How to make Salt soap bars

Try our Pink Himalayan Salt bar recipe!

Salt is a crystalline mineral made of two elements, sodium (Na) and chlorine (Cl). Most of the world’s salt is harvested from salt mines or by evaporating seawater and other mineral-rich waters.

Salt Soap Benefits:

  • Moisturiser – Salt is a natural humectant, drawing moisture to skin and helping to retain it resulting in soft skin without skin being left feeling greasy.

  • Exfoliator – A gentle exfoliator to slough off dead skin cells and promote skin rejuvenation resulting in smoother softer skin.

  • Detoxifier - Salt is a natural detoxifier, as the salt absorbs the toxins from the skin.

Combine the cleansing, detoxifying and exfoliating qualities of a salt bath to your cold process soap recipe. The end result of the bar will be super-hard and it can produces a creamy lather.

Choose Your Salt

Himalayan Pink Salt

Pink Himalayan salt is made from rock crystals of salt that have been mined from areas close to the Himalayas, often in Pakistan and from the Khewra Salt Mine, the second largest salt mine in the world.

Himalayan salt contains traces of iron oxide (rust), which give it a rosy hue and also a small amount of calcium, iron, potassium and magnesium , making it slightly lower in sodium than regular table salt.

Sea Salt

Sea salt is made by evaporating seawater.

Like table salt, it is mostly just sodium chloride. However, depending on its source and how it was processed, it usually contains various trace minerals like potassium, iron and zinc.

The darker the sea salt, the higher its concentration of impurities and trace nutrients. However, due to ocean pollution, sea salt can also harbor trace amounts of heavy metals like lead.

Kosher Salt

Kosher salt has a large grain size.

The main difference between regular salt and kosher salt is the structure of the flakes. With the large grain size, it can sometimes be a bit harsh on the skin but will result in a deep exfoliating soap.

Precaution when using Salt:

The salt soap will start to harden almost immediately. If you're using a log mold, cut the soap as soon as it's firm enough. The soap will still be warm even as it's going through the saponification process. However, if you wait too long, the soap will be hard, difficult to cut, and result in crumbly bars.


If you don't like the exfoliating feeling of a salt, you can also brine the soap in water and add it to your lye solution.

Salt bar is great for oily skin.
