Pesticide rheology modifier  Organoclay

Organobentonite pesticide rheology modifier for oil-based, water-based, and universal liquid pesticide formulations. Improve suspension stability and reduce settling.

Our oil-compatible organobentonite grade — an organophilic clay modified for non-aqueous systems — is designed for oil-based and solvent-based agrochemical formulations.

**Typical applications include:**

– Oil dispersion formulations (OD)
– Oil-based suspension concentrates
– Herbicide formulations
– Fungicide formulations
– Insecticide formulations
– Botanical pesticide formulations
– Other liquid pesticide systems based on carrier oils or organic solvents

This organoclay helps build a thixotropic structure in the oil phase, supporting the suspension of insoluble active ingredients and reducing sedimentation during storage.

2. Organoclay for Water-Based Pesticide Formulations

Our water-compatible organobentonite grade is designed for aqueous pesticide systems where suspension stability and controlled rheology are required.

**Typical applications may include:**

– Aqueous suspension concentrates (SC)
– Water-based insecticides
– Water-based fungicides
– Water-based herbicides
– Suspo-emulsion systems (SE)
– Other water-based agrochemical formulations

This grade helps improve the structure of the water-based system, supporting the uniform dispersion of solid active ingredients and reducing settling during storage.

**Key functions:**

– Suspension stabilization
– Sedimentation control
– Rheology modification
– Viscosity adjustment
– Improved storage stability
– Redispersion support

Frequently Asked Questions

**What is a pesticide rheology modifier?**
A pesticide rheology modifier is an additive used to control viscosity, yield value, suspension stability, sedimentation, flow behavior, and redispersibility in liquid agrochemical formulations. Organobentonite and organoclay are common types of rheology modifiers used in this field.

**What is organobentonite used for in pesticide formulations?**
Organobentonite — also referred to as organoclay or organophilic clay — is used as a suspension aid, anti-settling additive, and rheology modifier. It helps maintain the dispersion of solid active ingredients and supports physical stability during storage.

**What is the difference between organobentonite and organoclay?**
Organobentonite is a specific type of organoclay produced by modifying bentonite clay with organic quaternary ammonium compounds. The terms are often used interchangeably in the coatings, greases, and agrochemical industries. Both refer to organophilic clay materials that provide rheological control in non-aqueous or selected aqueous systems.

**Which organoclay is suitable for oil-based pesticides?**
The oil-based grade is designed for oil dispersion formulations and other non-aqueous pesticide systems. It should be evaluated with the selected carrier oil, solvent, active ingredient, and dispersant system.

**Which organoclay is suitable for water-based pesticides?**
The water-based grade is designed for aqueous pesticide formulations where suspension stability and rheology control are required.

**What is the universal organoclay grade?**
The universal grade is designed for flexible formulation development and can be evaluated in both oil-based and water-based pesticide systems.

**Can organoclay prevent pesticide sedimentation?**
Organoclay can help reduce sedimentation by creating a controlled rheological structure in a compatible formulation. Actual performance depends on the formulation chemistry, particle size, dosage, and processing conditions.

**How much organobentonite should be added?**
There is no universal dosage. The optimum level should be determined through laboratory testing based on the active ingredient, formulation type, target viscosity, and required storage stability.
