Thermoresponsive foams that refer to foams for which the stability can be switched between the stable and unstable state have recently attracted growing interest due to their possible industrial applications. Our approach to design such foams is based on the use of fatty acids, with various counterions and molar ratios. It is the first example of foams with a temperature threshold of destabilization which can be continuously set between 20 °C and 75 °C.
