Abstract(s)
A indústria cosmética destaca-se atualmente pela crescente procura por produtos elaborados
com ingredientes naturais, em resposta aos efeitos adversos associados aos conservantes
e corantes artificiais. O presente estudo tem como foco o desenvolvimento de formulações de
batons de base natural, utilizando óleo essencial de eucalipto como conservante e as matrizes
Beta vulgaris L.. e Gomphrena globosa como fontes de corantes vermelho-rosa, ricos em
betalaínas. As matrizes foram extraídas utilizando protocolos padrão para obtenção de maiores
rendimentos em óleo essencial de eucalipto pela técnica de extração de Clevenger, e em
betalaínas pela técnica de maceração. Os extratos obtidos foram avaliados quanto às suas atividades
antioxidante e antimicrobiana e foram posteriormente incorporados em dois produtos
finais diferentes (duas formulações de batom e duas formulações de lip tint). Essas formulações
foram avaliadas ao longo de 15 dias, incluindo análises físico-químicas (espectro de cores e pH)
e bioatividade. Os resultados indicaram um decréscimo das propriedades antimicrobianas do
agente conservante nas amostras testadas, Os batons apresentaram maior atividade antioxidante
quando formulados com o corante obtido da G. globosa. Ambos os corantes sofreram alterações
pouco significativas de cor ao longo do tempo. Conclui-se que o corante da G. globosa obteve o
melhor resultado na análise antioxidante, na análise sensorial, apresentou amostras mais homogéneas
e pouca mudança de coloração, evidenciando sua viabilidade em formulações naturais
na indústria cosmética.
The cosmetics industry is currently distinguished by the increasing demand for products made with natural ingredients, in response to the adverse effects associated with artificial preservatives and dyes. This study focuses on the development of natural-based lipstick formulations, using eucalyptus essential oil as a preservative and the matrices B. Vulgaris and G. Globosa as sources of red-pink dyes, rich in betalains. The matrices were extracted using standard protocols to obtain higher yields in eucalyptus essential oil by the Clevenger extraction technique, and in betalains by the maceration technique. The obtained extracts were evaluated for their antioxidant and antimicrobial activities and were subsequently incorporated into two different final products (two lipstick formulations and two lip tint formulations). These formulations were evaluated over 15 days, including physicochemical analyses (color spectrum and pH) and bioactivity. The results indicated a decrease in the antimicrobial properties of the preservative agent in the tested samples. The lipsticks showed higher antioxidant activity when formulated with the dye obtained from G. Globosa. Both dyes underwent insignificant color changes over time. It is concluded that the dye from G. Globosa obtained the best result in the antioxidant analysis, while the sensory analysis, presented more homogeneous samples and little color change, evidencing its viability in natural formulations in the cosmetics industry.
