Hydrotroping
The following hydrotrope efficiency was determined by titrating the hydrotrope into a solution containing 8% builder (composed of 30% sodium metasilicate, 30% sodium tripolyphosphate and 40% sodium carbonate) and 2% SYNPERONIC™ 91/6. MULTITROPE 1214 was compared to Sodium xylene sulfonate (SXS) and performed better than this benchmark. MULTITROPE 1214 must be neutralized prior to bleach addition to avoid the generation of chlorine gas.
Figure 1: MULTITROPE 1214 hydrotrope efficiency
The following table (Table 1) shows the effectiveness of MULTITROPE 1214 as a hydrotrope compared to competitive products.

MULTITROPE 1214 contributes excellent hard surface wetting to the following formulation (Test Formulation 1), as the following graph clearly illustrates:
Figure 2: Improved wetting of sanitizers
In a comparative use test on bathroom tiles using the above formulation, the solution containing MULTITROPE 1214 removed mildew faster than the control or the solution containing sodium hypochlorite and sodium dodecyldiphenyloxide disulfonate. In addition, MULTITROPE 1214 dramatically improves the wetting properties and surface tension reduction of the hypochlorite sanitizer/cleaner, as illustrated below:

Most surfactants degrade in the presence of sodium hypochlorite and reduce the available chlorine in the hypochlorite solution. MULTITROPE 1214 will not degrade in the presence of sodium hypochlorite. MULTITROPE 1214 when compared to a commonly used ‘hypochlorite stable’ surfactant, at equal activity, shows greater available chlorine after 6 months at 25ºC. (Sodium dodecyl diphenyloxide disulfonate)
