Question for german bees

[pablos]

There is a preparate named "H........K" claimed to be a mix between piperonal and cinnamalaldeyde. Have anyone experience with that?

Combinations of these two in alcoholic solution are used in the preparation of certain cosmetic products.

I wouldn't have a clue about the concentration though. It is pretty expensive too, last time I checked .

Then the black pepper route would probably be more practical.

easy to find out. Ask their customer service.
