step-by-step overview of the bath bomb production process:
1. Prepare Dry Ingredients
Combine baking soda, citric acid, cornstarch, and other powders in a mixer until evenly blended.
2. Mix Wet Ingredients
In a separate container, blend oils, fragrances, colorants, and any emulsifiers.
3. Combine Wet and Dry Mixtures
Slowly add the wet mixture to the dry blend while mixing to prevent premature fizzing.
4. Adjust Texture
Check consistency—add a small amount of water or alcohol if needed until the mixture holds its shape when pressed.
5. Molding
Pack the mixture firmly into bath bomb molds, ensuring both halves are tightly compressed.
6. Demolding
Carefully remove the bath bombs from the molds after they hold shape.
7. Drying/Curing
Place the bath bombs in a dry, ventilated area for 24–48 hours to harden completely.
8. Packaging
Once fully dry, wrap or box them to protect from moisture and preserve fragrance.
