Crystal growth inhibition strategies in suspension concentrate formulations with case studies
INGEVITY IN THE NEWS
Crystal growth is one of the largest challenges in agrochemical suspension concentrate (SC) formulations. In a recently published article in the May 2022 AgroPage issue, Ingevity discussed mechanisms and tools formulators can use to control crystal growth. The most important component is choosing a high-performing dispersant that can provide strong coverage of active ingredient particle surface. Secondly, adding a crystal growth inhibitor to lower active ingredient solubility, or introducing competing “impurity” to slow down active ingredient molecule re-adsorption process can dramatically reduce crystal growth. Lastly, using combination of non-ionic and anionic surfactant blend and appropriate amount of thickener can also help stabilize the system. This article highlights several case studies utilizing these strategies to successfully control crystal growth in these challenging SC formulations. Read more…
