Soap from Hotel Soap

It’s still cold, so thought i’d take some time to turn old hotel soap bars into something luscious.  Allen’s Aunt June has taken people on tours all over the world and apparently collected soap along the way.  When i’m talking old soaps – theses babies are from the 70s and 80s! and there are hundreds and hundreds of them.  Needless to say, hotel soaps are seldom of the highest quality to begin with, but by now, their scents and oils were history.

However, the saponification was done, so, not wanting them to go to waste, i proceeded to get to work.

The Steps:

Unwrap each bar and break in half or fourths best you can.  Some will be too hard.

Place them in a food processor, maybe 1/3 full.  These will really be a challenge for your processor, so don’t overload it!  You can also grate them by hand.

Process them until flaky  – just takes a few seconds generally.

Then start the soap making process.

The beauty of using soap for the base, is that you do not have to have rubber gloves, goggles, and be careful to protect your skin from the intensely caustic effects of lye and lye water.  Also, none of the bringing the lye water to the right temperature and precisely the right time that you’ve brought the oils to the right temperature, then taking both items outside to carefully and slowly pour in the lye water whilst stirring.  Outside because of the extremely dangerous fumes put out by the lye water.  Lye water can easily melt holes in your clothes, and burn your skin and eyes.

Make Your Own Monday: Upcycling Hotel and Leftover Soap

that is absolutely well written for you to follow.  I highly recommend that you start with the 2 cups of soap flakes she recommends.  Stupid me, forgetting that it’s been 3 years (which makes me 3 years older) thought i could jump right in and did 10 cups.  That made for horrendous amount of mass to stir down.  My shoulder is sore the next evening from the stirring.

Nevertheless, i did get it done, then added 1 cup extra virgin olive oil, 2 cups coconut oil, 2 cups shea butter, and several drops of sweet orange essential oil.  Just a complete guess as to whether or not the logs would cure enough to cut.  But 24 hours later, i popped them out of the logs and they sliced nicely, though indeed, they are soft.  Now laid out to cure at about 4 weeks.

This project was spur of the moment, so first i had to thaw out my shea butter and warm the coconut oil to 76 degrees so it would be a liquid
This was my double boiler method.  Inside the top pot is the 10 cups of soap flakes.

One of three silicon soap molds from Essential Depot. These are SO handy, but you can use whatever you have on hand to dedicate to soapmaking.

All the bars are carefully cut and laid out to cure and harden.  Right now they are very soft.

  1. Hi Tauna…I grew up with my mother, my aunt & grandmother making soap.  So have watched that process many times.  What my Aunt Fern made was for laundry & we had the cleanest, whitest clothes around.  Still have a penny postcard with the lye soap recipe that Grandma Thomas sent to my mother in my mother’s recipe box.  It’s still in my kitchen to this day (60 years now).  Brought back many memories.
