Abstract: Described herein are compositions and methods for stabilizing the ability of hydrated polyacrylamide co-polymers to modify the physical properties of water solutions under high shear conditions. The compositions generally include a water solution including at least one hydrated polyacrylamide co-polymer; and at least one additive selected from the group consisting of i) a component having the formula of Formula 1, where Formula 1 is R1—O-EOa-POb-EOc—POd—R2, where R1 is hydrogen or any C1 to C18 carbon or carbon chain; O is oxygen, EOa is —(CH2CH2—O)a where a can be from 0-500; POb is —(CH(CH3)CH2—O)b where b can be from 0-70; EOc is —(CH2CH2—O)c where c can be from 0-150; POd is —CH(CH3)CH2—O)d where d is from 0-30; and R2 is hydrogen or any C1 to C18 carbon or carbon chain; ii) a tetra functional block copolymer; iii) a polyvinylpyrrolidone (PVP) homopolymer; and iv) any combination thereof.

Abstract: A liquid herbicidal composition free of alkyl polyglucoside includes glufosinate and/or a salt thereof, an alkyl ether sulfate or a salt thereof, a hydrotrope; a polycarboxylate having a weight average molecular weight ranging from greater than or equal to 1,000 g/mol to less than 70,000 g/mol, and water. The alkyl ether sulfate is according to the average formula (I): R—(OCH2CH2)n—OSO4 (I), wherein R is linear or branched alkyl group having from 8 to 18 carbon atoms and wherein the subscript n ranges from 1 to 10.
