Do skincare sheet masks fall in the liquids category for carry ons?

I will be travelling from Amsterdam to Barcelona with only a carry on.

As a makeup/skincare loving person, I have currently already packed the max of 10 liquids (with a max of 100ml). However, I would also like to bring a facial mask, preferably to use in the plane or the night we land. The facial masks I use are sheet masks, which are kind of like wet wipes you put on your face for 15-20 minutes.

Now I now that wet wipes do not fall in the liquids category, but what about these face masks?

Some details:

• They are commercially packaged
• They are individually wrapped
• The sheet itself is moist
• The package will have some drops of excess liquid (cream or something alike) when you take the mask out.

I would prefer to find official rules on this. So far I can only find experiences of people in the US who said they just didn't present them to TSA as a liquid and were fine.
