Tutorial: Making Foaming Hand Soap

I always thought foaming hand soap was too fru-fru for me.  I had tried a few of my friends nice smelling foaming hand soap and thought I would give it a try.  Well, I didn’t like my hands smelling like flowery cucumbers, so it sat in my bathroom forever.

Having a baby changed my mind real quick on foaming soap.  It is a million times easier to use to wash his hands than bar soap or plain old liquid soap with a pump.  When my fru-fru foaming soap ran out this week I was dreading paying another $3.50 for SOAP.  I researched online and came up with a foaming hand soap recipe!

Ingredients:

1 Empty foaming handsoap dispenser
Water
Clear liquid handsoap

For this experiment I cleaned out the foaming dispenser until clear water ran through the pump.

I used a ratio of 1/5 liquid soap to 4/5 water.  This dispenser was 8.5 oz.  I guessed that the pump took up an 1/2 an ounce of space.  I divided 8 by 5 to get 1.6 ounces of soap.  Subtracting 1.6 from 8 I needed roughly 6.4 ounces of water.

Remove the pump and add the water to the empty bottle first.  Next pour in the liquid soap.  By adding the water first bubbles will be minimized.  Twist on the pump and shake gently to mix the soap into the water.  (NOTE: The pump was about 1/2 an ounce larger than I expected, ergo the excess spilled all over the counter.)

I used the same method to fill an ordinary liquid soap dispenser as a control.

The ordinary pump produced no foam, just watered down soap.

The foaming pump actually produced soapy foam!

The results side by side.

I washed my hands with the foaming soap and it worked like a charm.

Provided that you have an empty foaming soap dispenser, the cost of this recipe was rougly $0.30.  That’s a steal!

Things to remember:

1) Do not use moisturizing liquid soap.  It can clog up the pump.
2) The ratio of water and soap may vary depending on the pump style.  Use more or less until you find something that works.
3) If the pump gets clogged after a bit, pumping vinegar through the dispenser should clear it up.

I will report back in a month to see how the soap and dispenser held up.

Frugal tip of the day: Need I say it?  Make your own refills for pennies instead of buying a new bottle.

UPDATE:  I emptied out a little of the soap mix and added more liquid soap to the bottle.  The ratio is now probably 2/5 liquid soap and 3/5 water.  Upping the soap made a thicker foam and has not clogged up the pump yet.  I’ll report back in a while to see if this penny pinching idea is worth it!

    ummm… you may have inspired me to make my own peppermint scented soap… because 1. it was awesome but is now discontinued, 2. I wasted a ton of gas driving the weeks before xmas to a certain store that’s well known for it’s $3.50 soaps, and 3. they’re still available on ebay for 3/$12 PLUS shipping… so more than $5.00 a bottle! ouch!

    Do you think they have peppermint scent for soaps at craft stores?

      I have no idea about the craft stores, but I am looking for some lavender scent. I ran across a site that has the link to a store that has tons of scents – including “Downy” scent for when you make your own fabric softener! I will post the link when I find it again. I am curious to know if it will clog up the pump. If not, I am so going into the soap business!
