Surfactants phosphonates are derived from phosphonic acid n-alkane, which are diprotic. This allows a variety of properties derived from the degree of neutralization, which allow both use in practical applications such as in basic studies of physicochemical properties of amphiphilic derived from the burden of its polar group, which can be varied from zero (acting as surfactants nonionic quasi) to 2.

This has given them a number of features that is useful to know if a study on their applications is undertaken. Phosphonic acids and their salts have a lot of technological applications such as flotation processes minerals, ion extraction, as ligands, in the manufacture of polymers, as additives in the paper industry, as corrosion inhibitors, and as detergent additives, among other uses. The number and variety of applications phosphonates do not cease to grow. However, a family of phosphonates, surfactants, despite their current and potential applications, has been little studied.
