-Fig leaf absolute is a dark green solid paste with herbal green odor used formerly in perfumery. "Do not use on any part of the body because of extreme phototoxic effects. The leaves are extracted with petroleum ether and the resulting concrete is washed with alcohol to produce the absolute."  +**Fig leaf absolute**

 +The leaves of Ficus carica are extracted with solvent to obtain a concrete, which is subsequent treated with alcohol. The residue represents a dark green to brownish green viscous liquid of a sweet, green, herbaceous, somewhat woody odor with a mossy undertone. The first distillation range (30-160°C/0.05 Torr) of this fig leaf absolute is the olfactory relevant part - only 1% (!). Main components of this part are hydrocarbons like caryophyllene, α- and β-farnesene, furthermore linalool, benzyl acetate, (Z)-3-hexenyl tiglate, methyl salicylate, β-ionone, and (Z)-3-hexenyl benzoate. Minor components are (Z)-3-hexenyl butyrate, (Z)-3-hexenyl 2-methylbutyrate, methyl benzoate, linalyl acetate, β-cyclocitral, safranal, α-terpineol, benzyl alcohol, geranyl acetate, phenylethanol, β-damascenone, geranylacetone, jasmone, caryophyllene oxide, and cinnamyl acetate e.g. Further minor but olfactory important constituents were pyridines and pyrazines like 2-isobutyl 4-methylpyridine (tobacco-like, green), 2-isobutanoyl 4-methylpyridine, 2-isobutenyl 4-methylpyridine (tobacco-like, bitter, fruity-floral), 2-methoxy 3-isopropylpyrazine, 2-methoxy 3-sec.butylylpyrazine, 2-methoxy 3-isobutylpyrazine e.g. \\

 "Based on sensitization reactions at 5% and strong phototoxic reactions, the Panel concluded that the material should be banned. A RIFM Advisory Letter (RIFM, 1980) was issued to all members stating the potential for induction of skin and phototoxic reactions. As a result, an IFRA Guideline (now renamed a Standard) was issued in October, 1980 (IFRA, 1980), which stated, ‘‘Fig Leaf Absolute should not be used as a fragrance ingredient based on test results of RIFM showing sensitizing and extreme phototoxic potential for this material.’’ A RIFM "Based on sensitization reactions at 5% and strong phototoxic reactions, the Panel concluded that the material should be banned.
