Abstract
A liquid herbicidal composition is provided, comprising: a. 20 to 35 percent by weight, based on the total weight of the composition, of a water-soluble herbicidal ingredient; b. a C12-C16 alkyl ether sulfate; c. an organic solvent; and d. an alkyl polyglucoside. The composition is stable; i. e., it occurs in a substantially continuous, single phase at temperatures as low as −20° C. It also has a viscosity of no more than 2000 cps at temperatures as low as 0° C.
