<p>Epoxynitriles used as odoriferous substances in new perfume compsns. have formula R1R2 CH-CN (I) (where R1 is 4-10C alkyl; R2 is 1-5 alkyl; or R1 and R2 together with oxirane ring C-atom can form an opt. alkyl-substd. 5-11C carbocyclic ring system). In pref. (I), R2 is Me and R1 and R2 together with oxirane ring-C are closed to an opt. alkyl-substd. alicyclic 6-11C ring. Perfume compsns. pref. contain 1-50 wt. % (I). Compsns. may be used (i) directly as perfumes, (ii) for perfuming cosmetics, e.g. greams, lotions, soaps, (iii) for improving odour of technical prods., e.g. detergents, disinfectans and textile finishing agents. (I) impart interesting fragrance notes, cling well and are capable of combining to new scents. In an example, a tobacco-based perfume compsn. contained 20 wt. % 2,3-epoxy-3,3-hexamethylene propionitrile.</p> |
