Naturally Colored Rose Clay Bath Bombs

Updated: Oct 19

Ingredients

In a large bowl, combine baking soda, citric acid, SLSA, cream of tartar, rose clay and kaolin clay. Mix thoroughly and be sure to break down any clumps. I find it easiest to sift the ingredients (do not sift SLSA). When using SLSA be sure to wear a respirator mask.
In a small cup or beaker, mix the grapeseed oil, fragrance oil, and polysorbate 80 then slowly pour it into the large bowl containing the dry mixture.
In a separate container, weigh out the witch hazel then slowly pour it into the large bowl containing the other ingredients. I find it best to mix with a whisk while pouring. The mixture will begin to slowly bubble/activate but mixing while pouring will minimize this. If spraying witch hazel instead of weighing, lightly spritz witch hazel into the mixture while stirring, just until it holds together when squeezed in your hand. Be sure to not overdo it.
Mix by hand until your mixture can be firmly squeezed and hold together.
Fill up the mold with the mixture then press. If your bath bomb mixture starts to dry out or your bath bombs break apart, spritz mixture with a very small amount of witch hazel and mix.
Allow the bath bombs to dry (a dehumidifier helps if your space is humid).

Grapeseed oil can be substituted for sunflower oil, sweet almond oil, safflower oil, or your favorite liquid carrier oil.
Swap kaolin clay for more rose clay if you want a richer pink.
Bath bombs are best packaged in shrink wrap or stored in an airtight container.
This recipe makes about 8 bath bombs (depending on mold size).
