Abstract: Crystal growth inhibitor compositions useful for agricultural formulations are disclosed. The compositions comprise a comb copolymer dispersant and an alkyl-capped polyalkoxylate. The dispersants comprise recurring units of styrene, methacrylic acid, and a methacrylate ester of an alkyl-capped polyalkoxylate having a number average molecular weight within the range of 300 to 3,000 Da. The inhibitor compositions are effective for agricultural actives that tend to crystallize or form large aggregates upon storage for even a short time, including pesticides from the acylalanine, oxyacetamide, triazinone, sulfonylurea, strobilurin, halogenated pyrrole, neonicotinoid, triazole, and pyridine carboxamide families.

Abstract: Compositions may include those of the formula: (I) wherein R1 is an alkyl chain having a carbon number in the range of greater than 40 to 200, R2 is a multiester, R3 is hydrogen, an ion, or an alkyl chain having a carbon number in the range of 1 to 200, m is an integer selected from 0 to 4, and n is an integer selected from the range of 0 to 4, wherein the sum of m and n is 1 or greater. Compositions may include a reaction product of a polyisobutylene-substituted succinic anhydride and a hydroxy-functional dendrimer, wherein the molar ratio of polyisobutylene-substituted succinic anhydride to hydroxy-functional dendrimer is within the range of 10:1 to 30:1.
