After receiving a few requests, I decided to try my hand at spa bars. Spa bars generally use only coconut oil for the entire oil content of the bars and have an equal oil to salt ratio (1:1).
Sea salt contains skin nourishing minerals such as magnesium, zinc, calcium, potassium and iodine. Some of the many benefits include:
- cleanses and detoxifies face and body
- sea salts draw toxins out of the body, which will naturally lead to feeling refreshed
- grainy and therefore makes for a great scrub
- increases blood circulation
The traditional recipe for spa bars (sea salt soap) is:
Coconut Oil = 100% of oil
Salt = 1:1 ratio with oil.
For example, if you were making a 3lb (48 oz) batch of cold process soap, the recipe would be as follows:76 degree Coconut Oil - 48oz
Water (by weight) - 18oz
Lye (aka, sodium hydroxide, caustic soda) - 8.61oz
Sea salt (by weight) - 48oz *add at trace after adding color and scent
I am not a huge fan of this recipe. It's too crumbly and sets up too quickly. If you don't cut within an hour (while it's still pretty caustic) it becomes rock hard and very difficult to cut without crumbling. Additionally, it's a little too harsh for me. With that said, plenty of people use, enjoy and sell these spa bars. They do have TONS of lather.
I've read not to use dead sea salt in soaps because it exaggerates the problems (too hard/crumbly) listed above. I've never actually tried dead sea salt in soap, so I cannot say first hand. I use fine grain sea salt. You can get it at From Nature With Love. They're having a 30% off sale on sea salt, so now is the time to buy.
This recipe is a little less harsh and easier to work with.Coconut Oil = 80%
Jojoba Oil = 20%
Salt (2/3 of oils)
For example, if you were making a 3lb (48 oz) batch of cold process soap, the recipe would be as follows:76 degree Coconut Oil - 38.4oz
Jojoba Oil - 9.6oz
Water (by weight) - 18oz
Lye (aka, sodium hydroxide, caustic soda) - 7.52oz
Sea salt (by weight) - 32oz *add at trace after adding color and scent
This one won't have as much lather as the last, but will be a little gentler. You should cut the bars between 2 and 2.5 hours after molded. It's best to cut while it's still a little warm. If you leave it overnight it will be too hard to cut.
In my opinion, lighter color sea salt bars are more appealing than darker colored ones. I think it's because the salt shows up better with lighter colors and really makes the bar stand out. I chose to make mine (pictured above) a light color (it's actually purple, but you can't tell in the photo) with a lavender and tangerine scent. I add a little more scent than usual (approx an extra ounce) because the soap gets pretty hot and can sweat out some of the scent.
