Sodium Hydroxide - Is probably the only ingrdient not readily found in your kitchen cabinet. Sodium Hydroxide is a natural occuring alkaline substance that is required for the saponification process of turning water and oil into soap. When the process is complete there is no sodium hydroxide remaing in the product; there is only fresh traditionally made natural soap.
For those who are into soap ingredients, you may notice that
Palm Oil did not make the list.
While Palm oil is edible and makes a very good bar of soap there are environmental concerns around this product. As you read this large patches of rainforest are being burned down to make room for more Palm Trees to sell the oil. It's Ok, I think My Skin Harmony products are just fine without it.
