What is a Bath Bomb?

Bath bombs, also known as bath fizzers, are dry ingredients that are designed to effervesce once in contact with warm water. Once it hits the water, it releases essential oils, scents, colors, and bubbles to elevate your bath experience. Bath bombs can help condition the skin and soothe sore muscles. Additionally, they may help detox and relax the body and mind.   The great thing about bath bombs is that they contain the precise amount of oils and bath salts that you would normally have to purchase separately. Not only does using bath fizzers speed up the bath time process, but they make the experience so much better.  


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)

There is also a side saponification reaction that produces soap.  This involves a reaction between sodium bicarbonate and water, which gives carbonic acid and sodium hydroxide.  Sodium hydroxide, in presence of essential oils, undergoes a reaction to give glycerol and fatty acid salts as follows:
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.

Shape and effect

Bath bombs are normally ball-shaped, but can be found in a variety of shapes and effect.  Shapes could be ball shape,heart shape, cake shape, leaf shape, diamond shape etc.  Effect could be single color, mixed color, bath bombs with salt insides, bath bombs with dried flower inside or some toys inside, etc.
