Caroline, a very wise person said to me when I decided to be a short term rental host, "Don't put anything out there you are not prepared to lose!"
Guests will consider whatever is there is for their convenience, after all they are paying you good money for the privilege of using your facility, they expect value.
Make your listing appealing but....utilitarian, don't provide anything high end that they can remove.
I provide an electric bed for them with massage function but, they can't walk out the door with that!
I provide a cheese plate for every guest.......
But the cost of this is built into my listing amount on an averaging basis so, if a particular guest wants to take the lot with them, so be it, it doesn't happen often and I don't get upset about it.
Caroline, most guests are not going to remember you for your high end toiletries, they will just remember that toiletries were supplied but, opportunists will take advantage of you if you give them the chance.
If I was in your position I would provide literature stating that certain outstanding toiletry products are available to your Airbnb customers at a 10% discount but keep what you supply for guest use to the regular supermarket proprietary lines.....after all, that is all they are expecting!
