|Recently, I was asked about making a high lanolin content soap that could be used as a wool wash bar for wool clothing. I’ve never made a high lanolin content soap before, so I decided this would be an opportune time for testing! After all, a single ounce is great for shaving. Two ounces seems extremely luxurious. Why not use more for wool? Who knows!
I decided to make a 1 pound test batch that was a variation of the typical MMS test batch.
Measure the fixed oils on your scale. Warm on the stove or in the microwave. I melted the fixed oils in the microwave. As this recipe has a high percentage of lanolin, a temperature sensitive ingredient, I didn’t want to overheat the fixed oils and ruin the soap. Lanolin has a melt point between 100 – 110 ° F. It is much easier to stir the fixed oils and gradually melt the lanolin in the same manner chocolate is melted.
Add sodium hydroxide to the water. Mix well. The temperatures were near 115 ° F. See the beginning of the blog on making Cold Process Soap to understand our thermometer-less method.
Combine the fixed oils and lye solution. Stir until thin trace. Stir well. Pour soap into molds. I used the Rubbermaid Drawer Organizers #2915. 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.
I made this batch of soap at the lower temperatures because the lanolin will increase the heat by itself and I did not want to deal with a soap volcano.
72 Hour Evaluation:
1) There was a small amount of dense lather.
Anyway, these are my evaluations. I hope this has helped you!
Would you make a wool wash soap bar?
