About

Rhubarb root water with natural astringent and skin-toning properties.

Rheum palmatum root contains anthraquinone derivatives (emodin, aloe-emodin, rhein) and tannins. Anthraquinones are subject to scrutiny under EU Regulation 1223/2009; aloe-emodin is listed in Annex III for certain applications. The steam-distillate form used in root water significantly reduces anthraquinone content compared to extracts, improving the safety margin for cosmetic use.
