Lavender Mint Cold process soap with double layer and in the pot swirl techniques

I am creating two layers, one solid layer and one top layer that use the in-the-pot swirl technique to create elegant, two layers and unique designs in each soap. This method is great because it can be used with a thick trace as well as with a thin trace. If you have a thin trace, simply mix a bit longer to get to the right consistency for pouring. I’m thrilled with how well the fragrance behaved during the process, just perfect for both pours.

I love how the purple layer gives the soap a simple base for the top swirls. For these soaps, I decided to keep the top layer simple as well and only use a lovely minty green color mixed with the natural color of the soap.

In this DIY I used a lovely “I Dream of Purple” color mica from Mad Micas and a “Granny Smith Green” color mica from Wholesale Supplies Plus.

My favorite cold process soap additives

Two of my favorite cold process soap making additives are kaolin clay and colloidal oatmeal. I add them to almost all of my soaps because of the wonderful properties they add to the soaps.

Kaolin clay

Kaolin clay is a very gentle clay used in many cosmetics and face masks. It is not only gentle on the skin but it is also great for anchoring the scents in the soaps. I also think it gives a great slip to the soaps that make the soap super luxurious.

Colloidal oatmeal

Colloidal oatmeal is also used in several skin care products and is considered a skin protectant. It helps retain moisture on the skin. It is very soothing and is usually recommended for people with dry skin. You can skip it but I like it in my soaps because of its excellent skin properties.

Another additive that I tend to add to the soaps is tussah silk. I love how it makes the soap so much smoother and with a lovely silky glide.

The double layer and in the pot swirl techniques for cold process soaps are two easy techniques that when combined yield lovely beautiful soap designs. This soap design technique is one of my favorites, It is great to use when testing new scents and I don’t know how they will behave with my specific formulations. In general, I have an idea of the behavior based on the supplier’s notes. Since I like using multiple butters in my soap formulations, the fragrance oil can behave a bit differently and possibly accelerate faster than anticipated.
