Combination product for controlling parasites on animals
View Patent ↗The invention relates to novel compositions for controlling parasites on animals, comprising an N-arylpyrazole and also a pyrethroid in a formulation comprising aliphatic cyclic carbonates and aliphatic cyclic or acyclic polyethers.
1. A composition for controlling parasites on animals, comprising:
a. fipronil;
b. phenothrin;
c. an aliphatic cyclic carbonate; and
d. an aliphatic cyclic or acyclic polyether.
2. The composition of claim 1 , further comprising an ester of a dihydric or trihydric alcohol having up to three carbon atoms with organic fatty acids having 6 to 18 carbon atoms.
3. The composition of claim 1 , wherein the fipronil is present in an amount of from 1 to 27.5% by weight of the composition.
4. The composition of claim 1 , wherein the aliphatic cyclic carbonate is present in an amount of from 10 to 70% by weight of the composition.
5. The composition of claim 1 , wherein the aliphatic cyclic or acyclic polyether is present in an amount of from 20 to 77.5% by weight of the composition.
6. The composition of claim 1 , wherein the fipronil is present in an amount of from 7.5 to 15% by weight of the composition.
7. The composition of claim 1 , wherein the cyclic carbonate is selected from the group consisting of ethylene carbonate, propylene carbonate, and mixtures thereof.
8. The composition of claim 1 , wherein the aliphatic cyclic carbonate is present in an amount of from 15 to 40% by weight of the composition.
9. The composition of claim 1 , wherein the aliphatic cyclic or acyclic polyether is selected from the group consisting of diethylene glycolmonoethyl ether, diethylene glycol monopropyl ether, dipropylene glycol monopropyl ether, and tetrahydrofurfuryl alcohol.
10. A composition for controlling ticks on dogs, comprising:
a. fipronil;
b. phenothrin;
c. propylene carbonate; and
d. dipropylene glycol monomethyl ether.
11. A method of controlling ticks on an animal, which comprises applying to said animal an effective amount of the composition of claim 10 .
12. The composition of claim 1 , wherein the phenothrin is present in an amount of from 20 to 70% by weight of the composition.
13. The composition of claim 10 , wherein the phenothrin is present in an amount of from 20 to 70% by weight of the composition.
