Table 1.

Compilation of possible modifications of xanthan gum, resulting properties and their relevance for agricultural applications (own data).

Property Description Modifications Relevance for application
Reduced pseudoplasticity
  • Lower viscosity at low shear

Fermentation conditions
  • Smooth flow, better pourability of agrochemical formulations

  • Better sprayability at low pressure

  • Easier soil infiltration

Salt tolerance
  • Extra high viscosity in the low shear range also in presence of salts

  • Fast hydration also in presence of salts

Fermentation conditions
  • Formulation of fertilizers

  • Agrochemical formulations

Acid stable
  • Maintenance of viscosity in low pH solutions

Fermentation conditions
  • High stability of low pH disinfectants

Dust free
  • Absence of fine dusts

Oil coating
  • Better handling in manufacturing process

Clear solution
  • Transparent appearance of xanthan gum solution

Additional clarification
  • Formulation aesthetics

Easily dispersible
  • Easy dispersion and reduction of lumping also under slow agitation

Agglomeration
  • Lump‐free hydration, e.g. when adding as dry product in the spray tank
