Bubble Bath / Bath Bomb Ingredients and Foaming
Question
Regarding a bubble bath formula containing baking soda (Sodium Bicarbonate), Citric Acid, Cream of Tartar, SLSA, Cocoa Butter, shea butter, Extract, Polysorbate 80, Liquid Glycerin, and Fragrance Oil: Are these ingredients sufficient? Which ingredient is responsible for creating foam? If I want more foam, which ingredient should I increase? Thank you.
Answer
Bubble Bath Formulation Ingredients
The ingredients you listed are commonly used in products like bath bombs or bubble bars, which create both fizz and bubbles in bathwater.
Here's how the ingredients contribute:
- SLSA (Sodium Lauryl Sulfoacetate) is the main ingredient that creates the abundant and stable foam (bubbles).
- Sodium Bicarbonate and Citric Acid react when wet to produce the fizzing effect.
- Other ingredients like butters, oils, and extracts provide skin conditioning, fragrance, and color.
How to Get More Foam
To achieve more bubbles, you should increase the proportion of SLSA in your formula. However, ensure the overall balance of your formulation is maintained, as ingredients like butters and oils can reduce foaming.
Based on the product information available:
- Sodium Bicarbonate is primarily used for adjusting pH to be more alkaline.
- Citric Acid (Anhydrous, Natural) is used for lowering pH.
Adjusting the amount of SLSA is key to increasing the bubble volume.
