First of all, it’s important to understand the difference between vegetable glycerin and glycerin soap. Vegetable glycerin is a colourless, viscous liquid that is used to make cosmetics; glycerin soap (also known as “melt and pour”) is a solid soap, either transparent or opaque white, that can be melted.
Our glycerin soap bases are of plant origin, respect the pH of your skin, and are environmentally friendly since they contain no petroleum by-products.
Their melting point is about 55°C (131°F), so be careful not to burn yourself when melting.
Unlike with cold process soaps, glycerin soap is usable as soon as it cools, so you can make it and give it away the same day.
And it’s a great activity for kids (with adult supervision of course).
- A heat-resistant measuring cup
- A metal spoon
- Heat-resistant molds (soap molds, ice cube tray, etc.)
- Microwave oven or pots for a double boiler
- A sharp knife
- Pipettes for the essential oils
- A scale
- Glycerin soap of your choice (white or transparent)
- Aromatic essences or essential oils (your choice)
- Optional: colorants for glycerin soap, dried flowers, exfoliating grains, etc.
Steps to follow
1. Choose your mold.
To figure out how much soap base to cut, just weigh the empty mold, then fill it with water. The weight of the water gives you the weight of the glycerin soap to cut. Using a sharp knife, cut off pieces of your basic soap.
2. Put the pieces in the measuring cup and melt them in the double boiler or microwave oven. Click here to learn how to make a double boiler.
Warning : if you are using a microwave oven, heat the soap just a few seconds at a time (no more than ten seconds); otherwise you could create a “soap volcano” in your microwave.
3. Once your soap has melted, remove it from the double boiler, stir, and immediately add colorant. If the mixture becomes too thick or solid, melt it again (but not for too long).
4. Now it’s time to add the essential oils or aromatic essences according to the concentrations indicated on the bottles – generally 3 to 5%. If desired, add the dried flowers and exfoliating grains, etc.
5. Pour the soap into the mold. To stop bubbles from forming on the surface of the soap as it cools, you can spray it with a little rubbing alcohol.
6. Let cool (approximately 45 minutes) and unmold.
