How to Make Perfect for Summer Lemonade Stand Cold Process Soap DIY

I am very excited to share this Lemonade Stand cold process soap DIY. For this DIY I decided to add some exfoliating properties and added a full tablespoon of ground walnut shells. This cold process soap formulation is a double butter formulation including shea butter and cocoa butter. I’ve also added avocado oil which is a fantastic oil for cold process soap making.

The cold process soap formulation I am sharing today is a double butter soap recipe/formulation. It does not contain palm oil. I use palm oil for some of my cold process soap formulations but I also know that some may want to avoid it for various reasons. I have both options of soaps available in my shop…. head over to check out your favorite.

Two of my favorite additives that I include in every batch of my cold process soaps are kaolin clay and colloidal oatmeal. I love how these additives make the soap feel very luxurious and silky. The kaolin clay helps anchor the scent and also adds a bit of hardness to the soap and makes it longer lasting. The colloidal oatmeal is known to have great properties for the skin and I just love the feel it gives to the soap. An additional additive I used for this soap is the ground walnut shells. This is a great way to add a bit of exfoliating action to the soap.

Additives

Kaolin clay

Ground walnut shells for soaps

I use Kaolin clay and colloidal oatmeal in most of my soaps at a ratio of on tablespoon per pound of oils.

Other Ingredients used

• Mica colorants (I used Guava Lava Mica for the pink and La La Mica for the yellow. Both these micas are from Mad Micas. I must say I really like working with these micas as they blend really well and the colors are gorgeous.)
• Fragrance – Lemonade Stand from BeScented. I had no issues working with this fragrance. It might have accelerated the batter a bit but not enough to create any issues for the design I had planned for this soap.

This recipe has a 7% superfat and a 2:1 water to lye ratio. My favorite lye calculator is soapcalc.net. Below is a snapshot of the recipe in soapcalc.

Lemonade Stand cold process soap making process

If you have never made soap before be aware that handcrafted soap uses lye. Lye is caustic and can burn your skin in contact. Before you try to make soap make sure to use the proper safety equipment. Use gloves, safety glasses, long sleeves, long pants and closed toe shoes.

Step by Step Cold Process soap making

1. Weigh and melt the oils and butters and set aside to cool approximately 85 degrees Fahrenheit. For this soap recipe I prefer soaping at around 80 to 85 degrees due to the high content of butters. This will prevent a false trace and will give you a bit more time to create swirls. I normally make soap with oils and lye water between 80 and 90 degrees Fahrenheit. I find that for my favorite formulations this temperature is just right.
2. Add the kaolin clay and colloidal oatmeal to the oils and mix well using an immersion blender.
3. Weigh out the water and NaOH (lye) in separate containers. Then add the lye to the water (never the other way around) and mix well until the lye is fully dissolved. Set aside until it cools down to 80 to 90 degrees in temperature.
4. Once the lye water solution and the oils have reached the soaping temperature add the lye solution to the oils.
5. Mix well with the immersion blender for a full minute to achieve a thin trace.
6. Add the fragrance oil and mix well.
7. Split a third of the batter and add the Guava Lava mica and one tablespoon of the ground walnut shells.
8. Pour this layer into the mold.
9. While the bottom layer is hardening separate the remaining batter into thirds and add the La La mica to one and titanium dioxide (for a white color) to the other remaining batter. Mix well.
10. The next layer is an in the pot swirl. All the white soap batter to the yellow soap batter at different places in the container. See video below for more details.
11. Pour the combined soap batter into the mold and allow the saponification process to take place. Cover if needed and keep in a place away from children and animals.

This recipe can be unmolded and cut after 24 hours. Allow the soap to cure for six to eight weeks and enjoy!
