This effect of physically shielding unstable perfume components from contact with the water phase may perhaps be provided also by the stable components of the perfume compound itself, provided that the latter are present in sufficient excess. This would account for Paul Jellinek s observation (1954, p. 116) that "the presence of a soap-resistant aromatic delays the decomposition of compounds which are unstable to alkali, and may prevent it altogether," and for the common observation that unstable but powerful perfumery materials such as methyl heptine and octine carbonates which are normally used at very low levels exhibit better stability in practice than tests of their stability in pure form would have indicated.
