Filling cosmetics bottles to the top: bad idea?
If I buy an empty plastic cosmetics bottle, it almost always has quite a lot more space than marked.
For ex, an empty plastic cosmetics bottle marked as for 30mL could be filled to 40mL and still had ~0.5cm-1cm space left.
Is it OK to fill almost to the top or is there any reason to leave so much space at the top?
My contents are not expected to ferment and create expansive air or such.

You fill it to the declared weight/volume on the front panel of the label, not visually. You can easily calculate a check weight. In Commercial manufacturing, we will perform check weights every X number of times for QC.

Net contents must be right per MAV - not under or overfill.
Don’t want product squeezed lout merely holding the bottle.
