Let me be the first to say that I’m really surprised I haven’t made eucalyptus soap yet. First off, it smells wonderfully fresh and bright. Second, it’s super cheap, and the majority of my soaps are scented with the least expensive essential oils I can find, so I’m surprised I missed it until now. 100mL of Eucalyptus globulus essential oil isn’t even $5. Score! And, when combined with peppermint essential oil it gives you a bar of soap that’s a lovely thing to discover in your shower in the morning (you have shower soap elves too, right?).
I chose to colour the soap blue and green, using clay and some blue ultramarine. The shades I blended up really remind me of the Blue Mountains in Australia. Deep green trees, with a blue misty haze floating above them, blending into the sky. Sigh. I miss Australia.
The final bars are smooth, hard, and lovely. I decided to experiment with the addition of stearic acid for added hardness, but you’re welcome to simply use more lard or beef tallow if you don’t have any. The bars great for shaving (thanks to the clay), soaping, and shampooing. They’re bright and fresh, and they’ll give your nasal passages a hand if you happen to be a bit congested. Give them a try!
Peppermint & Eucalyptus Soap
20% olive oil (pomace)
20% soy bean oil (or olive oil (pomace))
25% refined coconut oil (USA / Canada)
15% unrefined shea butter (USA / Canada)
14% lard (or beef tallow)
5% castor oil (USA / Canada)
1% stearic acid (or round the lard up to 15%)
5% superfat (aka 5% lye discount)
Per 500g (1.1lbs) oils:
- 15g peppermint essential oil
- 15g eucalyptus globulus essential oil
- 1 tbsp dark French green clay
- ½ tsp blue ultramarine, divided
Calculate your recipe using SoapCalc to get your final, finite amounts of the fats, lye, and water.
Follow standard soap making procedure. I recommend letting the oils and fats come down to room temperature before combining as it gives you more time to work. At trace add the essential oils, the clay, and a small amount of the oxide (maybe 1/3 of the ½ tsp). Use an immersion blender to thoroughly blend the clay into the soap (otherwise you will have little clumps).
Pour half the soap into your mould.
Blend the remaining blue ultramarine into the remaining soap and pour that half into the mould. Swirl the two halves together using a spoon.
Let saponify for 24 hours before un-moulding and slicing. Let cure for a minimum of three weeks before using. Enjoy!
