Phenol + 4EO Phosphate Ester - Potassium Salt
A very effective hydrotrope for low to medium alkaline formulations, and will help to solubilise conventional surfactants in these conditions. In high alkaline systems micelles are formed and surface activity becomes more enhanced.
Does not change the foaming, wetting of other surfactants in formulations
Hydrotrope to improve the solubility of nonionic and anionic surfactants
High Acid, Alkali and Electrolyte stability
Compatible with high levels of inorganic builders such as sodium potassium hydroxide, silicates, phosphates and polyphosphates
Becomes surface active in highly alkali formulations
Lanphos TEP4K isn't surface active at low alkaline levels as its unable to form micelles. This can be shown by the wetting profile below
Wetting draves 0.5g/l
However as you increase the pH then the product becomes more surface active and temperature increases can also enhance the surface activity.
