Composition

Bath bombs’ primary ingredients are a weak acid and a bicarbonate base. These are unreactive when dry, but react vigorously when dissolved in water to produce their characteristic fizzing over a period of several minutes. This is an acid-base reaction that involves conversion of citric acid and sodium bicarbonate to sodium citrate and carbon dioxide:

C5H7O5CO2H (aq.) + NaHCO3 (aq.) → C5H7O5CO2−Na+(aq.) + H2O(l) + CO2 (g)

HOCO2−Na+(aq.) + H2O (l) → HOCO2H (aq.) + NaOH (aq.)

RCO2CH2CH(O2CR′)CH2CO2R″(l) + 3 NaOH (aq.) → HOCH2CH(OH)CH2OH (l) + RCO2Na (aq.) (+ R’CO2Na + R”CO2Na)

The other ingredients in bath bombs can vary considerably. However, most have scented ingredients as well as dye to impart a pleasant fragrance and color to bathwater. Lathering agents, such as sodium lauryl sulfate, are also often added to create bubble foams.
