Standardised extract of grapefruit seeds in plant glycerin (33:67).
The ingredient
In cosmetics, grapefruit seed extract (Citrus paradisi) is classed as a skin-conditioning agent. One supplier makes it by grinding grapefruit seeds and extracting them in a mix of water and glycerin; the mixture is then clarified and decontaminated by heat. The Cosmetic Ingredient Review Expert Panel concluded in 2016 that grapefruit seed extract is safe in the present practices of use and concentration in cosmetics when formulated to be non-irritating and non-sensitising.[2]

Hair and body care. Add 6 to 10 drops to a portion of shampoo or soap.
Precautions
Do not use the extract undiluted, and avoid contact with the eyes. Keep the bottle out of the reach of children.
