I have formulated a foaming hand soap for my company. Our plant manager purchased a piston filler for this product and has complained that there is too much foam to fill the bottles at normal speed. I've been asked to dramatically reduce the amount of surfactant in my formula (yes, eliminating the foam from the foam soap.)
Is this necessary?
I've read about cross-hair nozzles and other fill methods for surfactant-containing products, but he insists it is a formulation issue.
The formula is about 18% active surfactant matter and I have been asked to reduce it to 5.4%. The new version obviously does not perform as well, but I seem to be the only one concerned.
