Prepare your supplies and workspace by washing everything with soap and water. You can also sanitize your work area and tools with a few spritzes of alcohol.
Chop soap base. Chop your soap base into small cubes to speed up the melting process.
Melt soap. Place the soap cubes into a microwave-safe container or glass measuring cup. Melt in the microwave in 30-second intervals. Stir between each burst and be careful not to burn it.
Add oil and color. Add the argan oil and essential oils. Mix thoroughly until the oils are well incorporated. Add the rose clay or pink mica mixture slowly. Stir gently.
Pour soap bars. Place the soap mold on a cutting board or small tray, making lifting the mold easier. Next, spray the mold with a bit of alcohol. This helps the soap adhere better to the mold. Pour the liquid soap into the mold. Spritz the with alcohol to dissolve any bubbles.
Solidify. Leave the soap to set. It will take approximately 1 hour at room temperature or 30 minutes in the fridge.
Unmold. Once solidified, release the soap by gently pulling back the mold to break the airlock. Then pop each piece out of the mold.
Frost. Once fully hardened, remove the soap bars from the mold. Using a soft, flat brush, moisten the edges of the soap with a small amount of water. You want the rim barely moist, not dripping wet. Place the sugar in a shallow bowl. Then roll the moistened edges of the soap in the sugar to coat. Let dry for a couple of minutes. Now you can enjoy your wonderful frosted rose soap!
Package and store. Wrap your cinnamon soap bars tightly in plastic wrap to protect them from moisture. Enjoy!
