Beer Soap│Cold Process soap

Not long ago, some friends came over to my house. After a small home party, I had some leftover beer, so I decided to make soap with it.

You might be wondering, "Soap made with beer?" Surprisingly, beer foam baths are actually a well-known skincare treatment that is said to have been enjoyed by Cleopatra herself.

Besides, whenever I open a can of beer, I rarely finish it. So I collect the leftover beer, pour it into a pot, boil it to remove the alcohol, and then use it to make soap.

This time, I used the Shower Technique to create a layered soap.

Unfortunately, the colors didn't turn out as clean and vibrant as I had hoped. I used too little yellow clay (loess powder), so the color wasn't as strong as I wanted.

This was also my first soap-making project after returning from an overseas business trip. I guess I wasn't fully focused yet. It reminded me that I should spend more time refining my recipes and paying closer attention to every step.

⚠️ Safety Precautions Before Making Soap
Caustic soda (lye) is a highly alkaline substance. Always work in a well-ventilated area and wear gloves, safety goggles, and a mask to prevent chemical burns.
Always add the caustic soda to the liquid, never the other way around. Reversing the order may cause the mixture to splash and result in serious burns.
If you use breast milk or other dairy products, monitor the temperature carefully after mixing with lye to ensure it does not exceed 40°C (104°F).
Fresh soap batter is still highly alkaline. Never touch it with bare hands.
Newly made soap is not ready for immediate use. Allow it to cure for approximately 6–7 weeks in a cool, well-ventilated place away from direct sunlight before using it.
