This crisp, clean white bar smells of cold air and cool mint, and is just perfect for winter. It’s my first Christmas soap for 2014, and I’m not quite sure how it’s Christmas soaping season already.
This soap gets its whiteness from a combination of white kaolin clay (USA / Canada) and titanium dioxide. I’ve erred on the side of too little titanium dioxide to avoid the marbling effect you get when you add too much titanium dioxide to soap batter.
The final bars are hard, white, and smooth, making a great and original Christmas gift.
Per 500g (1.1lbs) of oils:
- 1 tbsp white kaolin clay (USA / Canada)
- 1 tsp titanium dioxide
- 10g cajeput essential oil
- 20g peppermint essential oil (USA / Canada)
Calculate with a 5% superfat.
Use SoapCalc to calculate your final amounts of oils, lye, and water based on the size of batch you want to make.
Follow my standard soap making instructions. I recommend soaping this recipe at room temperature to help prevent any glycerin rivers from the titanium dioxide. That means you should leave the oils and lye water to come to room temperature before combining, which is extra nice because it means you don’t have to juggle the two to try and get them to meet around 100°F.
Once you reach a medium trace (like pudding), blend in the clay, titanium dioxide, and essential oils. Bring the batter back to a medium thick trace.
Pour the batter into your prepared mould, tapping it on the counter to knock out any air bubbles. Use your spatula to create a bit of a drifting snow effect by dipping it into the soap and pulling it slightly forward as you pull the spatula out of the batter. Lightly insulate your mould and let saponify for 24 hours before slicing.
Let age for 3–4 weeks before using or gifting.
