Grapefruit Seed Extract (GSE)

INCI: Glycerine, Citrus Grandis (Grapefruit) Seed Extract

CAS Number: 84696-38-8; 90045-43-5

General Description: A thick, amber liquid with a mildly citrus aroma. Grapefruit Seed Extract (45%) is mobilised in glycerine (60%). Naturally derived from grapefruit seeds and membrane. Also known as citracidal or pumelo seed extract.

Commonly used as an antioxidant in skincare, soap making and food applications to extend product life and prevent rancidity. GSE is non-toxic, natural, biodegradeable and considered environmentally safe.

There are many recipes and websites that will suggest using GSE as a natural preservative. Whilst it does have some antimicrobial and anti-fungal properties, it is not robust enough to use for this purpose and should always be combined with a preservative.

GSE is also sometimes confused with grapefruit essential oil – please be aware that these are two completely different products.
