In the original publication [1], there was a mistake in Table 4 as published; a technical error with table overlapping. The active compounds column was duplicated, and the pH value overlapped with the viscosity results from part B of Table 3. The correct Table 4 appears below. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
