Agrochemical concentrate comprising an adjuvant and a hydrotrope
Agrochemical concentrates having a continuous water-containing single phase, where said continuous phase also comprises an oil-based adjuvant and a hydrotrope capable of solubilizing said adjuvant in said continuous phase, a process for making these concentrates and a method of using these concentrates.
1. An agrochemical concentrate having a continuous water-containing phase, said continuous water-containing phase comprising an oil-based adjuvant and an anionic aliphatic carboxylate hydrotrope; where the oil-based adjuvant (i) is present at a concentration of from 10 to 60% by weight of the agrochemical concentrate and (ii) is selected from fatty alcohols, fatty acids or fatty amines and simple derivatives thereof; and a ratio of the oil-based adjuvant to the hydrotrope is from 1:10 to 10:1.
2. An agrochemical concentrate as claimed in claim 1 further comprising a second phase dispersed in the continuous water-containing phase.
3. An agrochemical concentrate as claimed in claim 2 where the second phase is a solid.
4. An agrochemical concentrate as claimed in claim 2 where the second phase comprises a water-immiscible liquid.
5. An agrochemical concentrate as claimed in claim 2 where the second phase is micro-encapsulated.
6. An agrochemical concentrate as claimed in claim 2 where the second phase is a micro-emulsion.
7. An agrochemical concentrate as claimed in claim 1 further comprising an agrochemical dissolved in the continuous water-containing phase.
8. An agrochemical concentrate as claimed in claim 2 where the second phase comprises an agrochemical.
9. A continuous oil phase in which is dispersed an agrochemical concentrate as claimed in claim 1 .
10. An agrochemical composition prepared by diluting an agrochemical concentrate as claimed in claim 1 in a spray-tank of water.
11. An agrochemical concentrate as claimed in claim 1 , wherein the hydrotrope is a potassium salt of 5(6)-carboxy-4-hexyl-2-cyclohexene-1 octanoic acid.
12. An agrochemical concentrate as claimed in claim 11 , wherein the oil-based adjuvant is oleyl alcohol.
13. An agrochemical concentrate as claimed in claim 1 , wherein the continuous water-containing phase further comprises a linear or branched mineral oil.
14. An agrochemical concentrate as claimed in claim 3 , further comprising a third phase comprising a water-immiscible liquid dispersed in the continuous water-containing phase.
15. An agrochemical concentrate as claimed in claim 3 , wherein the second phase comprises an agrochemical.
16. An agrochemical concentrate as claimed in claim 4 , wherein the second phase comprises an agrochemical.
17. An agrochemical concentrate as claimed in claim 5 , wherein the second phase comprises an agrochemical.
18. An agrochemical concentrate as claimed in claim 6 , wherein the second phase comprises an agrochemical.
19. An agrochemical concentrate having a continuous water-containing phase, said continuous water-containing phase comprising an oil-based adjuvant and an anionic aliphatic carboxylate hydrotrope capable of solubilising said adjuvant in said continuous water-containing phase, said concentrate further comprising (i) a second phase dispersed in the continuous water-containing phase where the second phase is a solid, and (ii) a third phase comprising a water-immiscible liquid dispersed in the continuous water-containing phase.
20. An agrochemical concentrate as claimed in claim 19 where the second phase comprises an agrochemical or the third phase comprises an agrochemical or both the second and third phases each comprise an agrochemical which may be the same or different agrochemicals.
