How to make new soap from old soaps

Updated February 21, 2017

When you use glycerine soap until it is a small piece, it is common to simply toss the piece away and use a new bar of soap. Instead of throwing away the used soaps, you can make a new bar of soap out of the old pieces. It is important to make the new soap using used glycerine-based soap, which can be recycled successfully without separating or congealing. You can even add in your favourite fragrance oil to scent the new bar of soap as you prefer.

Cut old glycerine-based soap bars into 1/2-inch pieces using a paring knife. Catch the shavings into a large tin coffee can.

Place the can into a pot, and fill the pot with water.

Heat the pot until the soap melts completely.

Pour two tsp essential oil into the melted soap, and stir the mixture well with a wooden spoon.

Pour the melted, scented soap into soap moulds, and allow the soaps to cool completely before popping them out of the moulds.
