Beetroot is a very well known colourant for water-based natural cosmetics. Its main chemical compound is called betanin, which degrades when subjected to light, heat, and oxygen. Infuse beetroot powder into glycerin to create a bright pink or red glycerite which you can use in your emulsions or water-based gels and tonics. Remember that beetroot is water-soluble so will not work in oil macerations.
