We find the best way to utilize MACAT AEC in hypochlorite cleaners is to follow this order
of addition:
- Charge water to the vessel
- Add MACAT AEC and other surfactants/ingredients
- Add NaOH (if even to neutralize the MACAT AEC)
- Finally, add hypochlorite solution
When we try to troubleshoot for a customer, we typically like to know
- The concentration of the hypochlorite
- Quality of the hypochlorite used
- Concentration and ratios of MACAT AEC used in the formulation
As most formulators have learned, when formulating with hypochlorite, the greater the initial hypochlorite concentration the greater its fall. We characterize the quality of the hypochlorite in the market as relating to the NaCl and NaOCl content. An acceptable standard quality of approx. 130 - 150 g/L NaOCl with approx. 13 - 15% of NaCl is recommended. Generally, the higher the content of NaCl in the hypochlorite solution the lower the phase stability of the resultant formulation. We have found that some formulations, and in particular the solubilizing of some fragrances, benefit from a blend of MACAT AEC surfactants.
