|A while ago, our blog team was asked to make a milk soap that was scented with Raspberry Fragrance Oil. This blog post covers my adventure while making this soap.
Collect needed items:
Measure fixed oils on your scale. Warm the fixed oils on the stove or in the microwave. I melted the oils in the microwave. Add sodium hydroxide to the water. Mix well. Weigh the Raspberry Fragrance Oil and set aside. Measure the milk and set aside.
Combine oils and lye solution. Mix until thin trace. Upon light trace, add the Raspberry Fragrance Oil, milk and color and mix well after each addition. Pour soap into the desired mold I used a different style of the Guerrilla Mold from Dirk’s post. Allow to sit until soap is firm.
The next morning cut into bars. Stack to allow good air circulation. Allow to cure for several days before using. Longer curing will result in a harder bar.
Other than my mold choice, this soap proceeded as expected. I knew that I was trying to obtain a raspberry colored soap, so I decided to use the Concentrated Liquid Purple Raspberry to color my soap. When I added my Raspberry Fragrance Oil to the raw soap, the raw soap turned a vibrant yellow color and I knew that coloring with a dye would not be possible. Sure as shootin’, the soap turned a pretty orange color and stayed that way all the way to the mold.
I made the batch again so I could try to color the soap a raspberry color and I used the Liquid Amethyst Pink Color instead. This time the soap turned an orange-ish pink in color.
After I poured both soaps into the mold, I set them aside and proceeded to make another batch of soap and then clean the kitchen. After I was finished cleaning the kitchen, I noticed that my second batch of Raspberry milk soap had separated. I grabbed my immersion blender and the whisk attachment for it. I blended it using the whisk until the soap was completely mixed. As the other soap looked fine, I left it alone.
After the soaps had set for 24 hours, I pulled them out of the molds and that was when I learned my first batch had separated as well. Grrrr! Oh well, at least this means that tomorrow I can show you how to re-batch a soap.
