What Is Glycerin Soap?
Glycerin soap is a type of soap that contains high levels of glycerin—a humectant that draws moisture into the skin. It’s known for its clarity, gentle cleansing, and skin-softening properties. Glycerin is a natural byproduct of the saponification process, but in commercial soap, it’s often removed. Not here! Glycerin soap keeps that moisturizing magic intact.
It’s especially beneficial for people with dry or sensitive skin, and because it’s so mild, it’s often used in facial bars, baby soaps, and artisan products.
Why Choose Glycerin Soap?
Glycerin soap offers a lot more than just good looks:
-
Gentle on Skin: Perfect for sensitive or dry skin types.
-
Customizable: You can add essential oils, herbs, colors, and even embed items like loofahs or flower petals.
-
No Lye Handling: Most glycerin soap is made with melt-and-pour bases, so you skip the dangerous part of soap making.
-
Quick and Easy: No long cure time—your soap is ready to use as soon as it hardens.

Rubbing alcohol in a spray bottle (to remove bubbles)

How to Make Glycerin Soap at Home
Step 1: Cut and Melt the Soap Base
Start by chopping your glycerin soap base into small cubes. This helps it melt evenly. Place the cubes in a microwave-safe measuring cup or a double boiler. Heat in 30-second intervals in the microwave, stirring between bursts, until fully melted. Avoid boiling it—just get it to a smooth, pourable consistency.
Step 2: Add Color and Fragrance
Once the soap is melted, add a few drops of soap-safe colorant and essential oil. Stir gently but thoroughly. A good rule of thumb is about 1 teaspoon of essential oil per pound of soap base. Don’t overdo it—some oils can irritate the skin in high amounts.
Step 3: Add Decorative Touches (Optional)
Now’s the time to add dried flowers, herbs, or exfoliants like oatmeal or poppy seeds. You can even embed small toys or shapes inside the soap for fun gifts.
Step 4: Pour Into Molds
Pour the melted soap into silicone molds. Spray the surface lightly with rubbing alcohol to pop any surface bubbles and give your soap a glassy finish.
Step 5: Let It Set
Allow the soap to harden at room temperature for 1–2 hours. You can also place the molds in the fridge to speed up the process, but don’t freeze them.
Step 6: Unmold and Enjoy
Once solid, gently pop the soaps out of the molds. Wrap them in plastic wrap or store in an airtight container to prevent sweating (glycerin is a humectant and draws moisture from the air).
Tips for the Best Glycerin Soap
-
Use high-quality melt-and-pour base for better clarity and skin feel.
-
Avoid overheating, which can cloud the soap and reduce its clarity.
-
Wrap finished soap immediately to prevent moisture beads from forming on the surface.
-
Experiment with layering by letting one layer cool before pouring the next.
-
Try embeds like loofah slices, glitter, or confetti soap pieces for a fun look.
