The effect of carbon chain length and high vs. low 2-phenyl isomer distribution on viscosity and solubility (cloud/clear point) of a liquid hand dishwashing formulation is shown in Table 5. Two sets of pure LAS homolog samples ranging from Cl0 to Cl3 were prepared. All samples were prepared with pure olefins, but one set was produced with an HF alkylation catalyst (low 2-phenyl) and the other set was alkylated with A1C13 (high 2-phenyl). Each LAB... 

An early hand dishwashing detergent is compared to a more recent formulation in Table 3.3. From this comparison one can see that the basic components have not changed much over the years. It is clear that surfactants have been and continue to be the most important ingredients, responsible for cleaning and foaming. 

Imagine five people working together to wash a stack of very greasy dishes. The first two clear the table and hand the dishes to the third person who washes them and hands them on. The last two persons dry and stack them. Which step is likely to be the rate determining step In the light of your answer, discuss how the rate of the overall process would be affected if a sixth person joined the group (a) as a table clearer (b) as a second dishwasher (c) as a dish dryer.
