Upon opening the tube, I see a small layer of oily liquid?
This phenomenon can occur sporadically and is called leaching.
It is not possible to predict for which product and from which assortment this may occur. This substance will always form at the top of the tube and will not mix with the content. It also does not affect the performance of the product in any way. So you can spray out 1 cm before use without the nozzle so that the layer is gone
