Abstract

An emulsifiable concentrate comprising a high content of abamectin is provided. The concentrate includes an amide solvent of formula (I) and an alkyl lactate of formula (II):

wherein R 1 is C 5 -C 19 alkyl and R 2 is methyl, ethyl, propyl, butyl or a mixture thereof;

wherein R 3 is C 1 -C 16 alkyl. The concentrate optionally includes a surfactant. The concentrate exhibits very good low temperature stability and dilution stability. A method for preparing the concentrate; and an emulsion that can be obtained by mixing water, abamectin, the amide of formula (I) and the alkyl lactate of formula (II), is also provided.

First claim

The invention claimed is:

1 . An emulsifiable concentrate, comprising:
(1) abamectin in an amount of 5 wt. %-20 wt. %, based on the total weight of the concentrate; (2) an amide selected from the group consisting of N,N-dimethyl capramide, N,N-dimethyl octanamide, and N,N-dimethyl dodecylamide in an amount of 20 wt. %-60 wt. %, based on the total weight of the concentrate; and (3) an optional surfactant.

2 . The concentrate according to claim 1 , further including an alkyl lactate of formula (II):

wherein R 3 is C 1 -C 16 alkyl; and
wherein the alkyl lactate of formula (II) is present in an amount of 5 wt. %-55 wt. %, based on the total weight of the concentrate.

3 . The concentrate according to claim 2 , wherein R 3 in formula (II) is C 1 -C 8 alkyl.

4 . The concentrate according to claim 1 , wherein the optional surfactant is present in an amount of 1 wt. %-30 wt. %, based on the total weight of the concentrate.

5 . The concentrate according to claim 4 , wherein the optional surfactant is present in an amount of 5 wt. %-20 wt. %, based on the total weight of the concentrate.

6 . The concentrate according to claim 1 , wherein the optional surfactant is present, and the optional surfactant is an anionic surfactant selected from the group consisting of: alkali metals, alkaline earth metals or ammonium salts of sulfonic acid, sulfuric acid, phosphoric acid, and carboxylic acid, and mixtures thereof.

7 . The concentrate according to claim 1 , wherein the optional surfactant is present, and the optional surfactant is a nonionic surfactant selected from the group consisting of: alkoxylates, N-substituted fatty acid amides, amine oxides, esters, glycosyl surfactants, polymeric surfactants and mixtures thereof.

8 . The concentrate according to claim 1 , wherein the optional surfactant is present, and the optional surfactant is a cationic surfactant selected from the group consisting of: quaternary ammonium compounds having 1 or 2 hydrophobic groups, and salts of primary amines.

9 . The concentrate according to claim 1 , wherein the optional surfactant is present, and the optional surfactant is selected from the group consisting of: amphoteric surfactants, block polymers, and polyelectrolytes.

10 . A method for preparing the concentrate according to claim 1 by mixing the abamectin, the amide, and the optional surfactant.

11 . An emulsion obtained by mixing water with the concentrate according to claim 1 .

12 . An emulsifiable concentrate, comprising:
(1) abamectin in an amount of 5 wt. %-20 wt. %, based on the total weight of the concentrate; (2) an alkyl lactate selected from the group consisting of: methyl lactate, ethyl lactate, and butyl lactate in an amount of 25 wt. %-40 wt. %, based on the total weight of the concentrate; and (3) an optional surfactant.

13 . The concentrate according to claim 1 , wherein the abamectin is present in an amount of 10 wt. %-20 wt. %, based on the total weight of the concentrate.

14 . The concentrate of claim 2 , wherein the alkyl lactate of formula (II) is present in an amount of 10 wt. %-50 wt. %, based on the total weight of the concentrate.

15 . The concentrate of claim 12 , wherein the abamectin is present in an amount of 10 wt. %-20 wt. %, based on the total weight of the concentrate.
