DESCRIZIONE DESCRIPTION
La presente invenzione concerne una composizione-filtro per la protezione della pelle contro i raggi violetti della banda C, denominati UVC. The present invention relates to a filter composition for the protection of the skin against the violet rays of the C band, called UVC.
L'energia del sole giunge sulla terra, dopo aver attraversato i vari strati dell'atmosfera, come radiazione solare che consiste in uno spettro continuo di diverse lunghezze d'onda che vanno dall'infrarosso e che, passando per la luce visibile, arrivano alla regione dell'ultravioletto. The energy of the sun reaches the earth, after passing through the various layers of the atmosphere, as solar radiation which consists of a continuous spectrum of different wavelengths ranging from infrared and which, passing through visible light, reach the ultraviolet region.
La radiazione infrarossa comprende lunghezze d'onda oltre i 770 nm.; la luce visibile ha lunghezze d'onda comprese tra i 400 e i 700 nm.; la radiazione ultravioletta comprende lunghezze d'onda tra i 290 nm. e i 400 nm. Infrared radiation includes wavelengths above 770 nm .; visible light has wavelengths between 400 and 700 nm .; ultraviolet radiation includes wavelengths between 290 nm. and the 400 nm.
La pelle risponde in maniera diversa a radiazioni di differenti lunghezze d'onda. La radiazione di ultravioletto della banda A, cosiddetta UVA, identificata anche come radiazione di ultravioletto ad onda lunga, ha lunghezze d'onda che vanno da 320 a 400 nm. con un picco massimo a 340 nm. The skin responds differently to radiation of different wavelengths. The ultraviolet radiation of the A band, so-called UVA, also identified as long wave ultraviolet radiation, has wavelengths ranging from 320 to 400 nm. with a maximum peak at 340 nm.
Questa banda è ritenuta responsabile dell'abbronzatura diretta della pelle, senza infiammazione o eritema preliminare, probabilmente dovuta alla fotoossidazione della melanina preformata negli strati superficiali della pelle. This band is believed to be responsible for the direct tan of the skin, without inflammation or preliminary erythema, probably due to the photooxidation of the melanin preformed in the superficial layers of the skin.
I raggi appartenenti a questa fascia di radiazione sono estremamente penetranti ed arrivano addirittura al derma dove provocano danni a collageno ed elastina con conseguente formazione di rughe precoci. The rays belonging to this radiation belt are extremely penetrating and even reach the dermis where they cause damage to collagen and elastin with consequent formation of early wrinkles.
La radiazione ultravioletta della banda B, cosiddetta UVB, ha lunghezze d'onda che vanno da 290 a 320 nm. Questa fascia di raggi ultravioletti è conosciuta anche come radiazione che provoca eritemi e scottature ed ha un picco massimo di efficacia attorno ai 297 nm. È la banda eritemogena della radiazione ultravioletta, responsabile della produzione di scottature e di reazioni irritative, ma in grado altresì di formare la melamina e di sviluppare la reale abbronzatura. The ultraviolet radiation of the B band, so-called UVB, has wavelengths ranging from 290 to 320 nm. This range of ultraviolet rays is also known as radiation which causes erythema and sunburn and has a maximum peak of efficiency around 297 nm. It is the erythemogenic band of ultraviolet radiation, responsible for the production of sunburn and irritative reactions, but also capable of forming melamine and developing a real tan.
Finora sono state proposte delle composizioni protettive contro le radiazioni solari che posseggono all'interno delle loro formulazioni due efficaci filtri per modulare o frenare l'attività dei raggi aventi le lunghezze d'onda delle bande B e A sopra citate. So far, protective compositions against solar radiation have been proposed which possess within their formulations two effective filters to modulate or curb the activity of the rays having the wavelengths of the bands B and A mentioned above.
In particolare il filtro per i raggi UVB è chimicamente il 2-etilesil-p-metossicinnamato che assorbe le radiazioni luminose con lunghezze d'onda da 290 a 320 nm. con un picco massimo attorno ai 300 nm. Le sue dosi di impiego vanno da un minimo di g. 0,60 ad un massimo di g. 9,95 per ogni 100 g. di prodotto. In particular, the filter for UVB rays is chemically 2-ethylhexyl-p-methoxycinnamate which absorbs light radiation with wavelengths from 290 to 320 nm. with a maximum peak around 300 nm. Its use doses range from a minimum of g. 0.60 to a maximum of g. 9.95 per 100 g. of product.
Il filtro per i raggi UVA è chimicamente il 4-ter-Bu-til-4-metossidibenzoilmetano, che assorbe le radiazioni luminose con lunghezze d'onda da 320 a 400 nm., con un picco massimo attorno ai 340 nm. Le sue dosi di impiego vanno da un minimo di g. 0,10 ad un massimo di g. 1,00 per ogni 100 g. di prodotto. The UVA filter is chemically 4-ter-Bu-til-4-methoxydibenzoylmethane, which absorbs light radiation with wavelengths from 320 to 400 nm., With a maximum peak around 340 nm. Its use doses range from a minimum of g. 0.10 to a maximum of g. 1.00 per 100 g. of product.
