Desenvolvimento de cosmético contendo ácido Alfa-Lipóico para prevenção de alterações da pele e do envelhecimento cutâneo

Abstract

Diversos antioxidantes demonstram considerável efeito na prevenção do câncer por reduzir o estresse oxidativo causado por uma ampla variedade de ataques: biológicos, químicos e físicos, dentre os quais a radiação solar ultravioleta (UV) é o estresse físico ambiental descrito entre os mais freqüentes ataques que ocorrem sobre a pele, o qual está associado no desenvolvimento na maioria das doenças, incluindo o câncer. Vários componentes da dieta podem ser utilizados sozinhos ou em combinação com fármacos convencionais para prevenir doenças. Ainda, a busca por metodologias alternativas à experimentação com animais para o teste de eficácia de formas cosméticas de uso tópico é devido à pressão pública existente neste sentido, introduzida principalmente pela Comunidade Européia (93/95/EC). O presente estudo teve por objetivo avaliar a atividade do ácido alfa– lipóico em cultura de células, além do estudo de estabilidade de emulsões O/A e seu comportamento reológico. Para isto, foram utilizadas culturas de células como modelo experimental, na tentativa de desenvolver um método alternativo à experimentação com animais que poderá ser utilizado pela indústria cosmética. Foram utilizadas culturas de células HepG2 (metabolizadoras de xenobióticos) e cultura de células HaCaT (queratinócitos)

Several antioxidants show significant effect in preventing cancer by reducing oxidative stress caused by a wide variety of attacks: biological, chemical and physical agents, amongst which the sun's ultraviolet (UV) is the most physical stress environment described among the most frequent attacks that occur on the skin, which is associated with development in most diseases, including cancer. Several dietary components can be used alone or in combination with conventional drugs to prevent disease. Still, the search for alternative methods to animal testing to test the efficacy of topical cosmetic forms is due to public pressure that exists in this sense, introduced mainly by the European Union (93/95/EC). This study aims to assess the activity of alpha-lipoic acid in cultured cells, in addition to studying the stability of O / W emulsions and their rheological behavior. For this, cell cultures are used as experimental models in an attempt to develop an alternative method to animal testing that may be used by the cosmetics industry. Will be used HepG2 cell cultures (xenobiotic metabolizing) and cell culture of HaCaT (keratinocytes)
