Dyes are extracted from seeds of annatto (Bixa orellana L.) is studied and its stability as a powder applied to a base cosmetics. We use an experimental design, employing the extraction temperature and the relation between load and solvent as input variables, and the yield on total coloring and bixin content in the final product, as responses. It appears that the income in total coloring can be estimated by a first order polynomial model and the field experimental conditions; the content of bixin is not statistically affected. A change of color is evidenced by tristimulus colorimeter system,xCIE L*a*b*.
