SELF-EMULSIFYING OIL
A concentrate suitable for forming a stable aqueous composition upon dilution with water includes in one aspect a self-emulsifying oil comprising a modified vegetable oil which is modified with a moiety more polar than the vegetable oil and the polar moiety is attached by a covalent bond to the vegetable oil and an active ingredient.
1 . A concentrate comprising:
a self-emulsifying oil comprising a modified vegetable oil wherein said modified vegetable oil is modified by reacting vegetable oil with a moiety more polar than the vegetable oil wherein the polar moiety is attached by a covalent bond to the vegetable oil through an ene reaction; and
an active ingredient.
2 . A concentrate according to claim 1 wherein the polar moiety comprises maleic anhydride.
3 . A concentrate according to claim 1 wherein the vegetable oil comprises soybean oil.
4 . A concentrate according to claim 1 wherein the modified vegetable oil is neutralized with a base.
5 . A concentrate according to claim 4 wherein the base is aminomethyl propanol.
6 . A concentrate according to claim 1 wherein the active ingredient comprises a water-insoluble active organic compound.
7 . A concentrate according to claim 6 wherein the water-insoluble active organic compound is an agriculturally active chemical.
8 . A concentrate according to claim 7 wherein the agriculturally active chemical is a herbicide selected from the group consisting of phenoxy compounds, benzoic acid, acetic acid, phthalic acid, aniline derivatives, nitriles, amides, acetamides, anilides, carbamates, thiocarbamates, heterocyclic nitrogen derivatives, urea derivatives, and phosphates.
9 . A concentrate according to claim 1 which includes a cosolvent.
10 . A concentrate according to claim 9 wherein said solvent is fatty acid dimethylamides.
11 . A concentrate according to claim 1 wherein said active is selected from the group consisting of ametryn, propiconazole, propanil, tebuconazole and mixtures thereof.
12 . A concentrate according to claim 1 wherein said active is a non-acid-sensitive active ingredient.
13 . A concentrate according to claim 12 wherein said modified vegetable oil is neutralized with a base.
14 . An aqueous delivery system comprising the concentrate of claim 1 and water of dilution.
15 . A concentrate comprising:
a self-emulsifying oil comprising a modified vegetable oil wherein said modified vegetable oil is modified by reacting vegetable oil with a moiety more polar than the vegetable oil wherein the polar moiety is attached by a covalent bond to the vegetable oil; and
