How to make a bubble bar

Before you begin

  • Sodium cocoyl isethionate (SCI) can irritate your respiratory tract, so handle it with caution: work in a well-ventilated space or wear a dust mask.
  • In this bubble bar recipe, we use coco glucoside (pH 12). It is very important to wear gloves and safety glasses when handling this ingredient. Rest assured, the pH of the final product is skin-compatible.

Good to know!

  • We chose to use arrowroot starch for its lovely softening properties, but you can use a different starch if you prefer. 
  • SCI, coco glucoside, and coco betaine are gentle cleansing agents. They are suitable for people with all skin types, even sensitive skin.
  • Careful: some essential oils are dermocaustic (for example: cinnamon, clove, peppermint, and thyme, among others). They should not make up more than 0.5% of your bubble bar recipe, as they can irritate, or even burn, your skin.
  • You can also use mica or oxides to colour your homemade bubble bars. These powder colourants can constitute up to 3% of your total recipe, but keep in mind they will end up floating on the surface of the bathwater. 

Steps to follow

  1. Prepare and disinfect your equipment and workspace.
  2. Weigh the SCI and carefully grind it in a coffee grinder or with a mortar and pestle. Be sure to wear a dust mask or to work under the hood of your stove, with the fan on.
  3. Weigh the other dry ingredients (arrowroot starch and cream of tartar) and add them to the first bowl, along with the SCI.homemade bubble bar
  4. Weigh the liquid ingredients (coco glucoside, coco betaine, and scents) in a second bowl. 
  5. Add the liquid ingredients to the bowl containing the dry ingredients. Mix well with the spatula, then mix with your hands until the batter is compact and homogeneous.DIY bubble bar

Use and conservation

This recipe is formulated for all skin types.

To use your DIY bubble bar, place the whole bar or just a piece of it under the stream of water as you fill your bath. The stronger the stream, the more bubbles you’ll get.

Store unused pieces in a dry place. When made in optimal sanitary conditions, they will keep for at least six months.
