Abstract
A slurry composition that includes (A) a solvent, (B) a suspension aid, (D) an alkoxylated fatty amine, (E) an active ingredient, and optionally (C) a polar activator. The slurry composition may be formulated with up to 75 wt. % of the active ingredient (E), based on a total weight of the slurry composition, and remain as a pumpable and stable suspension. A concentrated slurry base is also disclosed which includes the solvent (A), the suspension aid (B), the polar activator (C), and the alkoxylated fatty amine (D), all being present at a higher concentration in the concentrated slurry base than a slurry composition made therefrom. A method of treating a subterranean formation is also disclosed, whereby the slurry composition is mixed with an aqueous fluid to form a treatment fluid, and the treatment fluid is introduced through a wellbore penetrating the subterranean formation.
