What is Polysorbate 80?
What exactly is polysorbate 80? Polysorbate 80 can be a fairly important ingredient when making bath bombs. Polysorbate 80 comes in a liquid form (rather viscous), and is an amber to golden color. It is a synthetic emulsifier that helps dissolve substances. It is actually used in foods, medicine, and vaccines as well as cosmetics.
Why Polysorbate 80 in Bath Bombs?
Polysorbate 80 is used in many bath and beauty products for different reasons. However, in particular as it has to do with bath bombs, it helps for the oils and colors to disperse more evenly.
Have you ever used a bath bomb in which the color pooled at the top of the water or created a terrible ring around the tub?
Well, polysorbate 80 helps prevent this very annoyance.
In fact, colorants like mica’s that many DIYers or people selling bath bombs use, oftentimes leaves said colored ring around the tub. When polysorbate 80 is added to the bath bombs it helps distribute or disperse these colorants better in the water, preventing this issue.
Similarly, it will help disperse oils. Oils are not water soluble. Oils used in bath bombs can potentially be a safety concern. They tend to make the bottom of the tub slippery, after settling. However, oils can also have a wonderful effect on the skin, therefore makers include them in recipes. Polysorbate 80 helps to disperse the oils as well.
However, if you are one to use a considerable amount of heavy oils in bath bombs the bottom of the tub may be effected regardless.

Can I Avoid Polysorbate 80?
If you wish to eliminate polysorbate 80, you may want to think about the colorants and oils used. If you don’t want to have to deal with the ring from the colorant, you can use water soluble colorants. For example, bath certified dyes, (which typically have to be bloomed). Their are some water soluble “lake” colorants as well.
There are other liquid colorants you can find on the market that don’t need polysorbate 80, as they are water soluble. However, if you’re including any oils in your bath bombs, polysorbate 80 can be important.
Usage Rate: Typical usage rate in bath bombs is around 2-5%, & Lotion usage rate is 1-5%
Like most other things bath & beauty related, it’s important to test out percentages of polysorbate 80 dependent on the rates of other ingredients in your bath bombs, like colorants and oil usage.
