottenuti nelle prove eseguite utilizzando lo stesso rapporto percentuale di Fruttosio in acqua acidulata. 10 grams of Fructose were added to 100 milliliters of this cosmetic and, after having performed the same hair treatment operations already described in the previous pages, the same results were achieved already obtained in the tests performed using the same percentage ratio of Fructose in acidulated water.
Al termine del trattamento il capello si è presentato lucido, liscio, morbido al tatto, e con aspetto complessivo particolarmente gradevole. At the end of the treatment the hair was shiny, smooth, soft to the touch, and with a particularly pleasant overall appearance.
Analoghi risultati sono stati ottenuti effettuando quattro diverse prove con quattro miscele identiche a quelle degli esempi 1, 2, 3, e 4, utilizzando 100 millilitri di cosmetico al posto dei 100 millilitri di acqua acidulata. Similar results were obtained by carrying out four different tests with four mixtures identical to those of Examples 1, 2, 3, and 4, using 100 milliliters of cosmetic instead of 100 milliliters of acidulated water.
Il capello è risultato liscio, morbido al tatto e con particolare lucentezza se esposto ai raggi della luce solare od artificiale. The hair was smooth, soft to the touch and with a particular shine if exposed to the rays of sunlight or artificial light.
Ulteriori prove eseguite modificando la percentuale di Fruttosio aggiunta al cosmetico sopra indicato, ed altre prove miscelando il Fruttosio con le sostanze indicate nella tabella 2 nei rapporti ponderali dell’1%, 5 % , 15 %, 20 % , 30 %, 50 % ed 80 % hanno mostrato di poter fornire risultati simili a quelli ottenuti con le miscele di cosmetico contenente il 30 % in peso delle stesse miscele. Further tests carried out by modifying the percentage of fructose added to the cosmetic indicated above, and other tests by mixing the fructose with the substances indicated in table 2 in the weight ratios of 1%, 5%, 15%, 20%, 30%, 50% and 80% have been shown to be able to provide results similar to those obtained with cosmetic blends containing 30% by weight of the same blends.
Sperimentalmente si è infine appurato che il range ottimale d’uso è compreso entro il 5-25 % delle sostanze indicate nella tabella 2 in modo che la percentuale in peso di ciascuna di esse sia compresa nell’intervallo 5% - 25 %, con completamento a 100 costituito da sostanze inerti rispetto al fenomeno di lisciatura del capello riccio, crespo od ondulato . Experimentally it was finally ascertained that the optimal range of use is included within 5-25% of the substances indicated in table 2 so that the percentage by weight of each of them is included in the range 5% - 25%, with completion to 100 consisting of inert substances with respect to the phenomenon of straightening curly, frizzy or wavy hair.
