Adding 2%sunflower oil to foam bath with SLES and Cocamide DEA made the foam bath thicken. Why?
2% oil was added to 100ml foam bath containing sles and cocamide dea. It thickened the foam bath. To the next experiment we added 5% dishwashing liquid emulsified with 1ml sunflower oil to 100ml foam bath and it also thickens. Why? I have assumed we are dealing with a macro emulsion in the first case and a mixed micelle emulsion secondly. Can u help?
