What is a sea salt soap bar?

Sea salt soap bars offer a blissfully natural way to cleanse and exfoliate your skin while evoking the calming essence of the sea. These bars gently scrub away dead skin cells, balance pH levels, and even reduce inflammation due to their anti-inflammatory properties.

Sea salt soap recipe

  1. In a well-ventilated area and while wearing safety gear, add water to a heat-resistant container.
  2. Slowly add lye to the water, stirring until fully dissolved. Be cautious of the rapid increase in temperature.
  3. Allow the lye water to cool while melting the coconut oil, almond oil, and castor oil in a saucepan over medium-low heat. Let both mixtures cool to around 100°F.
  4. In a large mixing bowl with tall sides, combine the melted oils and lye water mixture gradually using an immersion blender until it reaches a light trace.
  5. Add salt and mica powder, stirring well. Note that the trace will continue to thicken.
  6. Pour the soap into prepared soap molds and let them harden for 24 to 72 hours before removing. Place the bars on their ends with some space between them and allow them to cure for five weeks.
  7. After the curing period, your sea salt soap bars will be ready to use. Trust us, the wait is worth it!

Safety precautions

While creating your homemade sea salt soap bars, it's important to prioritize safety. Here are some tips to ensure a safe soap-making experience:

  • Wear protective gear, such as gloves and goggles, when handling the lye and the soap mixture. Sea salt can also cause irritation for certain skin types, so it's best to take precautions.
  • Clean and sanitize all soap-making utensils before and after each use to prevent contamination.
  • Be mindful of potential dryness when using sea salt soap regularly. If you experience excessive dryness, consider alternating with other moisturizing soaps.
  • Keep homemade sea salt soap bars away from children and pets. Additionally, store them in a dry place to extend their shelf life.

Frequently asked questions

Can I add fragrance? Absolutely! Add up to 40 drops of essential oils at a light trace before incorporating the colorant and sea salt.

Can I adjust the superfat %? Certainly! A higher superfat will make the bar more moisturizing, counteracting the natural drying properties of salt. Use a soap calculator to readjust the ingredients accordingly.

Do all soap bars have lye? Yes, soap bars are made with lye. However, there are melt-and-pour recipes available that eliminate the need for handling lye directly. These recipes allow you to focus on adding finishing touches to pre-made soap bases.

How do I check the trace? Checking for trace is easy. As the soap thickens with the immersion blender, hold it above the bowl and let the excess soap drip off. If it pools up on top of the soap in the bowl, you have achieved a trace.

Can I use regular kitchen utensils for making soap? No, it's not recommended to mix soap-making and cooking utensils. Store all soap-making materials separately, especially the container used for lye water.
