Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
78 words
An insecticidal formulation which has a pronounced residual action and can be applied both to wet animals and to dry animals, containing (a) 0.1 to 20% by weight of a synthetic pyrethroid (b) 1 to 40% by weight of a water-soluble gel-forming or lacquer-forming polymer; (c) 40 to 98% by weight of an organic, water-miscible non-irritant solvent, in which the said polymer does not dissolve; and (d) 0.1 to 10% by weight of one or more further additives.
Claim 2
Dependent Claim
78 words
An insecticidal formulation which has a pronounced residual action and can be applied both to wet animals and to dry animals, containing (a) 0.1 to 20% by weight of a synthetic pyrethroid (b) 1 to 40% by weight of a water-soluble gel-forming or lacquer-forming polymer; (c) 40 to 98% by weight of an organic, water-miscible non-irritant solvent, in which the said polymer does not dissolve; and (d) 0.1 to 10% by weight of one or more further additives.
Claim 3
Dependent Claim
53 words
An insecticidal formulation according to claim 1, containing: (a) 0.1 to 5% by weight of the insecticidal active compound; (b) 1 to 20% by weight of the polymer; (c) 60 to 90% by weight of the organic, water-miscible solvent and (d) 0.1 to 10% by weight of the one or more further additives.
Claim 4
Dependent Claim
54 words
An insecticidal formulation according to claim 1 wherein the polymer of component (b) is sodium carboxymethylcellulose, polyacrylic acid, polymethacrylic acid or a salt thereof, sodium amylopectin semiglycolate, alginic acid or propylene glycol alginate as the sodium salt, gum arabic, xanthan gum, guar gum, a gelatin, methylcellulose, another non-ionic cellulose derivative or a soluble starch.
Claim 5
Dependent Claim
20 words
