Resumo
A preocupação quanto ao aspecto sensorial faz com que vários formuladores opte pela utilização de diferentes tipos
de silicones em cosméticos, uma vez que, além de formarem uma película protetora no cabelo não oclusiva, melhoram o aspecto final do produto. Plantas como Matricaria chamomilla (camomila), Achyrocline satureoides
(macela) e Solidago microglossa (arnica de Brasil) são ricas em flavonóides e vêm sendo usadas em fórmulas
destinadas ao clareamento dos cabelos. Deste modo, este trabalho tem como objetivo verificar a efetividade dos
extractos dessas plantas, obtida por veículos extractores diferentes (hidroglicólico e hidrosilicônico), no
clareamento capilar. Os extractos, obtidos por percolação e por digestão seguida de maceração, foram aplicados em
mechas de cabelos castanhos claros, as quais posteriormente foram avaliadas por colorímetro de reflectância com o
objetivo de avaliar a qualidade da extração em termos de material extraído. Os resultados obtidos indicam que dentre
os diferentes veículos extractores, os melhores resultados foram obtidos com a mistura de água: DC 193 (PEG-12
dimeticone). Além disso, das três plantas pesquisadas, a camomila foi a que apresentou alterações estatisticamente
significativas de cor nas mechas de cabelos, evidenciando a ação clareadora deste extracto.
The concern how much to the sensorial aspect makes with that some formulators opt to the use of different types of silicons in cosmetics, a time that, beyond forming a protective film not occlusive in hair, improves the final aspect of the product. Plants as Matricaria chamomilla (camomila), Achyrocline satureoides (macela) and Solidago microglossa (Brazilian arnica) are rich in flavonoids and are being used in formulations destined to the clear hair. So, this work has as objective to verify the effectiveness of extracts of these plants, gotten for different extracting vehicles (hydroglycolic and hydrosiliconic), in the clear hair. The extracts, gotten for percolating and digestion followed of maceration, were applied in chestnut brown hair, which were evaluated by reflectance colorimeter with the objective of to evaluate the quality of the extraction in terms of extracted material. The results indicated that amongst the different extracting vehicles, the best results were obtained with the mixture of water: DC 193 (PEG-12 dimeticone). Moreover, of the three plants searched, camomila was that presented significant statistical alterations of hair color, evidencing the clear action of this extract.
