Summer Scents – Midnight Waters Cold Process Soap DIY

This week’s cold process soap DIY is another one inspired by summer scents. I used this Midnight Waters fragrance oil in last week’s DIY and loved the scent so much that I decided I had to have it in soap as well. This Midnight Waters cold process soap was fun to make, and I hope you like the design. I was inspired by the name and wanted to create a fun ocean scene with midnight waves.

For this Midnight Waters cold process soap DIY, I am using the Brambleberry Midnight Waters fragrance oil that I’ve been wanting to use for a while. It is a lovely scent, perfect for summer projects. However, I think the scent is great for any time of the year. I am using the Midnight Blue mica from Nurture Soap and Activated Charcoal for the black swirl on the top layer.

The fragrance behavior notes indicate that the fragrance oil slightly accelerates and that it discolors to tan. I kept both into consideration when planning this soap. I increased the water to a 2:1 water to lye ratio and planned to use dark colors that can take some discoloration without too much impact.

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 fantastic 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.

For this Midnight Waters cold process soap, I decided to make a double layer and hanger swirl design. The bottom layer with the blue would be the lovely ocean, and the top layer with the activated charcoal, black swirls, the beautiful waves we see in the ocean at night.

This scent is really lovely, and I think the design with the double layer, the swirls, and the top waves makes the most beautiful soaps.
