Bubble bars give you the same relaxing feeling as a bubble bath, but provide thicker foam and a more intense smell than liquid bubble bath. Bubble bars comes in solid form and dissolve under running water. LUSH has a line of bubble bars that range in smell from spice to fruit and sweet fragrances. Make your own bubble bars just like the ones sold by LUSH at home, using your own molding trays and favorite essential oil flavors.

Measure and pour 1 cup of baking soda in a plastic bowl. If you want your bubble bar to be another color other than white, remove 1/4 cup of baking soda and pour into another bowl and mix it with a few drops of food coloring and stir. Once the baking soda and food coloring are mixed, combine it with the 3/4 cup of white baking soda.

Add 2 ml of an essential oil to the mixture and stir. Use a disposable dropper for measurements. You can use any scent you like, including sage or lavender.

Add 1 tbsp. of cream of tartar to the mixture and whisk until well-blended.

Whisk in 1 cup of sodium lauryl sulfoacetate to the mixture. This powdered material creates the foaming appearance in the bubble bar when mixed with water, and is made of coconut and palm oils. According to albabotanica.com, it removes oil, dirt and bacteria without drying out your skin.

Stir in a few drops of liquid glycerin.

Sprinkle a handful of baking soda in the the molding tray and pour in the liquid mixture. Let mixture sit for about 10 minutes to harden a bit.

Turn the molding tray over on to a piece of wax or parchment paper. Gently tap on the top of the molding tray until the bubble bar falls out. If it's crumbly, put it back into the molding tray and add a few more drops of liquid glycerin then dump on to wax or parchment paper again.

Store bubble bar in a sealed container.


Put on latex or protective gloves and a filtering mask prior mixing the ingredients. Sodium lauryl sulfoacetate is a fine powder and can be easily inhaled when the package is opened. Make mixture in a well-ventilated room.
