The main ingredients of bath bombs and the functions of each component:

  • Baking soda - Acts as the base and produces carbon dioxide bubbles when reacting with citric acid.
  • Citric acid - Reacts with baking soda to produce fizzing. Also acts as a natural preservative.
  • Epsom salts - Adds therapeutic benefits and minerals. Epsom salt helps soothe sore muscles.
  • Fragrance oils - Add pleasant aromas. Popular scents include lavender, eucalyptus, rose, etc.

  • Carrier oils - Absorb into skin to moisturize. Sweet almond oil, coconut oil, olive oil are examples.
  • Botanicals - Dried flowers, herbs, oats or flower petals suspended in oils. Provide skin benefits.

  • Clays - Provide detoxifying effect. Bentonite and kaolin clays help cleanse and nourish skin.
  • Essential Oils - Pure plant extracts that provide aroma-therapeutic benefits. Lavender oil is calming, eucalyptus oil is invigorating.

How Does it Work?

The “bomb” aspect of a bath bomb is the fizziness. But what’s going on in those spheres that make them so fizzy? Two of the key ingredients to a bath bomb are citric acid and sodium bicarbonate. You might also know sodium bicarbonate by its more common name, baking soda. These two ingredients are what cause the impressive and delightful fizz when the bath bomb enters the water.
When sodium bicarbonate (NaHCO3) comes in contact with water, the sodium (Na) molecules break off from the bicarbonate (HCO3). At the same time, the citric acid is dissolving, with a single hydrogen ion (H+) separating from the rest of the molecule. When the released hydrogen ion from the citric acid encounters the bicarbonate from the baking soda another reaction happens! This time, carbon dioxide (CO2) gas is released as one of the end products. The carbon dioxide forms bubbles in the soap and bath water, and rushes to the surface with a delightful fizz.

What are the benefits of bath bombs

1. bask in fragrant heaven with carefully chosen bath bomb ingredients
Take a few minutes of mindfulness to gage your mood, and then choose your bath bomb ingredients and aromas accordingly. For example, choose bath bomb ingredients that have an aroma of invigorating mimosa flower for a stint in tropical paradise, or an aroma of heirloom French lavender for a relaxing spa session.
2. smooth out dryness for hydrated skin
Once dissolved in water, bath bombs release citric acid which fizzes up and helps loosen damaged layers of skin. The oils in bath bombs also tend to be super moisturizing, and basking in a tub of hydrating oils will leave your skin feeling soft and supple.
3. say goodbye to soreness and relax your body & your mind
With smoothing properties and delicious smells, bath bomb ingredients work to help you relax. Beyond just the bath bomb, lounging in a warm bath itself for between 15-20 minutes can help you decompress after a long day. For centuries, people have been using baths for their beneficial effects on our muscles, and recent studies confirm that a warm bath can help soothe soreness and tension.
4. detox your skin and leave your bath feeling refreshed and renewed
