A simple recipe for a classical soap – a natural homemade lavender soap! A very foamy, creamy, and lightly scented soap with lavender that also has floral notes like rose and ylang ylang.

What’s So Good About Lavender

Lavender is well known for its two specific traits: its fragrance and its color. It’s filled with memories from the early XX century. If you stayed in a nice European hotel, your room had crisp linens scented with lavender. For someone else, lavender may bring to mind a grandmother who used a sachet  of lavender to freshen a dresser drawer.

The lavender flower and the oil derived from it have long histories in herbal medicine. Its name derives from the Latin root “lavare,” which literally means “to wash.”The earliest recorded use of lavender dates back to ancient Egypt. There, lavender oil played a role in the mummification process.  

During later times, lavender became a bath additive in several regions, including Persia, ancient Greece, and Rome. These cultures believed that lavender helped purify the body and mind.

Clinical studies in both animals and humans have shown the plant to have calming effects, reducing anxiety and helping to bring on sleep. The key ingredient is linalool, an alcohol component of lavender odor (this is also an allergen, so be careful if you are sensitive to it).

Still, the best from lavender it’s its fresh, floral, slightly wooden scent. And the fact that its pretty purple flowers are very fragrant and can be used as air fresheners in your home by themselves. They always remind me of being in a garden.

Recipe Ingredients

This recipe uses a mix of oils that make for a very foamy and creamy soap: olive oil, coconut oil, palm oil (RSPO) and sunflower oil. 

It uses an essential oil blend that smells mostly of lavender but has some floral notes, namely, the very appreciated geranium rose and ylang-ylang.

Get Ready!

  • Wear goggles and gloves! Look at “Safety Recommendations” in the video above or in How to Make Soap From Scratch
  • Watch the video above or read the post How To Make Soap by Cold Process Step-by-Step for instructions on cold process. These are generic steps for all recipes.
  • Assemble everything: ingredients, equipment, safety equipment. Prepare your workstations. Measure all the ingredients. Don’t start the recipe without having everything ready!
  • After measuring the oil, put a tablespoon of the measured oil into a small bowl. Add the violet mica with a bit of oil, mix well and put aside.

Heat the Oils

  • Heat the oils until the solid oils are completely melted (it is not necessary to heat all the time).

Make the Lye Water

Make the Soap Batter

  • Use as a target temperature 38ºC for the oil-solution mixture. If necessary, you can reheat the oils, but not the lye solution.
  • When adding the lye water to the oils, strain the water to avoid lye crystals in your soap batter.
  • Start mixing the soap batter with the immersion blender.
  • Add the oil with the colorant and mix well. Use the immersion blender to avoid clumps of colorant. Be careful not to reach heavy trace (creamy batter). If needed, use a whisker.
  • Add the extract and essential oil (s) after trace and stir with just a spoon. Lavender essential oil usually turns the soap batter from liquid to solid instantly, and this soap is heavy in hard oils. Be careful and be fast with next step.

Molding and Curing

  • Pour the dough into the silicone mold and sprinkle with alcohol or witch hazel.
  • Optional step – Pre-heat the oven with 40ºC. Turn it off then place the molds inside: the color will be brighter if the molds are heat insulated.
  • Wait 48 hours, keeping an eye on the hardness of the soap.
  • Let the bars cure for 4 to 6 weeks. See How To Cure Soap.

  1. Well, this is a recipe I will definitely love to try out. I love trying out new things, especially when it has to do with making something and cooking. Since the lavender is well know for it’s fragrance, then having a lavender soap to bathe with will definitely be nice. I can already imagine coming out of the bathroom and smelling so nice.

      Hello Nelson and thanks for your comment.

      Lavender soap and lavender scent are pretty nice 🙂 But I want to inform you that natural soap doesn’t leave a strong scent on the skin. That is done at the cost of several chemicals added to the soap – that would be a commercial soap. And that would also be a not so good soap in my opinion, as commercial soap is too drying and a bit aggressive to skin. Besides, soap is mainly made to wash 🙂

      Want to make a natural product to leave a nice scent on your skin? Make a natural lotion. I will be posting a few very very soon. Subscribe to HerbAlcochete mailing list to have the latest posts:
