Citric Acid: A Versatile Ingredient from Bath to Kitchen
Citric acid is the quiet catalyst behind every bath fizzy. Derived from the natural acids found in citrus fruits and now commonly produced through the fermentation of plant sugars, it brings both history and function into the formulation. When it meets baking soda in water, it creates the gentle effervescence that defines a bath bomb, releasing minerals, oils, and botanicals into the bath.
