I roll my own Castile soap. Recipes abound if you’re interested. All you need is olive oil and a bit of lye, cheaper in bulk of course. Follow the recipe, pour into cheap silicone molds of your choosing, wait. If you have enough molds and make a big batch, an hours work yields a year+ supply.

There’s another chemical I’m adding next, kinda expensive per gram, only takes a pinch per batch, supposed to harden it in days instead of weeks.

Best part is the bar lasts forever. Haven’t made any in awhile, but I’d forget how old the bar was when I finally replaced it. And that was without the hardening agent! Using Irish Spring, I’m clocking a bar a week.

Also, gets you really clean without feeling harsh or drying your skin. No idea how this voodoo works on a chemical level. But the fear of “lye” soap is a modern old-wives tale. Maybe it was harsh in great-grandma’s time? In any case, the lye is no longer lye after it all reacts.

PROTIP: There is a load of water in commercial bar soap. Step-mom would take it out of the waxy cardboard and leave it open in the cabinet. Dries out, lasts longer, feels no different. Takes months to dry enough to notice, buy ahead of time.
