Polysorbate 80 liquid (a viscous, water-soluble yellow liquid) which is a food-grade product, normally used in the manufacture of ice cream. It is also an emulsifier that aids in dispersing oils in water rather than pooling on top. It also prevents mica and colours from sticking to or staining the bath.

Information you need to know when adding Polysorbate 80 to Bath Bombs
As it is a wetting ingredient, it means that you use less other wetting ingredients i.e. water, witch hazel, alcohol, to your bath bomb mixture. If you use it without making adjustments your mixture will be too wet.
The rule of thumb is 1 part Polysorbate 80 to 2 parts carrier oil (eg Sweet Almond oil, Coconut Oil). So if you use the recipe that we provide in our bath bomb kits, use 1 teaspoon of Polysorbate 80 to 2 teaspoons of Coconut Oil. Just remember to use the 1:2 ratio for any recipe you use.
Also, Polysorbate 80 should not be added straight to the dried mixture. It should be mixed with your other wet ingredients first; colours, oils, butters, fragrance oils, essential oils, etc.
