I used a few sprays on my tomcat and then brushed his fur with an ergonomic undercoat brush. This helped prevent the hair from flying everywhere and made brushing his longer fur much easier. The spray was quickly absorbed, so after brushing, the fur was no longer wet or shiny.
The list of ingredients is not complete on zooplus. It only mentions the preservatives methylisothiazolinone and butylisothiazolinone, both of which are highly allergenic (they are not allowed in leave-on hygiene/cosmetic products for humans).
