Emulsifiers are natural or synthetic substances added to topical skin care products -- such as moisturizing or cleansing lotions -- to prevent the ingredients from separating. They work by binding together water and oils to create a stable mixture. Common emulsifiers you may recognize from the ingredients list for cosmetic preparations include lecithin, cetyl alcohol and polysorbate 20. You can make your own, all-natural emulsifier using beeswax and borax.
Things You'll Need
- Food grade mineral oil
- Fragrance oil (optional)
- 2 tall glass jars
- Large saucepan
- Circular metal cooking grid
- Glass mixing bowl
- Electric whisk
- Cooking thermometer
- Glass stirring rod
- Glass storage jar with secure, airtight lid
Place 26g beeswax and 55ml mineral oil in a tall glass jar.
Place 2g borax and 22ml of water in another tall glass jar.
Place a circular metal cooking grid at the bottom of a large saucepan.
Partly-fill the saucepan with water and place the glass jars containing the ingredients on top of the grid.
Gently heat the contents of the jars to melt the beeswax and dissolve the borax. Do not allow the ingredients to boil.
Remove from the heat, once the beeswax is fully melted and the borax completely dissolved.
Combine the contents of the jars in a glass mixing bowl. Blend them together using a electric whisk for approximately ten minutes, or until the mixture forms a white cream.
Continue to stir intermittently, until the mixture cools to 40 degrees Celsius. Use a cooking thermometer to monitor the temperature.
Add one drop of fragrance oil and stir in well, using a glass stirring rod. Skip this step for an unscented emulsion.
Transfer the emulsion to a glass jar for storage. Secure the lid.
