Abstract

The present invention relates to improved powderous formulations comprising organic acid amides having an aromatic ring system as well as to the production of such formulations.

First claim

The invention claimed is:

1. A powderous formulation comprising:
(i) 70-90 wt-%, based on the total weight of the powderous formulation, of at least one compound of formula (I):

 wherein
X is —N—; and
each of R 1 and R 2 is H, CH 3 , CH 2 CH 3 , (CH 2 ) 2 CH 3 or (CH 2 ) 3 CH 3 ; and

(ii) 10-30 wt-%) based on the total weight of the powderous formulation, of at least one auxiliary compound selected from the group consisting of ammonium dihydrogen phosphate, purified diatomaceous earth, potassium hydrogen carbonate, potassium sulphate, potassium carbonate, sodium chloride and sodium hydrogen carbonate, wherein
the powderous formulation has a minimum ignition energy (MIE) value of 10 mJ or greater.

2. The powderous formulation according to claim 1 , wherein each of R 1 and R 2 is H or CH 3 .

3. The powderous formulation according to claim 1 , wherein the compound of formula (I) is a compound of formula (Ia):

4. The powderous formulation according to claim 1 , wherein the compound of formula (I) is a compound of formula (Ia′):

5. The powderous formulation according to claim 1 , wherein the auxiliary compound has an average particle size (d 0.5) of 10 μm-100 μm.

6. The powderous formulation according to claim 1 , having MIE values of 10-100 mJ as determined by EN 13821:2002.

7. The powderous formulation according to claim 1 , wherein the formulation further comprises 0-5 wt-%, based on the total weight of the formulation, of water is present.

8. The powderous formulation according to claim 1 , which further comprise a carrier material selected from the group consisting of synthetically produced precipitated silicas, synthetically produced precipitated formates, proteins, starches, lignosulfonates and gums.

9. The powderous formulation according to claim 1 , consisting of:
(i) 70-90 wt-%, based on the total weight of the powderous formulation, of a compound according to formula (Ia):

(ii) 10-30 wt-%, based on the total weight of the powderous formulation, of the at least one auxiliary compound, and
(iii) 0-5 wt-%, based on the total weight of the powderous formulation, of water.

10. The powderous formulation according to claim 6 , having a MIE of 30-100 mJ.

11. Food products, feed products and personal care products comprising the powderous formulation according to claim 1 .
