Grapefruit Seed ExtractUpdated a month ago

(Additional Names: Citrus Grandis (Grapefruit) Seed Extract or GSE)

An antimicrobial preservative used in cosmetic products. Numerous tests by independent researchers have shown that its antimicrobial properties are due to synthetic preservatives contained in it, not the extract itself. The synthetic preservatives found in GSE include benzalkonium chloride, triclosan, or methylparaben, which are all on our Banished Ingredients list due to toxicity concerns.
