Chemical background
The Hordaphos product group encompasses a wide range of different phosphoric acid esters. The Hordaphos grades are produced by the reaction of phosphorus pentoxide or polyphosphoric acid with an alcohol, whereby a mixture of mainly mono- and diesters and small amounts of triester and phosphoric acid is obtained.
Properties
A phosphoric acid ester is acidic as phosphoric acid and has similar phosphatizing properties. Due to the additional alcohol chain it is far less corrosive. The ionic phosphate functionality imparts antistatic properties to the molecule. Furthermore, when combined with a long chained alcohol the substance (e.g. Hordaphos 222) can be given strong dispersing properties. Thus, depending on the chain length and branching of the alcohol, the Hordaphos grade can be emulsifying, foam regulating, dispersing, wetting, dissolving, etc.
Application
As multifunctional additives they are used especially in household and professional cleaning products, but also in pigment pastes, paints, coatings, cosmetics, in formulations for metal working and metal cleaning, in textile production, crop protection, mining etc. Depending on the Hordaphos grades, the substance acts as a mild acid, corrosion inhibitor, brightener, antistatic agent, wetting agent, dispersing and/or emulsifying agent.
