Soleseife Soap Recipe – German Brine Soap

soleseife soap recipeA few months ago, a “new” kind of German brine soap was all the rage on soap making forums, so of course I had to try it out, too. It was called soleseife (zo•luh zigh•fuh). People spelled it all different ways and many were mistakenly treating this soap like a regular salt bar, even though the outcome is very different. Soleseife is different, because the salt is dissolved in the water instead of stirred into the soap batter; so you get the benefits of bathing with saltwater without the exfoliating dimension of using undissolved salt. I think salt is too scratchy for soap, and prefer sugar scrub bars instead, but I was intrigued by the idea of a different kind of spa bar.

I developed my own soleseife soap recipe after dissecting two others that I found online:

Both of these seemed just like any other soap recipe, except for the sea salt mixed into the water and that the coconut oil was on the higher end, at 25-30% (my usual recipe is only 15%). Saltwater and sea salt soaps tend to have less lather, so that is why these recipes have more coconut oil. I couldn’t find any resource that told me how to know how much salt to use, so I just did some math to figure it out. If you divide the ounces of salt by the ounces of water, both of the above recipes used what came to 25% of their water amount for salt concentration. So that is what I went with, also. By the way, don’t try to do this soap recipe using the hot process method. The salt in the water causes it to dry out and harden up very quickly, so the results are unattractive. I used cavity molds for my soleseife soaps.

Soleseife Soap Recipe

Yield: 36 oz (oils)

  • 9 oz Olive Oil (25%)
  • 9 oz Coconut Oil (25%)
  • 5.4 oz Avocado oil (15%)
  • 4.7 oz Shea butter (13%)
  • 5.4 oz canola oil (15%)
  • 2.5 oz castor oil (7%)
  • 2 T goat milk powder (not required)

Lye solution:

Fragrance:

  • 2.25 oz essential or fragrance oil

I scented mine with a mix of peppermint, lavender, tea tree and Himalayan cedarwood essential oils; and as you can see, it turned out very white. It was fun to try a soap recipe from another country – I wish they were easier to find! While I’ve only made this recipe twice, I have started using brine water in my Dead Sea Mud Facial Bar recipe – I use a lot less salt, just over 3% for this purpose, but my skin absolutely loves it.

Have you made soleseife soap? What did you think? Do you have another favorite recipe from another country?
