Cut up the soap base into inch squares. Split the squares placing half of them into two different glass jars.
Add the dried lavender flowers on top of the soap base in one of the jars.
Add the dried rosemary leaves on top of the soap base in the other jars.
Heat in a double boiler for one to two hours on low heat. This will infuse the herbs into the soap base.
When done, strain each infused soap base into a different jar, keeping them separate.
If using the colourant, add the purple mica powder into the jug with the infused lavender in it and stir to combine. Add the lavender essential oil to this jug if using as well and mix through.
Leave the rosemary melted soap base white. Add the rosemary essential oil to this jug if using and mix through.
Take both measuring jugs and swirl them into the soap mould at the same time. Make sure to evenly swirl both colors to create the same design.
Just a note: If your soap has bubbles form on the top after you pour your soap base into your molds, you can spray the tops of the soap with rubbing alcohol (isopropyl alcohol) as this will help break them up and give you a smooth surface.
Let sit out overnight or until it is completely hard.
Essential oils are potent, and need to be diluted. As this soap is being used on your body, you will need to use essential oils that are gentle enough to be applied to your skin – and use in the correct quantities. Be careful to avoid sensitive areas like your eyes.
Be mindful of who will be using the soap when adding essential oils as some people can’t use some oils and some oils can’t be used on young children or pregnant and breastfeeding mothers. Some essential oils should not be used on children under 10. Do your research before adding and using any essential oils!
Don’t use on skin with open wounds or cuts.
Test on small area of skin before using. If there’s any irritation, dilute with more carrier oils.
