Resumo
Na medicina tradicional chinesa, acredita-se que o extracto de pérola pode nutrir a pele e prevenir o processo de envelhecimento. Assim, o objectivo deste estudo foi avaliar as características reológicas, os efeitos imediatos sobre a pele e as propriedades sensoriais de uma formulação cosmética à base de silicone contendo extracto de pérola. As formulações contendo extrato de pérola ou não foram foram submetidas a ensaios de estabilidade física por determinação do comportamento reológico durante 28 dias de armazenamento. Uma vez que as formulações se mostraram estáveis, elas foram aplicadas na região interna do antebraço de 15 indivíduos saudáveis do sexo feminino para avaliar as condições da pele usando técnicas não-invasivas. Após uma única aplicação, as formulações aumentaram o conteúdo de água do estrato córneo. Quando as formulações foram aplicadas no antebraço para a análise sensorial, a maioria dos voluntários notaram que ambas as formulações melhoraram todos os atributos sensoriais da pele, mas que apenas a formulação com extrato de pérola mostrou as maiores notas para todos eles. Os resultados sugerem que a formulação à base de silicone adicionada de extracto de pérolas pode combinar propriedades sensoriais únicas e eficácia para melhor atender a demanda dos consumidores.
In traditional Chinese medicine, pearl extract is believed to nourish skin and prevent the aging process. Thus, the aim of this study was to evaluate rheological characteristics, immediate effects on skin, and sensory properties of a silicone-based cosmetic formulation containing pearl extract. Formulations containing pearl extract or not were submitted to physical stability assays by determinations of its rheological behavior during 28 days storage. Once confirmed the formulation’s stability, they were applied on the volar forearm of 15 healthy female to evaluate skin properties by non-invasive techniques. After a single application, formulations increased the stratum corneum water content. Once applied on the volar forearm for sensory analysis, the volunteer’s majority noted that both formulations improved all the sensory skin attributes, but only the pearl extract formulation has shown the higher scores for all attributes. Results suggested that the silicone-based formulation supplemented with the pearl extract could combine unique sensory properties and effectiveness to better meet consumer’s demand.
