About
A whole-plant extract from hiba cypress with thujone compounds and anti-inflammatory properties used in Japanese traditional skincare.
Thujopsis dolabrata (asunaro or hiba false cypress) water is a steam distillate from the whole plant, containing thujone, thujopsene, and related terpenoids characteristic of the cupressaceae family. The ingredient is used as a fragrance and skin conditioning agent in cosmetics. Thujone content in cupressaceae extracts is monitored under EU cosmetic regulations, though the steam-distilled water form represents a significantly diluted preparation compared to essential oils. No specific restrictions apply to this ingredient under Regulation 1223/2009, but IFRA allergen declaration requirements may apply depending on composition.
