An insight into our innovative portfolio

PTSA as an aid to leak detection in water-bearing systems

The product known as PTSA (1,3,6,8-pyrenetetrasulfonic acid tetrasodium salt, CAS: 59572-10-0) is a water-soluble, anionic fluorescent dye that, when combined with appropriate instrumentation, can be used to easily reveal leaks in water-bearing systems. Using PTSA can also help you to monitor the composition of the water in your system in real time and thus to prevent deposits. PTSA lends itself well to these applications because it is highly water-soluble, detectable as low as ppb, chemically stable, and gives off clear spectra when applied.

We offer the product in powder form so that it can be used easily in your system in specific doses.


Expansion of our portfolio of complexing agents

Alongside products based on phosphonate, our TERquest portfolio also features the complexing agents TERquest GLDA (tetrasodium N,N-bis(carboxylatomethyl)-L-glutamate) and TERquest MGDA 40% (methylglycine diacetic acid trisodium salt).

These are also antiscalant products. The products are able to complex metal ions and keep them in solution to prevent deposits on things like water-bearing elements. Areas of application are therefore water treatment plants, cooling circuits, boiler water treatment, etc. The liquid dosage form of the products allows easy and accurate dosing in your process and saves you having to dissolve the products.

We offer TERquest GLDA in two concentration levels, with active content of 38 % and 47 %.

In your process, use of the products TERquest GLDA and TERquest MGDA 40 % offers you the following advantages:

  • Produced from bio-based materials
  • Good biodegradability

These properties can also lead to a lower carbon footprint and a better categorization of your product.


Tonsil Optimum 218 FF – bleaching earth for bio-oils

We've recently expanded our product portfolio to include Tonsil Optimum 218 FF in addition to the acid-activated bleaching earths from Clariant's Tonsil range. Tonsil Optimum 218 FF stands out due to its exceptional ion exchange capacity, making it a versatile choice for refining a wide variety of oils. This product is an activated bleaching earth primarily derived from calcium bentonite.

What sets this particular grade apart is its unique activation process, which doesn't involve the use of acids or other chemicals. This characteristic makes Tonsil Optimum 218 FF suitable for the purification of not only conventional oils but also bio-oils and RBD oils. When incorporated into oils, Tonsil plays a pivotal role in eliminating undesirable odors, flavors, and other impurities from the medium.

Furthermore, our comprehensive range of Tonsil products includes various other grades, ensuring a diverse selection to meet your specific needs.
