Abstract
This study aims to identify and analyze the tannins from walnut extract obtained by discontinuous methods (infusion and maceration) and continuous methods (Soxhlet extraction). Experimental data show that walnut extracts obtained by discontinuous processes have a higher yield and a much higher content of tannins than those obtained by continuous processes. The walnut samples were used in cosmetic formulation of a shampoo.
