Description
STANDARDISED BOTANICAL ACTIVE
Glycyrrhiza glabra Root — 40%-90% Glabridin
Glabridin is the oil-soluble isoflavonoid in licorice root that cosmetic formulators buy for skin-brightening work. It is separated from the water-soluble glycyrrhizin fraction, so a glabridin grade and a glycyrrhizin grade are different products from the same root.

Buyer Decision Guide
Name the grade when you enquire: 40% and 90% carry different price bases and the 90% is not a simple concentration of the 40%.
- Assay: glabridin by HPLC, grade fixed in the written quotation within the 40%-90% range.
- Separation: glabridin is the oil-soluble fraction; glycyrrhizin is a separate product from this root.
- Colour: white to light yellow. A strong yellow cast suggests carry-over of other flavonoids.
- Solubility: oil-soluble. State your carrier system before ordering bulk.
- Residual solvents: declared per lot against the limits of the destination market.
- Documentation: COA, specification sheet and SDS with each batch.
How This Grade Differs
The site lists a licorice 10:1 extract and dipotassium glycyrrhizate. Neither is a glabridin grade: the 10:1 keeps the whole root profile and the glycyrrhizate is the water-soluble salt.
Quality and Documentation
Released on a batch certificate covering assay, related flavonoids, residual solvents, heavy metals and microbiology.
