Rosemary Lavender Cold Process


When it comes to making soap for friends, it’s common to find that not all scents are crowd favorites. However, reverting back to blends of two or three essential oils can often please a lot of people at once. Rosemary and Lavender? Yes please. We also decided to try out a fun natural colorant – tomato paste! Your friends will be sure to enjoy this beautiful soap. 🙂

 What You’ll Need:

22 oz Distilled Water
8.44 oz Sodium Hydroxide
5 oz Castor Oil
20 oz Coconut Oil
16 oz Olive Oil Pure
10 oz Rice Bran Oil
9 oz Shea Butter

2 oz Lavender 40/42 EO
1.5 oz Rosemary EO
2.5 tsp. Rose Clay (40 oz soap)
1.5 tsp. Alkanet Root (30 oz soap)
0.5 oz Tomato Paste (10 oz soap)
1.5 tsp. Sodium Lactate

5lb Wood Mold
5lb Silicone Liner
5lb Multi-Pour Sectioning Tool

**If you are not local, you can get all of this and more at Bramble Berry! They will ship directly to you!**



In small ramekins or dixie cups, measure out each natural colorant and add 1 tbsp. of any fixed oil. We used sunflower oil. Mix using Bramble Berry’s mini mixer and set aside. You do not need to mix the tomato paste with a fixed oil, this one you can weigh out and just set aside.

We also drew a line on each glass container to show exactly where we needed to pour our soap to. On one container, we made a line at 30 oz and another at 10 oz.. There will be 40 oz left in your original container. This will make it easier to separate the soap batter out.

Weigh out 2 oz Lavender 40/42 EO and 1.5 oz Rosemary EO and set aside.


Separately weigh out the distilled water and lye into glass containers. As always, carefully add the lye to the water and gently stir with a stainless steel whisk until solution is clear. You can label and set aside, or you can put it into a designated freezer to cool down faster.

While the lye is cooling, weigh out all the oils in a large glass pyrex bowl and heat in the microwave until the oils are around 100 degrees.

Once the oils and lye solution are around 100 degrees (between 15 degrees of each other) you can now make your soap. Make sure you have gloves, goggles and long sleeves on while you are starting to make soap.

Put the stick blender into the oils and burp the blender so you avoid mixing in any air bubbles. Pour the lye solution down the arm of the stick blender and start mixing until you have reached a light trace.

Before you start soaping, assemble the 5lb multi-pour sectioning tool into the 5lb wooden mold. Be sure you have three sections.

1 2

Once you have reached a light trace, separate the soap batch out. Pour 30 oz into one of your containers, and 1o oz into another.


Mix in the colors into the following containers:
40 oz = Rose Clay
30 oz = Alkanet Root
10 oz = Tomato Paste

Mix in completely with a whisk or fork.


After the color is added, eyeball the fragrance oil into each container and mix in thoroughly.


Now you are ready to pour!

This is how we wanted the soap to look:


Pour the rose clay colored soap into all three sections so the batter is filled evenly across the sections.


We then poured the tomato paste soap into the far right section.


And last but not least, pour the alkanet root soap into the last two sections evenly.
Technically you don’t need the far left section, but it helps stabilize the center piece.


Carefully take out the sectioning tool and swirl with a skewer or another utensil.


Spray the top with 99% rubbing alcohol and insulate. These two things will help prevent soda ash and encourage gel phase.

After a few days, unmold and cut. Let the soap bars cure for 4-6 weeks before enjoying!


(The rippling in between the layers was due to thicker trace and can be prevented by soaping at a thinner trace.)


For the month of September, take 15% off all silicone molds!
