PRODUTO DE PROTEÇÃO SOLAR E PROCESSO DE SOLAR PROTECTION PRODUCT AND
APLICAÇÃO DE PRODUTO DE PROTEÇÃO SOLAR À PELE APPLICATION OF SKIN SOLAR PROTECTION PRODUCT
A presente invenção refere-se na sua generalidade a produtos que propiciam proteção solar, adicionalmente contendo vitamina D3. The present invention relates generally to products providing sunscreen, additionally containing vitamin D3.
De forma particular, a presente invenção refere-se a formulações tópicas de qualquer natureza, particularmente cosméticas, dermatológicas ou dermocosméticas, que propiciam proteção solar e que adicionalmente contêm vitamina D3, particularmente sob forma de nanopartículas. In particular, the present invention relates to topical formulations of any nature, particularly cosmetic, dermatological or dermocosmetic, which provide sunscreen and additionally contain vitamin D3, particularly in the form of nanoparticles.
ANTECEDENTES DA TECNOLOGIA TECHNOLOGY BACKGROUND
A vitamina D é um hormônio esteroide lipossolúvel essencial para o corpo humano e sua ausência pode proporcionar uma série de complicações. Sabe-se que a vitamina D controla 270 genes, inclusive células do sistema cardiovascular. A principal fonte de produção da vitamina se dá por meio da exposição solar, pois os raios ultravioletas do tipo B (UVB) são capazes de ativar a síntese dessa substância. Alguns alimentos, especialmente peixes gordos, são fontes de vitamina D, mas é o sol o responsável por 80 a 90% da vitamina que o corpo recebe. Ela também pode ser produzida em laboratório e ser administrada na forma de suplemento, quando há a deficiência e para a prevenção e tratamento de uma série de doenças. Vitamin D is an essential fat soluble steroid hormone for the human body and its absence can provide a number of complications. Vitamin D is known to control 270 genes, including cells in the cardiovascular system. The main source of vitamin production is through sun exposure, because type B ultraviolet rays (UVB) are able to activate the synthesis of this substance. Some foods, especially fatty fish, are sources of vitamin D, but the sun is responsible for 80 to 90% of the vitamin the body receives. It can also be produced in the laboratory and given as a supplement when there is a deficiency and for the prevention and treatment of a variety of diseases.
A vitamina D é necessária para a manutenção do tecido ósseo, ela também influencia consideravelmente no sistema imunológico, sendo interessante para o tratamento de doenças autoimunes, como a artrite reumatóide e a esclerose múltipla, e no processo de diferenciação celular, a falta deste nutriente favorece 17 tipos de câncer. Vitamin D is necessary for the maintenance of bone tissue, it also influences considerably in the immune system, being interesting for the treatment of autoimmune diseases such as rheumatoid arthritis and multiple sclerosis, and in the process of cell differentiation, the lack of this nutrient favors 17 types of cancer.
Esta substância ainda age na secreção hormonal e em diversas doenças crónicas não transmissíveis, entre elas a síndrome metabólica que tem como um dos componentes o diabetes tipo 2. This substance also acts on hormone secretion and several chronic noncommunicable diseases, among them the metabolic syndrome that has type 2 diabetes as one of its components.
O consumo da vitamina é essencial para as gestantes, a falta dela pode levar a abortos no primeiro trimestre. Já no final da gravidez, a carência do nutriente favorece a pré-eclâmpsia e aumenta as chances da criança ser autista. Vitamin consumption is essential for pregnant women, lack of it can lead to miscarriages in the first trimester. At the end of pregnancy, nutrient deficiency favors preeclampsia and increases the chances of the child being autistic.
A vitamina D, além de ser obtida exogenamente, tem também síntese endógena. Necessita ser metabolizada até 1 ,25(OH)2D3, que é sua forma ativa e age similarmente aos hormônios esteroides. Origina-se de duas fontes: presente em fontes naturais na ingesta e a sintetizada na pele. A vitamina D da ingesta apresenta-se sob duas formas: D2 (calciferol), sintetizada em plantas a partir do precursor ergosterol e a D3 (colecalciferol), dos alimentos não vegetais. Ambas sofrem o mesmo processo de metabolização para se tornarem ativas. Vitamin D, besides being obtained exogenously, also has endogenous synthesis. It needs to be metabolized to 1,25 (OH) 2 D3, which is its active form and acts similar to steroid hormones. It comes from two sources: present in natural sources ingested and synthesized in the skin. Ingestion vitamin D comes in two forms: D2 (calciferol), synthesized in plants from the precursor ergosterol and D3 (cholecalciferol), from non-plant foods. Both undergo the same metabolization process to become active.
A vitamina D3 da pele é produzida a partir do 7-diidrocolesterol (pró-vitamina D3), precursor imediato do colesterol. Por ação da radiação solar (ultravioleta B), é transformada em pré-vitamina D3, que sofre uma isomerização induzida pelo calor, durante algumas horas, formando-se a vitamina D3. Skin vitamin D3 is produced from 7-dihydrocholesterol (pro-vitamin D3), the immediate precursor of cholesterol. By solar radiation (ultraviolet B), it is transformed into pre-vitamin D3, which undergoes heat-induced isomerization for a few hours, forming vitamin D3.
Entretanto, com a conscientização dos danos que a exposição constante aos raios solares proporciona é cada vez mais comum o uso de produtos que propiciam proteção solar, tanto aqueles especificamente para esse uso quanto produtos voltados a outras finalidades que contém, adicionalmente, filtros solares. Em consequência, vem se constatando um déficit de vitamina D na população devido à diminuição ou mesmo bloqueio completo da ativação da vitamina pelo sol devido ao uso produtos que propiciam proteção solar. However, with the awareness of the damage that constant exposure to sunlight provides, it is increasingly common to use products that provide sun protection, both specifically for this use and products intended for other purposes that additionally contains sunscreens. As a result, there has been a vitamin D deficit in the population due to the decrease or even complete blocking of vitamin activation by the sun due to the use of products that provide sun protection.
Dessa forma surgiu a necessidade de um protetor solar contemplando a nanotecnologia para liberação constante e controlada de vitamina D3, minimizando assim, o déficit proporcionado pelo bloqueio dos raios solares. Thus came the need for a sunscreen contemplating nanotechnology for constant and controlled release of vitamin D3, thus minimizing the deficit provided by blocking the sun's rays.
