In short: Load the technical or its solution onto the carrier under the same conditions the plant uses, then run the standard formulation checks — wet sieve, suspensibility, wettability and, for WG, disintegration and attrition — against the incumbent carrier. Sensilchem supplies inert carriers only and takes no position on active ingredients; CENSIL 260P is the starting point, with 265P and 280P for higher liquid loads.
Every step here concerns the carrier. Handling, exposure limits and disposal for the active ingredient are set by its own SDS and by your site rules, and nothing in this guide changes them.
Blend the active onto the moving carrier at plant-like shear and stop at the same load the production formulation uses. For a liquid technical, add it in stages and watch for balling as you would in a premix.
A carrier behaves differently after milling. If the production route mills the blend, mill the trial blend on the same type of mill before running any formulation test.
Wet sieve residue, suspensibility and wettability on the treated blend against the incumbent, using the methods your registration file already cites. A carrier change is a formulation change and is judged by the same tests.
Granulate the blend on the plant route, then run disintegration, attrition and dust tests. A carrier that makes a good WP can make a granule that is either too hard to disperse or too soft to ship.
Hold the formulation warm for the period your stability protocol requires and repeat the tests. Carrier interaction with an active generally shows up as a change in suspensibility over time, not on day one.
No. We supply the inert carrier, provide its documentation and describe how to run the carrier trial. Compatibility with a specific active is the formulator's determination.
Start on CENSIL 260P; if the target load is held but the blend stops flowing, move to 265P, and use 280P when the liquid load itself is the constraint.
The material you use now, the formulation or resin, the equipment and the target you need to hit. That is enough for us to say whether we have something worth testing.
