Griton TEP4K

Background

Griton TEP4K is a phosphate ester manufactured using polyphosphoric acid resulting in a product that is predominantly mono-ester. The main advantage of a phosphate ester over a conventional anionic is it’s excellent stability in high concentration of acid, alkali and electrolyte.

Griton TEP4K is supplied in neutral form as a potassium salt and behaves as a hydrotrope for the solubilisation of both anionic and nonionic surfactants into high concentration of electrolyte.

Typical application areas are:
Industrial and Institutional cleaning - superior hydrotropic performance compared to sodium xylene sulphonate. Griton TEP4K is especially recommended as a hydrotrope for the solubilisation of low foam surfactants into highly built liquids for applications such as bottle washing, low foam alkaline cleaning and liquid machine dishwashing.
