In this video I show you how I make cold process pink himalayan sea salt soap bars.

I love salt soap, they exfoliate nicely, are very hard right out of the mold and the lather is really awesome when the soap is made with coconut oil.

Because salt inhibits lather I used 100% coconut oil in this recipe. Coconut oil is the only oil that lathers well in the presence of salt.

Coconut oil can be drying to the skin so I used a 20% superfat. I also didn’t add any extra lye even if I added citric acid to this recipe. Instead I just let the superfat be a little higher. Read more about citric acid in soap making below.

I calculate my soap recipes with this lye calculator: http://soapee.com/calculator

○ Cold process himalayan sea salt soap recipe:

400 g coconut oil (100%)
58.6 g lye (33% lye concentration)
117 g distilled water
200 g pink himalayan sea salt

Optional:
8 g citric acid
1 tsp pink clay
10 ml fragrance oil

Cure the soap for at least 4 weeks before using it on your skin.

○ Citric acid information

When citric acid and lye (NaOH) are combined, sodium citrate is created. Sodium citrate works as a chelator in soap.

A chelator traps metal ions such as calcium and magnesium that can be found in tap water.

These metal contaminants can cause rancidity and soap scum in handmade soap.

A chelator binds to these metals so that they can’t bind to the soap molecules. This way the soap won’t react with them and the soap's lather improves + shelf life increases.

Citric acid does not lower the pH of soap. Instead it consumes some of the lye and increases the superfat. Add 6 g extra lye for every 10 g of citric acid added to a soap recipe if you want to keep the superfat % at the same level.

How much citric acid should be added to soap?

Usage rate in bar soap is 1-2% of the oil weight.

How to use citric acid

Add citric acid to the distilled water and dissolve completely before adding the lye.