La radiazione ultravioletta ha però anche una banda C, conosciuta anche come radiazione germicida o radiazione corta, con lunghezze d'onda che vanno da 200 a 290 nm. Questa fascia di radiazioni, cosiddetta UVC, potrebbe essere estremamente dannosa per i tessuti cutanei, ma fortunatamente viene filtrata dall'ozono nell'atmosfera. Essa non stimola l'abbronzatura, ma può causare eritema per brevi esposizioni e addirittura cancro alla pelle per esposizioni più prolungate. L'arrivo dei raggi UVC sulla superficie terrestre è andato via via aumentando nel corso di questi ultimi anni a causa della progressiva riduzione della banda di ozono nella stratosfera terrestre, per cui è aumentato il pericolo di incorrere nei danni succitati. However, ultraviolet radiation also has a C band, also known as germicidal radiation or short radiation, with wavelengths ranging from 200 to 290 nm. This radiation belt, so-called UVC, could be extremely harmful to skin tissues, but fortunately it is filtered by ozone in the atmosphere. It does not stimulate tanning, but can cause erythema for short exposures and even skin cancer for more prolonged exposures. The arrival of UVC rays on the Earth's surface has gradually increased over the past few years due to the progressive reduction of the ozone band in the Earth's stratosphere, so the danger of incurring the aforementioned damage has increased.
Da più anni infatti gli scienziati si sono resi conto che alcune sostanze gassose, immesse nell'atmosfera a seguito di attività industriali, sono in grado di alterare l'equilibrio e la consistenza dello strato di ozono stratosferico. In fact, for many years scientists have realized that some gaseous substances, released into the atmosphere as a result of industrial activities, are able to alter the balance and consistency of the stratospheric ozone layer.
Grazie a studi approfonditi si è oggi in grado di dare, sul problema dell'impatto delle produzioni antropiche sull'ozono, un giudizio basato su solide acquisizioni scientifiche con margini di incertezza ormai ridotti. Thanks to in-depth studies it is now possible to give, on the problem of the impact of anthropic productions on ozone, a judgment based on solid scientific acquisitions with now reduced margins of uncertainty.
Sono state individuate almeno 40 specie chimiche diverse, coinvolte in più di 150 reazioni chimiche e fotochimiche che possono influenzare significativamente l'equilibrio dell'ozono nell'atmosfera e che hanno già resa drammatica la situazione in talune aree del globo terrestre. At least 40 different chemical species have been identified, involved in more than 150 chemical and photochemical reactions that can significantly influence the balance of ozone in the atmosphere and which have already made the situation dramatic in certain areas of the globe.
I danni sul DNA prodotti dalle radiazioni UVB e UVC assumono peraltro un grosso significato per ogni cellula vivente, coinvolgendo essi sia i microorganismi sia, ovviamente, i tessuti del corpo umano. The DNA damage produced by UVB and UVC radiation also takes on a big meaning for every living cell, involving both microorganisms and, obviously, the tissues of the human body.
Partendo da queste considerazioni è stato studiata e si propone ora una composizione-filtro per la protezione contro le radiazioni solari che ha una fascia di attività allargata fino a coprire le lunghezze d'onda più corte, ossia le radiazioni UVC finora mai prese in considerazione. Starting from these considerations, a composition-filter for the protection against solar radiation has been studied and is now proposed which has an extended activity band to cover the shorter wavelengths, that is the UVC radiation never considered before.
L'invenzione è pertanto diretta ad una composizione-filtro per la protezione della pelle contro i raggi ultravioletti della banda C, denominati UVC, secondo la rivendicazione 1. The invention is therefore directed to a filter composition for the protection of the skin against ultraviolet rays of the C band, called UVC, according to claim 1.
In conformità, la presente invenzione contempla una composizione-filtro sottoforma di emulsione, olio e/o gel contro la radiazione solare che incorpora, come sostanza attiva, il 2-idrossio-4-benzofenone che ha il potere di creare una barriera contro le radiazioni UVC, modulandone gli effetti. In accordance, the present invention contemplates a composition-filter in the form of emulsion, oil and / or gel against solar radiation which incorporates, as an active substance, 2-hydroxy-4-benzophenone which has the power to create a barrier against radiation UVC, modulating its effects.
Viene quindi proposta una composizione-filtro che, quando applicata, impedisce alle radiazioni UVC con lunghezze d'onda tra 250 e 290 nm., di penetrare nella pelle e provocare i ben noti danni da irritazioni, desquamazioni, alterazioni cellulari, fino a provocare il carcinoma cutaneo. A composition-filter is therefore proposed which, when applied, prevents UVC radiation with wavelengths between 250 and 290 nm., To penetrate the skin and cause the well-known damages from irritation, flaking, cellular alterations, up to causing the skin cancer.
In particolare poi, alla sostanza attiva destinata ad assorbire le radiazioni della banda degli UVC si possono addizionare altri composti per un'efficace protezione contro l'intera gamma delle lunghezze d'onda corrispondenti ai raggi ultravioletti. In particular, other compounds can be added to the active substance intended to absorb the radiation of the UVC band for effective protection against the entire range of wavelengths corresponding to ultraviolet rays.
L'invenzione è quindi diretta anche ad una miscela costituita dalla sostanza attiva che ricopre la lunghezza d'onda tra i 250 e i 290 nm. degli UVC addizionata con almeno una sostanza riflettente onde permettere di fornire una protezione per l'intero spettro delle radiazioni ultraviolette. The invention is therefore also directed to a mixture consisting of the active substance which covers the wavelength between 250 and 290 nm. of UVC added with at least one reflective substance to allow to provide protection for the entire spectrum of ultraviolet radiation.
Si crea così una valida barriera contro tutti i rischi di eritema e carcinogenesi, permettendo una regolare melanogenesi che sfocia com'è noto, in una piacevole abbronzatura. This creates a valid barrier against all the risks of erythema and carcinogenesis, allowing a regular melanogenesis that flows as is known, in a pleasant tan.
