The age of micellar solution influences substantially effectiveness of drag reduction in a turbulent flow in tubes. In this contribution are shown effects of both surfactant concentration and the ratio of the surfactant to the compound containing counter ion, and their role in degradation rate at aging. Experiments were made with different concentrations of cationic surfactant CTAB (Hexadecyltrimethyl ammonium bromide) in mixture with NaSal (Sodium salycilate).
