I was inspired to make a soap for Earth Day this year! It has actually been a couple of months since I’ve made a batch of soap! I’ve been working on a new Bath Bomb and Bubble Bar book so I’ve been elbow deep in baking soda, citric acid and SLSA! It was fun to get back to soaping.

This soap is colored using earth-inspired greens and blues and uses a simple drop swirl design. Here’s what I did!

Let’s make soap! If you are new to soapmaking, be sure to download our free guide, How to Make Cold Process Soap! Gear up in your gloves and your safety glasses.

Step 1: Make your lye solution. Weigh the water and lye into separate containers. Pour the lye into the water while stirring. Be sure to mix your lye solution in a well-ventilated area. Set aside to cool down.

Step 2: Weigh the hard oils/butters and melt, just until melted.

Step 3: Add the liquid oils to the melted hard oils/butters. Add the essential oil to the base oils.

Now, you should have your lye solution and base oils ready to go.

Step 4: Once the lye solution and oils have both cooled down to about 90-100 degrees F, pour the lye solution into your oils and mix to emulsion.

Step 5: Pour about 4 oz. of soap into five containers for coloring.

Step 6: Add one color to each cup and mix well using a mini mixer. I added some titanium dioxide to my base to color it white.

Step 7: Pour the base into your mold.

Step 8: Rotate through each colored soap three times, pouring into your base.

Step 9: Swirl the top of the soap, if you want!

Step 10: Allow the soap to saponify for 24 hours. Once hard, remove from the mold, cut and cure for 4-6 weeks.
