Abstract
A novel class of compounds is described here. The disclosed novel compounds have one hydrophilic group and two identical hydrophilic ionic groups. The two hydrophilic groups of the disclosed compounds contain or end with a cationic or anionic charged group. The disclosed novel compounds herein can be used as surfactants in an article, product, or composition, or for some other purposes. A method to synthesize the disclosed novel compounds is also described.
