Nevertheless Lomography at the moment actually offers it as "Colournegative Infraredfilm"
(At least in their German Version of their shop. Lomography do not let me access another language version.)
Oh that's strange, on the American version it specifically says that it's a color negative film and that they've duplicated the look of color infrared but they've done this by changing the response to the different dye couplers so that for example green turns out to look purple, but it's only a trick of the chemistry, not that it's actually picking up infrared light.
