Abstract: Objective: The objective of this work was to evaluate the behavior of Acid Violet 43 pigment shampoos and conditioners formulations and when applied to hair through 10 formulations. Method: 10 formulations were developed, these being 5 shampoos and 5 conditioners. Among 5 shampoos, 4 were pigmented in different concentrations and 1 served as control. In the same way it was done for the conditioners, being 4 conditioners pigmented in different concentrations and 1 conditioner for control. The samples were subjected to organoleptic and physicochemical character-ization for 15 days, being evaluated appearance, color and odor, behavior after centrifugation, determination of pH, viscosity and foam content (for shampoo). Result: The samples showed satisfactory results in the tests, because their organoleptic and physicochemical characteristics remained stable throughout the analysis period. As for the behavior of the pigment on hair shaft, hair samples were bleached and washed with the formulations developed. Prewash and post wash solutions (wash water) were prepared at the same concentrations and were also read in a spectrophotometer at 570nm. For white, the depigmented products were used. It was observed that both the shampoos and the conditioners deposit pigment in the wires, however we verified by visual analysis that the conditioners are more effec-tive. Conclusion: The wicks were also subjected to moisture content tests to verify if pigment interfered with the deposition of water in hair.
