Table 5.

Rank order of different formulations presented in Test 2 with varying carrageenan and carbopol concentrations, in order of preference from most preferred (1) to least preferred (3) along with calculated Rank Sum. Upper case letters denote statistically significant differences between the rank sum for the different formulations. Lower number indicates greater preference.
