- Background on Phosphate Esters
- Phosphate Esters are anionic surface active agents produced by reacting polyphosphoric acid or phosphorous pentoxide with molecules containing hydroxyl groups - commonly ethoxylated moieties or alcohols. Reactions using phosphorous pentoxide result in a mix of mono and di-esters, while products made with polyphosphoric acid are high in mono-ester yield.
- Which type to use depends upon the properties needed in formulation. Mixed esters products are generally better for emulsification; whereas, mono- ester rich exhibit better hydrotroping properties.
