How to Make Glycerin: 15 Steps
Introduction:
Glycerin, also known as glycerol, is a versatile and natural byproduct of soap making or biodiesel production. It can be used in skincare products, foods, pharmaceuticals and various other industries. In this article, we’ll walk you through 15 steps on how to make glycerin at home.
Step 1: Gather your supplies
Before you begin, collect the following materials: vegetable oil, water, a digital scale, a glass container, lye (sodium hydroxide), a stainless steel spoon, safety goggles and gloves.
Step 2: Measure the ingredients
Using a digital scale, weigh out 4 oz of vegetable oil and 6 oz of water.
Step 3: Prepare the lye solution
In a well-ventilated area, carefully mix one ounce of lye with six ounces of water in a glass container. Stir slowly with a stainless steel spoon until completely dissolved. This will create an exothermic reaction and release heat so be cautious and wear protective gear.
Step 4: Cool the lye solution
Let the lye solution cool down to room temperature before proceeding. This may take about an hour.
Step 5: Add oil to the solution
Slowly pour the vegetable oil into the cooled lye solution while stirring carefully with your spoon.
Step 6: Mix well
Continue mixing the solution for about 20-30 minutes to achieve proper saponification. The mixture should start to thicken as you mix.
Step 7: Monitor consistency
Once the mixture reaches a creamy consistency like that of pudding or custard, it’s ready to move on to the next step.
Step 8: Pour into mold
Pour your mixture into molds of chosen shapes and sizes. Let it rest undisturbed for about 24 hours.
Step 9: Wait for the soap to solidify
Allow your soap to harden in the molds for about five days.
Step 10: Remove from mold
After the soap has hardened, gently remove it from the molds.
Step 11: Cut soap into pieces
Cut your soap into smaller, more manageable pieces.
Step 12: Set up a boiling setup
Prepare a makeshift double boiler by placing a heat-resistant pot or container inside a larger pot filled halfway with water. Ensure that the smaller pot can fit into the larger pot without touching the bottom.
Step 13: Heat soap pieces
Place the soap pieces in the inner container of your double boiler setup and heat on low temperature. As you gently stir, soap should begin to dissolve and release glycerin.
Step 14: Collect glycerin
As glycerin is released, use a spoon or ladle to collect it from the surface of the melted soap. This can take some time and patience.
Step 15: Store glycerin
Store your homemade glycerin in an airtight container until ready to use.
Conclusion:
Now that you’ve learned how to make glycerin at home, you can easily incorporate this natural ingredient into various DIY projects such as skincare products, food recipes, or pharmaceuticals. Remember to always handle chemicals like lye with caution and take necessary safety precautions during this process. Happy DIY-ing!
