Sapona Guide to Making a Handmade Bath Bomb | Page 16

Why are homemade bath bombs soft?
If your homemade bath bomb is soft, chances are it contains too much moisture. To remedy
this issue, add more dry ingredients to balance out the moisture content. It can also be due
to living in a humid environment. Just add some cornstarch or clay to harden the bath
bombs.
How long do homemade bath bombs last?
Homemade bath bombs can last for as long as 6 months. However, the longer you wait to
use the bath bomb, the more exposed it will be to moisture in the air and the less likely it
will fizz when you drop it into the water. This is due to the citric acid used in most bath
bomb recipe as it tends to lose its potency if exposed to the air.
