I do love DIYBathandbody's recipes...I've never tried her bath bombs. I started with this YouTube tutorial. she had really good tips. like adding citric acid very last.
DIY Mooncake Press Bath Bombs
That video lead me to this one that included recipe.
DIY Bath Bomb Free Recipe
I didn't have some ingredients at the time and had to adjust. But I didn't use mica (just different colors of clay) so didn't need polysorbate-80. and didn't have SLSa at the time. May try more again with the SLSa. I think it just adds more bubbles. But was always happy with the way they turned out. And everybody loved them.
This is my adjusted recipe:
INGREDIENTS:
Misc: BAKING SODA 56.60%
Salt: Epsom Salt 9.43%
Clays: Rose Clay 1.89%
BaseOil: Almond 0.94%
FO: Fragrance oil 1.42%
Misc: ALCOHOL 1.42%
Misc: CITRIC ACID 28.30%
NOTES: In a medium bowl, mix together all of the dry ingredients EXCEPT CITRIC ACID. MIX ON LOW SPEED FOR 3 MIN to combine.
In a separate small bowl, mix together the wet ingredients.
Add the wet ingredients to the dry ones very slowly.
WHEN WELL MIXED ADD CITRIC ACID.
Mix until combined, and the ingredients look like wet sand.
PACK AND PRESS IN MOLD. PLACE ON LINED SHEET PAN. Let the bath bombs dry for 24 hours before enjoying in the tub.
I used my kitchen aid mixer and just mixed each stage for 5 minutes or so. I mixed each stage alot... lol!
Have fun!
