Spirodela Polyrrhiza Extract

Product Description

Green Stone Swiss supplies cosmetic-grade Spirodela Polyrrhiza Extract under a direct factory model, with GMP-aligned quality control, batch documentation, and sample support for botanical skincare formulators.

Spirodela Polyrrhiza Extract (INCI: Spirodela Polyrrhiza Extract; CAS 223748-79-6) is the extract of greater duckweed (Spirodela polyrhiza / polyrrhiza), an aquatic plant. CosIng lists skin-conditioning function. In leave-on systems it is valued for soothing, antioxidant-support, and lightweight hydration-oriented botanical concepts.

Confirm INCI spelling against your COA and target-market dictionaries—IECIC uses Polyrrhiza (double r), while some international listings use Polyrhiza.
