“…Given that the use of antiparasitic collars is widespread in client-owned dogs, it was deemed necessary to ensure the compatibility of the LE contained in this novel collar product with the active ingredients found in commonly used antiparasitic collars. For this reason, the compatibility of the LE with imidacloprid/flumethrin (as found in Seresto ® , Elanco Animal Health, Greenfield, IN, USA) [ 25 , 26 , 27 , 28 ] and with deltamethrin (as found in Scalibor ® protector band, MSD Animal Health, Rahway, NJ, USA) [ 29 , 30 , 31 ] were assessed in order to account for any potential interactions. A mix containing 10% imidacloprid, 4.5% flumethrin, 2.5% LE Biosfeen ® , 2.0% lavender oil, and 81% 2-ethylhexyl diphenyl phosphate was prepared and, after stirring, stored in flasks for 2 weeks at 54 °C.…”
