@Gina372 With all due respect, my suggestion re travel-size containers of things is not to use them at all. Single-use plastics are a serious problem on the planet, very environmentally unsound.
What many hosts do, and what works well, is to have smallish pump bottles of soap, shampoo, etc. and refill them between guests from a large bulk container. I got some nice liquid soap, which I have in the shower and by the sink, from Costco- the one I got is Beauty Soft brand body wash and hand soap, Milk and Honey. It has a mild, pleasant smell. That one might not be available in the US, as I got it at Costco Mexico, but I'm sure you can find something comparable.
Not only is it more economical and environmentally responsible to provide the amenities this way, it will cut down on the garbage you have to haul out when guests leave.
