About HAY WATER

An aromatic water from hay distillation used as a fragrance component, containing volatile compounds including coumarin with sensitisation concerns.

Detailed Analysis

Hay Water is an aqueous solution containing volatile oils obtained by the distillation of hay (various grass species). The composition includes coumarin, phytol, furan derivatives, and various aldehydes. Coumarin is listed in EU Annex III as a fragrance allergen requiring declaration when present above 0.001% in leave-on products. The IFRA standard restricts coumarin in fragrance compounds. Natural hay water composition varies with source grass species and growing conditions, creating variability in allergen content.
