What it is
Chamaecyparis Obtusa Water is the water phase obtained when steam-distilling the wood or leaves of hinoki, the Japanese cypress. It carries trace aromatic and water-soluble constituents from the tree and contributes a characteristic woody scent along with a light conditioning effect. In sunscreens it often appears as part of the water base in products with a botanical or spa-inspired positioning.
Safety & warnings
Generally well tolerated as a botanical water. Because it carries naturally aromatic constituents, individuals sensitive to plant-derived scents could occasionally react, though it is used at modest levels.
Origin & sourcing
Natural; the aqueous fraction recovered from distillation of Chamaecyparis obtusa, a conifer cultivated in Japan and East Asia.
History
Hinoki has a long cultural role in Japan for construction, bathing, and aromatics, and hinoki water draws on that heritage in cosmetic use.
