There are a few reasons why there is a mold problem, and here we include them for you to understand the core reason.

Expiry date:

the main reason for mold growth would be the expiration date. The expiration date will degrade the integrity of the bath bombs, and thus they will change. Because the manufacturing ingredients in the bath bombs have expired, they have an expiration date. There are several products on the bath bomb that will affect the overall process. Here we include the expiration dates of some of the products and their expiration dates:

  1. Baking soda: 18 months
  2. Citric acid: 3 years
  3. Olive oil: 2 years
  4. Coconut oil: 1 year
  5. Castor Oil: 1 year
  6. Canola oil: 1 year
  7. Apricot-Kernel Oil: 1 year
  8. Avocado oil: 1 year
  9. Essential oil: 2 years
  10. Shea Butter: 2 years
  11. Oatmeal: 1 year

And the products that we included are some of the most common products used in bath bombs. And thus, as soon as they tend to expire, the bath bombs expire as well. Even though citric acid has a 3-year expiry date, it will only last this long if kept in an airtight container.

Direct sun:

again, another fact that would be related to the bath bomb molds is when they are exposed directly to the sun for a long time. In that way, the chances of mold growth are high. This might be the cause because the direct sun heat will lead to baking soda and citric acid reaction.


Another reason for mold growth is moisture. And for most of the bath bombs that are kept in the dark, humid place like a bathroom, the chances of mold growth are high. When there’s water and food to feed the mold, it will grow.
