Where in the UK can i buy Concept for you carp fishing bait powder additive called Super Slimy?

It is a powder bait attractant that you coat boilies, tiger nuts, anything you want to use as a bait when carp fishing which when left in the water it covers the bait in a slimy coating attractant which lasts for hours? I know the firm is german and their website dosent help for any uk stuff at all. Cheers!
