  3. Oil Dispersion (OD)

Oil Dispersion (OD)


An oil dispersion (OD) formulation is a solid active ingredient dispersed in oil. The oil can vary from paraffinic to aromatic solvent types and vegetable oil or methylated seed oils. Ideally the active ingredient is uniformly suspended in the oil phase.

ODs are an excellent delivery system for water sensitive active ingredients such as sulfonylureas. However, ODs have extended to other active ingredients due to their better spray retention, spreading and foliar uptake as the carrier oil often acts as an adjuvant.

Benefits

  • Especially suited to hydrolytically unstable actives allowing them to be formulated as liquid formulations
  • The oil continuous phase acts as a built-in adjuvant
  • The oil adjuvant can provide both penetration enhancement and spray retention enhancement
  • Does not need preserving (water free)

  • Emulsifier
  • Non-aqueous Dispersant
  • Oil
  • Rheology Modifier

Aqueous Dispersant

Aqueous dispersants are used in some cases in order to improve stability in the spray tank after dilution in water. If the active ingredient is insoluble in water and needs to be suspended for a length of time, the aqueous dispersant will prevent flocculation of these solid particles and improve overall stability.

Emulsifier

Emulsifiers are necessary in order to emulsify the continuous oil phase into water when the OD formulation is diluted prior to being sprayed. Emulsifiers are selected based upon their ability to spontaneously form this emulsion. Their performance is primarily dictated by the nature of the surfactant and their collective effect on how they arrange themselves at the oil/water interface.

Non-aqueous Dispersant

Non-aqueous dispersants are used to disperse the active ingredient in the oil continuous phase and provide long term stability. In an OD solid particles are susceptible to flocculation leading to an increase in particle size and formulation instability. To prevent this, the use of a polymeric dispersant is highly recommended.

Oil

Oil composition and quality may impact formulation performance either upon production or upon extended storage. Variations from oil to oil can commonly occur depending on the source so strict specifications should be applied to the chosen oil and stuck to throughout the lifetime of that material. Croda’s range of Seatons Refined Oils are 100% natural and renewable. They are also impurity free and have a good compatibility with many active ingredients which make them a great choice for use in crop care formulations.

Rheology Modifier

Rheology modifiers are an essential part of an OD formulation. If the formulation is not stabilised effectively the solid active ingredient(s) will sediment forming a hard pack layer preventing re-dispersion. A common way to reduce this sedimentation is to increase the viscosity of the continuous phase using a rheology modifier.
