In some parts of California, for example, waste disposal services might take them all and do the right thing.

Some cities might allow donation to shelters.

In no event should they go into the sewer or storm drain.

In most cases, however, it's probably best to dump them in a landfill, unless they are petroleum or solvent based, in which case they present a special hazard.

Good on you for wanting to know and wanting to recycle the containers, at least.

Although I would not have use for the cologne and aftershave, I would have no problem taking half-used shampoos, soaps, etc. Do you know anyone who is struggling financially? Every little bit helps when you have cash problems. It isn't like you are talking about half-eaten candy bars.

I don't know if homeless shelters or other crisis centers would take these or not. Some places, it would not be legal for them to take them. But it would be worth a call.

You could bring them and put them on a "give away" table, maybe, or else someone might know who to give them too--needy families. If they know where they are coming from they probably won't have a problem with it.
