Stable, concentrated herbicidal compositions
View Patent ↗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 C 12 -C 16 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.
1. The liquid herbicidal composition comprising the elements (a-g) are present as:
a) 44% glufosinate 50%;
b) 38% sodium lauryl ether sulfate;
c) 7% tetrahydrofurfuryl alcohol and 3% isopropanol;
d) 5% linear hexyl polyglycoside;
e) 1% ethoxylated trisiloxane;
f) 1.75% sodium xylene sulfonate 40% aqueous; and
g) 0.25% a mixture of perfluorinated phosphinic acid and phosphonic acid defoamer.
