Our products are used in a wide range of applications.


Agricultural chemistry

Aromatic solvents are used as inert solvents in formulations to keep active ingredients (AIs) stable in formulations over a variety of storage and transport conditions. 


Fuel additives

Aromatic solvents act as carrier fluids for individual additive formulations. They are suitable for critical ingredients such as defoamers, demulsifiers and corrosion and fouling inhibitors, octane and cetane improvers, extreme pressure and cold flow additives. 


Oilfield chemistry

Production chemicals are a key player in oil field applications and our Caromax grades provide the ideal solvency matrix for this. Haltermann Carless supplies to proprietary oilfield chemical formulators of corrosion inhibitors, detergent packages and flow improvers for protecting oil field assets. 



Aromatics are universal solvents for components of a paint or coating. Therefore, they are ideally suited for bringing together resin, additives, pigments and colorants in one formulation. The application of these paints mostly extends to the professional, industrial sector.
