COMPOSITIONS FOR TOPICAL APPLICATION TO ANIMALS TO CONTROL ENDOPARASITES

摘要

The invention concerns a pour-on composition for topical application to animals to control endoparasites. The composition comprises an endoparasiticide and a carrier comprising at least one saturated aliphatic carboxylate ester of a mono-alkyl ether of a mono- or poly- alkylene glycol. The compositions show surprisingly improved efficacy and freedom from unacceptable skin reaction even when applied to sensitive breeds of animals. In further embodiments the invention provides a process for the treatment of animals to control or eradicate endoparasites and a process for preparing endoparasiticidal compositions.
