The hair conditioners made of these gel networks were evaluated by a consumer panel for wet conditioning performance. The BTAMS gel network had a higher G', G'' and σ950 than the BTAC gel network. The rheology of the BTAMS gel network was more responsive to the concentration of the surfactant and fatty alcohols due to the bulk water phase outside the BTAMS lamellar gel phase. While the BTAC gel network swells accordingly depending on the concentration, nos sign of a bulk water phase was found. Despite the presence of a bulk water phase, the BTAMS lamellar gel was much stiffer than the BTAC lamellar gel, thus contributing to the higher G', G'' and sigma950, and making it difficult to break under conditions of stress (rinsing), which leads to a lower wet friction during rinsing that is noticeable to the consumer. The lower wet friction was not due to greater depostion of conditioning ingredients.
