Safety Data Sheet
Technical Data Sheet

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.

Key Properties

​

  • 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: See Blog

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

However as you increase the pH then the product becomes more surface active and temperature increases can also enhance the surface activity.
