Safety with Bath Bombs

We love doing bath bombs in our house as a fun activity during bath time. We do it sparingly though – as the ingredients in bath bombs can irritate skin if used too frequently. I would recommend to not use a bath bomb more than once a week with kids.

Since bath bombs contain baking soda and citric acid, we need to take some precaution when making them. I have included all of the safety tips you will find on any bath bomb making kit so please read and keep these in mind when making your own.

A couple of notes of safety: 

  • Adults only should make the bath bombs. Kids can help with measuring and stirring under adult supervision.
  • Keep away from eyes and mouth. Wash hands thoroughly after handling.
  • Do not use small toys with children under 3. This activity is recommended for ages 6+.
  • Do not put the bath bombs near your mouth or nose. We always wash hair and body first before placing the bath bomb in the water. Do not allow kids to put their head under the water once the bath bomb is in the bath. Do not allow kids to drink the bath water.
  • Rinse eyes immediately with water for several minutes if product comes in contact with them.
  • Do not use if you have any broken or irritated skin.
  • Do not put any small figurines in the drain of your tub. Take toys out before draining the tub.
  • Rinse the tub and body after use.
  • Bath bombs are not intended for cleansing the body. Avoid holding the bath bomb once it is placed in the water.
  • In case of adverse reaction, stop using and contact a physician.
  • Baking soda may cause an allergic reaction.
  • Do not use bath bombs every day. Use sparingly in a month and not more than once per week.

Supplies Needed to Make Bath Bombs

  • Small toys – like shopkins or dinosaurs (optional)

Salt Options for DIY Bath Bombs

Salt is not required to make a bath bomb. We have included fine sea salt as a replacement for Epsom salt you will see in a lot of recipes. If you would like to use Epsom salt instead, speak to your doctor before using for children.

Do not replace the fine sea salt with regular table salt. If you do not have fine sea salt, you can exclude this from the recipe.

Do the Bath Bombs Stain the Tub?

Only use a few drops of food coloring and you shouldn’t have a problem with staining in your tub. Because your bath is filled with water the food coloring becomes very diluted when dissolved in the tub. Do test a small amount first. And if any coloring remains after the bath, use a paper towel to wipe it off right away, then rinse with water. Use only 1 bath bomb per bath.

You can also use bath soap coloring dye which is water soluble and states it is stain free.

Storage Tips for Bath Bombs

Store inside a sealed plastic bag in a cool, dry place. If left out exposed to air, it will gradually lose some fizzing effect. Also avoid touching the bath bombs with wet hands.
