About

Myrrh — the aromatic gum resin of Commiphora myrrha (CAS 9000-45-7). Long-used fragrance and astringent, but its essential-oil fraction can cause contact dermatitis.

Commiphora myrrha resin (myrrh, CAS 9000-45-7) is the oleo-gum-resin exuded from the Commiphora myrrha tree. It has been used in perfumery, oral care and traditional medicine for millennia. The essential-oil fraction contains furanosesquiterpenes (furanoeudesma-1,3-diene, curzerene), sesquiterpene hydrocarbons and trace aldehydes; several of these are documented contact allergens. Case reports describe Type IV dermatitis from myrrh-containing oral products and perfumes. Not EU-restricted as such, but the fragrance fraction must comply with SCCS allergen-declaration limits.
