[henry]

when I inj throught my Whatman filter in the sterile vial, i get some humidity inside near to the top. How I can avoid this?

Tell us how you're making it, not just the pieces you're having trouble with. What dissolving agent are you using - benzyl alcohol or BA and benzyl benzoate? Are you putting XX oil into the solution the heating before sterile filtering? You shouldn't be getting any water into the vial?!?

I used 'magic solution', don't know if BA or BB or both!
I bought it here!
I heated and filtered as usually we do. No water in the vial before filtering

As for the moisture in your bottle.

Nothing in the ingredients to convert fina would have any actual water in it. If you have some residue forming at the top of your vial the one thing that it could be is that the co-solvent(magic) could be trying to evaporate due to an increased temperature of the solution.Heat aids in the rate of evaporation of many substances. In this case all you would have to do is shake the bottle to mix all the ingredients again.

Was the solution rather warm when you were filtering it into the vial?

WARM? IT IS VERY HOT!!
I ALREADY TRIED TO SHAKE THE VIAL, BUT HUMIDITY IS STILL PRESENT...
