Returning to the region identified as turbid by the laboratory measurements, herein lies the main source of discrepancy between simulation and experiment. At low pH and CAPB / SLSar values, the turbid laboratory samples initially had a very high viscosity, which reduced to low viscosity after a few hours. This is in agreement with results observed by Vu et al. . Note that we observe a pH threshold for turbid mixtures that varies with the mole ratio of CAPB to SLSar (Table ) which further supports the idea that the micellar environment affects pK a discussed in previous sections. In the regions defined as turbid by laboratory testing, our simulations report multiple different behaviors. At the lowest pH sampled by simulation (i. e. pH 3.9) for the CAPB / SLSar mole ratios of 0.0, 0.25 and 0.67 we observe large aggregates, displaying a relatively large degree of branching, with a dominant cubic power law defined micelle growth region towards the final configuration.
