The aim of this study was to evaluate different manufacturing processes of compact powders and establish consumer preferences through sensory analysis. Four compact powders were formulated with the following treatments: micronization, hammer mill, addition of raw materials that modify the sensory, and simple mixture. The powders were compressed, passing the tests for glazing, detachment of color and drop test, and later forwarded to sensory evaluation by 45 volunteers. In the compression tests, drop test, glazing and detachment of color, the micronized sample obtained the best results showing the reduction of particle size influences the packaging of powders and improves the compression of the product, but in the sensory analysis the sample obtained by simple mixture was the preference of most of the volunteers. It was felt that, despite the best compaction results are obtained for samples micronized, the preference of the volunteers is still linked to older manufacturing processes where the resulting powder shows more coarse and form a thicker layer on the skin.
