The groundhog says spring will soon be here, and at Coop Coco, we’re totally on board! We can’t wait to fill our flower boxes with colourful blooms and fresh herbs, so we decided to make our March soap of the month with both herbs… and salt!
Reminiscent of the famous salted herbs originating in Quebec’s Lower Saint-Lawrence region, this fresh, exfoliating soap is great for normal or oily skin. It lathers well and cleans deeply. Use it to wash your hands or body, and let its tangy scent of fresh herbs awaken your senses!
Before you begin
- Follow the safety precautions for using sodium hydroxide (lye)..
- Read the recipe all the way through to familiarize yourself with the steps.
- This recipe is calculated based on the amount of salt used, so it’s best not to change the basic oils, water, sodium hydroxide, salt, or superfatting oils. If you wish to make changes to the recipe, you can play with the colours and blend of essential oils.
- Don’t double or triple the recipe: the instructions take into account the time needed to pour the mixture into six individual moulds. If you increase the recipe, the mixture will be too thick to be poured into additional moulds.
- This soap is not recommended for people with dry or sensitive skin.
- 40 g Dead Sea Salt fine #1 without additives
- 10 g lime essential oil – Citrus aurantifolia
- 2 g sage essential oil – Salvia officinalis
- 1 g peppermint essential oil – Mentha piperita
- 1,4 g oregano essential oil – Origanum compactum
- 1,2 g basil essential oil – Ocimum basilicum
- 1 g ginger essential oil – Zingiber officinalis
- 0,5 g vetiver essential oil – Vetiveria zizanioides
- 7 g green clay
- 0,3 g green oxide
- 4 g dried mint
- 3 g zinc oxide
- Scales accurate to 1 g and 0.1 g
- 2 large stainless steel bowls
- 2 measuring cups (900 or 500 ml)
- 1 large pyrex cup or 1 HDPE pot for the sodium hydroxide mixture (more than 500 ml)
- 1 silicone mould with 6 round cavities
- 4 ramekins (for essential oils and other additions)
- Immersion blender
- 2 silicone spatula
- Protective gear
- Containers to make a double boiler
Good to know!
- Salt reduces lather, while coconut oil increases it. That’s why there’s so much coconut oil in this recipe. However, since too much coconut oil is drying, we’ve also added a high percentage of superfatting. For all these reasons, we advise you not to change the basic recipe.
- If you want to change the essential oil blend, remember that thyme, oregano, and ginger essential oils are dermocaustic (cause skin irritation) and their total should not exceed 0.5% of the soap recipe. So be sure not to exceed the total quantity of essential oils in our recipe, which is 14.3 g.
Steps to follow
1. Prepare the lye (measure, mix) and let cool. While it is cooling, measure all the other ingredients.
2. In the double boiler, melt the coconut oil. Once it is melted, add the olive oil and let cool.
3. In the double boiler, melt the shea butter and add the avocado (or tamanu) oil and the rosemary oleoresin. These are the superfatting oils.
4. In a measuring cup (ideally, 500 or 900 ml), mix the zinc oxide with 1 tablespoon of base oils. Set aside.
5. In a second cup, mix the green clay and green oxide with 1 tablespoon of base oils. Set aside.
6. Weigh the essential oils and mix them in a ramekin. Weigh the salt in one bowl and the dried mint leaves in another bowl.
7. Be sure everything is ready before mixing the base oils with the lye because you’ll have to work quickly.
8. When the base oils and the lye mixture have reached a temperature of between 25 and 35 degrees Celsius, pour the lye into the oil mixture and stir with an immersion blender until you reach light trace. Be careful! The coconut oil accelerates trace, so you’ll have to work quickly from now on.
9. Add the superfatting oils and the essential oils and mix again with the immersion blender.
10. Add the sea salt and mix with the silicone spatula.
11. Divide the mixture into two equal parts in the two measuring cups.
12. Add the herbs to the cup containing the zinc oxide.
13. Thoroughly mix the soap and colorants in the cups.
14. Hold one cup in each hand and simultaneously fill each of the mould cavities.
15. When all of the mixture has been poured, you can either leave the soap as is or lightly marble the two colours, swirling or making zigzags with the stem of the thermometer.
16. Cover for 24 hours, then unmold. Set aside to dry for 4 to 6 weeks. Use as a hand or body soap.
