Mineral Soap Ingredients

There are quite a few different mineral soap ingredients that can be incorporated into your homemade soap recipes to give them specific skin care benefits.

Charcoal, clays, pumice and sea salts all have special qualities that can be used to create unique soaps for many different applications.

Sea Salt

Mineral Soap Ingredients

Sea Salt when added to soap will produce a harder bar.

Varying amounts can be added at any stage of the soap making process.

A salt soap bar can be made using a high percentage of coconut oil and a large portion of sea salt (almost the same amount as oils). This soap also has a very high super-fat to compensate for the drying effects of the salt and high coconut oil.

The salt cuts down on lather so the large percentage of coconut oil balances out the formula.
