Triisopropanolamine, a surfactant, possesses the remarkable capability to lower the surface tension of water, resulting in the formation of micelles. These micelles, small spherical structures, consist of molecules exhibiting mutual attraction. Through this formation, micelles readily engage with proteins and other molecules, enabling their dispersion within a solution. Moreover, Triisopropanolamine can establish hydrogen bonds with proteins, influencing their structure and function in a significant manner.
