Surfactants for agricultural products
Agricultural products, such as pesticides, plant growth regulators, fungicides, herbicides, and insecticides, may be formulated to include one or more surfactants, from one or more surfactant classes, such as derivatives of amino acids that have surface-active properties.
1 . A formulation for a pesticide, comprising:
at least one surfactant of Formula I,
wherein R 1 and R 2 may be the same or different, and may be selected from the group consisting of hydrogen and C 1 -C 6 alkyl, wherein the C 1 -C 6 alkyl may optionally be substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;
n is an integer from 2 to 5 (including 2 and 5);
m is an integer from 9 to 20 (including 9 and 20);
the terminal nitrogen is optionally further substituted with R 3 , wherein R 3 is selected from the group consisting of hydrogen, oxygen, hydroxyl, and C 1 -C 6 alkyl, wherein the C 1 -C 6 alkyl may optionally be substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;
an optional counterion associated with the compound which, if present, is hydroxide; and
a pesticide.
2 . The formulation of claim 1 , further comprising a water-insoluble solvent.
3 . The formulation of claim 1 , wherein the surfactant comprises at least one of
dodecyl 6-(dimethylamino)hexanoate N-oxide, having the following formula:
4-((6-(dodecyloxy)-6-oxohexyl)dimethylammonio)butane-1-sulfonate, having the following formula:
and combinations thereof.
4 . The formulation of claim 1 , wherein the pesticide is an insecticide.
5 . The formulation of claim 4 , further comprising an antifoaming agent.
6 . The formulation of claim 4 , further comprising an antifreezing agent.
7 . The formulation of claim 4 , further comprising water.
8 . The formulation of claim 4 , wherein the surfactant comprises at least one of
dodecyl 6-(dimethylamino)hexanoate N-oxide, having the following formula:
4-((6-(dodecyloxy)-6-oxohexyl)dimethylammonio)butane-1-sulfonate, having the following formula:
and combinations thereof.
9 . A formulation for a fungicide, comprising:
at least one surfactant of Formula I,
wherein R 1 and R 2 may be the same or different, and may be selected from the group consisting of hydrogen and C 1 -C 6 alkyl, wherein the C 1 -C 6 alkyl may optionally be substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;
n is an integer from 2 to 5 (including 2 and 5);
m is an integer from 9 to 20 (including 9 and 20);
the terminal nitrogen is optionally further substituted with R 3 , wherein R 3 is selected from the group consisting of hydrogen, oxygen, hydroxyl, and C 1 -C 6 alkyl, wherein the C 1 -C 6 alkyl may optionally be substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;
an optional counterion associated with the compound which, if present, is hydroxide; and
a fungicide.
10 . The formulation of claim 9 , further comprising a co-surfactant.
11 . The formulation of claim 9 , further comprising a carrier agent.
12 . The formulation of claim 9 , wherein the surfactant comprises at least one of
dodecyl 6-(dimethylamino)hexanoate N-oxide, having the following formula:
4-((6-(dodecyloxy)-6-oxohexyl)dimethylammonio)butane-1-sulfonate, having the following formula:
and combinations thereof.
13 . A formulation for an herbicide, comprising:
at least one surfactant of Formula I,
wherein R 1 and R 2 may be the same or different, and may be selected from the group consisting of hydrogen and C 1 -C 6 alkyl, wherein the C 1 -C 6 alkyl may optionally be substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;
n is an integer from 2 to 5 (including 2 and 5);
m is an integer from 9 to 20 (including 9 and 20);
the terminal nitrogen is optionally further substituted with R 3 , wherein R 3 is selected from the group consisting of hydrogen, oxygen, hydroxyl, and C 1 -C 6 alkyl, wherein the C 1 -C 6 alkyl may optionally be substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;
an optional counterion associated with the compound which, if present, is hydroxide; and
an herbicide.
14 . The formulation of claim 13 , further comprising a second herbicide.
