Sweet grass containing coumarin, a EU-regulated compound, used as a fragrance ingredient in natural cosmetics.

Hierochloe odorata (sweet grass or buffalo grass) is used in cosmetics primarily for its distinctive vanilla-like fragrance, attributed to coumarin and related coumarin derivatives. Coumarin is listed in EU Annex III of Regulation 1223/2009 with restrictions on maximum concentration in finished products due to its status as a regulated fragrance allergen and potential liver toxicity at high doses. The steam-distilled water form represents a significantly diluted preparation with lower coumarin content than essential oil forms.
