If rate of micelle growth and resultant aggregation properties are used as a proxy for viscosity, on the assumption that large WLMs which lead to high viscosity will have a high (or larger) aggregate size, then the simulated results correlate well with the experimental data. Systems that have faster growth and larger resultant aggregates are in broad agreement with regions of high experimental viscosity. The exception to this agreement is for the low pH systems that were turbid (or unstable) in the laboratory.
