A pH-neutral aqueous solution of a quinolonecarboxylic acid of the formula ##STR1## in which R.sup.1 represents halogen, C.sub.1-4 -alkyl or C.sub.2-4 -alkenyl,

pH-neutral aqueous solutions of quinolone-carboxylic acids

Known antibacterial quinolonecarboxylic acid derivatives such as ciprofloxacin are administered to animals in their food in the form of weak cation exchangers loaded therewith. The taste is much improved and the animals accept the material more readily.

Preparation and use of ion exchange resins loaded with

Improvement in the parenteral administration of a carboxylic acid of the formula ##STR1## in which X is N, C--H or C--F,

Basic formulations of quinolonecarboxylic acids

The invention relates to pesticidal (e.g. pyrethroid) pour-on formulations prepared on an aqueous basis; and also includes the method of combatting pests and parasites of warm-blooded animals, particularly acarines and insects by applying said pour-on formulations to the animals.

Pesticidal pour-on formulations particularly effective against acarines

A water-soluble pesticidal formulation approximately comprising in grams per liter 10 to 500 of at least one pyrethroid, 10 to 200 of a non-polar solvent having a solubility in water at 20.degree. C. of 0.01 to 15 g/liter, 20 to 500 of at least one non-ionic emulsifier, 5 to 250 of at least one anionic emulsifier, up to 300 of a solvent having a solubility in water at 20.degree. C. of at least 30 g/liter, up to 5 of a dyestuff, up to 50 of auxiliaries and up to 900 of water. The formulation will dissolve in water to give clear solutions.

Water-soluble pesticidal formulations

The invention relates to pesticidal formulations and their use, said pesticidal formulations consisting essentially of at least one pesticidal active pyrethroid compound and containing at least one surface active agent, water and, optionally, up to 40 parts by weight of a water-miscible solvent and up to 10 parts by weight of auxiliaries.
