Opaque soap is easier to color for decorative purposes.

Glycerin soap base is often sold in clear blocks, even if it's a honey-glycerin base which is clear-yellow in appearance. When you want a solid, opaque bar of soap you can use glycerin soap and customize it to fit your needs. Knowing how to make glycerin soap opaque isn't difficult, and only requires a few extra ingredients. This gives you the opportunity to create attractive body cleansing products.

Things You'll Need

• 1 cup glycerin melt and pour (MP) base
• 2 qt. glass bowl
• Stirring wand
• 1 tsp. titanium dioxide
• 1 tsp. optional colorant

Instructions

1. Put the glycerin melt and pour base in the glass bowl. Microwave the bowl on high for three minutes, or until the base is melted into a liquid state.

2. Stir in the titanium dioxide. Titanium dioxide is a natural mineral pigment that turns beauty formulations creamy, opaque-white in appearance. Stir thoroughly.

3. Add the optional colorant. You can either use a food coloring of your choice or a mica mineral pigment. Mineral mica can be purchased from craft and hobby supply stores with the rest of your soap making materials.

4. Pour the melted soap into an 8 oz. soap mold or two 4 oz. soap molds. Place the mold in the freezer for 45 minutes.
