This recipe for foaming hand soap is just one recipe that has become a staple in our house and in fact, I really didn't go in search of a recipe for hand soap originally. I had been creating and formulating a foaming body wash and just decided one day to alter the recipe a bit and try it in a foaming hand soap dispenser and viola! I've not looked back since.
Both this hand soap recipe and the body wash recipe (to post here soon) derive from a single concentrated base. I played around, adjusting the ingredients before landing on what works for my husband and I. And I don't share here until something new has been 'life' tested a good while, through a few seasons. Feel free to play around until you find the 'right mix' for you too.
It takes me 5 minutes to make up the concentrate that will last us 6 months or so... and keep in mind, I use the concentrate to make body wash too. It takes about 5 seconds to make the hand soap each time. I can't go to the store or even order it online in that amount of time! And cost? Well, again less than a penny per bottle. Just imagine for a minute how that might add up over a year's time. It's not the '1' bottle, it's that bottle at every sink, every time you refill it over the course of a year, 5 years, etc... It becomes considerable savings when you look at just this one thing over time. Yes, I could use Dr. Bronner's concentrate or even Dr. Bronner's bar soap but it would cost much more. Using Kirk's bar soap, I still get castile soap with the added benefit of changing fragrances with essentials oil at my whim for far less money. People are always asking where I get my essential oils. Various places but mostly Amazon. If you are in a hurry, many grocery stores with organic health and beauty product lines (Whole Foods, Harris Teeter, Lowes Foods, etc) also carry some essential oils. I use them in various ways every day and they last a long time...like years long.
1 bar Kirks Castile soap (all vegetable made with coconut oil)
8 cups boiling water
Put whole bar of soap in the microwave in a large microwave-safe bowl for 30 seconds , then grate soap through a cheese grater into the bowl. The microwaving helps soften it just enough to make grating easier and faster.
Add 8 cups boiling water to the grated soap. Stir until it dissolves. You may decide to put mixture back in microwave for a bit or just boil all ingredients on the stove in a pot but I've never had to do that. It seems to melt fine without bringing mixture to a boil.
Store in a container with lid for at least 1 week before preparing the Body Wash (so it has time to thicken, providing better foaming action).
Foaming Hand Soap Recipe
1 tsp Concentrate
10 oz water
10 oz Foaming Hand Soap Dispenser
2 to 3 drops essential oils of choice if desired
You will need a foaming hand soap dispenser. This allows you to use much less concentrate to get the same lathering effect from the soap. I purchased a bottle of foaming hand soap and used it until empty, then reused the bottle. If you have friends who aren't making their own and purchase new hand soap regularly, just ask them to save an empty bottle or two for you. Add one teaspoon of the concentrate to the bottle, add water and then your choice of essential oils for fragrance. You can leave out the essential oils but I love the soft, natural scent. Here's a few combinations I've tried:
Spring: 2 Drops Lavender and 1 Drop Jasmine
Summer: 3 Drops Lemongrass
Fall: 2 Drops Clove and 2 Drops Orange
Winter: 2 Drops Peppermint and 2 Drops Lavender
Have mercy upon me, O God, according to thy loving kindness: according unto the multitude of thy tender mercies blot out my transgressions. Wash me thoroughly from mine iniquity, and cleanse me from my sin. Psalm 51
(And Thanks, Krista, for asking me for this recipe.)
