DIY: How to make pure castile soap?

This article will show you how to make your own castile soap bars. Buying natural or organic soap is very expensive today and unfortunately the healthy choice has become the expensive choice. And even if you are willing to pay the price for seemingly “natural products”, you will often find a long list of chemicals (non-natural additives) on the ingredient label on the back and think “what on earth is all this?”

I will advise you to never buy a product only judging from its name, because names these days are very deceptive (e.g. “herbal essence” which not only contains lots chemicals such as the carcinogen 1, 4-dioxane, which is known to cause cancer, but they also test on animals) and there is far between real natural products without chemicals inside.

This is what inspired me to make my own soap, deodorant, toothpaste, and cream. I simply couldn’t find products without chemicals – or rather I found very few (such as Miessence) but they are very expensive.


Does 100% non-chemical soap exist? No – Lye is always used

I wish there was such a thing as a completely natural soap made only from coconut oil, olive oil, essential oils etc. But this is unfortunately impossible. There is absolutely no way to make a bar soap without using lye.

The basic reaction that is needed to make soap, called ‘saponification’, cannot occur without some form of lye reacting with some form of oil. Lye is actually a general term for a very strong alkali. There are two alkali’s that can be used to make soap: sodium hydroxide (caustic soda) and potassium hydroxide. Both are considered lye, but the potassium hydroxide is not strong enough to make a solid soap. It is only used for making liquid soaps.
