QCM-D data showing the shift of Δf5 values for 1–20 ppm HOCl stabilized with A 0.14% or B 2% HAc as a function of exposure time. The final concentration of HOCl is indicated inside each grey bar zone. Grey and white zones indicate contact between the HA surface and test solutions or rinsing with Milli Q water respectively
