The quantity of the DDA-based formulation (ContraZeck®) applied per test was about 1 mg/cm2, corresponding to approximately 0.1 mg DDA/cm2. # The reference product Zanzarin® (Bio-Hautschutz Lotion) was applied per test in a concentration of 1.05 mg/cm2. Significance: *in relation to blank test, **in relation to Zanzarin®. Differences in repellency between both products are significant only 4 hours after application. | ||||||||
