PEG 200 In Bath Bombs
Hello,
This is my formula for bath bombs.
16 cups Sodium Bicarbonate
8 cups Citric Acid
4 Cups Powdered Sugar
1/2 Cup Fragrance Oils
1/4 Cup PEG 200I added PEG 200 because it eliminates the chance of the bath bombs not hardening correctly. They come out perfect every time. However, I want to phase that ingredient out. I need to understand how PEG 200 works as a hardening agent so I can potentially replace it with something more natural.
Thank you,

The first thing you should do is to figure out the relative percentages of your ingredients. Volumetric measurements are less helpful for formulating. That might be fine for home chefs but for cosmetic formulating & even industrial manufacture of food, ingredients are listed in terms of percentages.
The easiest way to do this is to weigh the mass of each of your compounds.
e.g. = 16 cups of Sodium Bicarbonate ~ 3700 g
4 cups powdered sugar = 460 g
8 cups citric acid = 2300 gOnce everything is in the same unit of measurement, you have a formula in which you can experiment and people can give you useful answers.
But PEG 200 is derived from natural ingredients so I don’t know how much more natural you’ll be able to get. In this formula it is a binding agent with adhesive properties. Maybe something like Ethylcellulose or Methylcellulose might work.
