Tonnegel™
Tonnegel™ is an attapulgite-based rheology modifier that prevents settling and phase separation in agricultural liquid formulations and seed treatment systems.
Its unique thixotropic properties allow formulations to flow easily during application while maintaining structure at rest, ensuring uniform dispersion of nutrients and active ingredients even in complex systems.
By forming a stable colloidal network, Tonnegel™ enhances formulation stability, improves handling and processing, and delivers consistent performance across a wide range of agricultural applications.
Sourced from Clariant’s own mineral reserves in Florida and Georgia, Tonnegel™ offers reliable quality, supply security, and consistent performance.

Tonnegel é usado nas seguintes aplicações:
• Ração líquida para animais
• Fertilizantes em suspensão
O Tonnegel é comumente usado como espessante e agente de suspensão em ração líquidas para animais e fertilizantes em suspensão. Ele efetivamente mantém minerais, nutrientes e ingredientes ativos uniformemente dispersos, evitando a ocorrência de sedimentação e sinérese.
The Tonnegel™ portfolio includes different grades tailored to formulation needs:
- Tonnegel™ 350 – High-performance gel grade for demanding suspension systems
- Tonnegel™ 40 / 50 – Fine particle grades for improved dispersion and stability
- Tonnegel™ 30 – Versatile option for general applications
Grade selection should be based on formulation requirements, desired viscosity profile, processing conditions, and compatibility with other active ingredients. Contact Clariant’s technical team for formulation guidance.
Q: What does ‘thixotropic’ mean and why does it matter for agricultural formulations?
A: Thixotropic means a material becomes less viscous when subjected to shear stress (such as stirring, pumping, or spraying) and recovers its viscosity when at rest. In agricultural formulations, this is highly desirable: it allows the product to flow easily through pumps and nozzles during application, while maintaining suspension stability and preventing settling when stored in tanks or containers.
Q: Can Tonnegel™ replace xanthan gum or other biopolymer suspension agents?
A: Yes. Tonnegel™ is specifically designed as a full or partial replacement for conventional suspension agents including xanthan gum, guar gum, and sepiolite-based systems. Its mineral origin makes it less susceptible to microbial degradation and provides more consistent rheological performance across temperature ranges — common limitations of biopolymer-based systems.
Q: Is Tonnegel™ compatible with biological seed treatments?
A: Tonnegel™ has broad compatibility with multi-component seed treatment systems, including those containing biological inoculants. However, compatibility should always be validated through formulation testing, particularly for sensitive microbial strains or high-concentration biological products.
Q: Where is the attapulgite for Tonnegel™ sourced?
A: Tonnegel™ is produced from attapulgite (palygorskite) clay minerals sourced exclusively from Clariant’s own mining operations in Florida and Georgia, USA. This vertical integration ensures consistent raw material quality, supply reliability, and traceability.
