The range of dispersing agents (series OPARYL ® DT) is based on the chemistry of poly-naphthalene sulphonates (anionic surfactants). The series includes products with a low/medium/high molecular weight neutralised as sodium salts at various pH values.

The products also differentiate according to the various degree of sodium sulphate content. These products are used as high-efficiency dispersing agents for aqueous solutions or emulsions, as well as colloidal stabilizers. These properties enhance use of these products in the following fields of application:

  • formulation of pesticides
  • anti-caking agents for fertilizers
