Phenoxyethyl isobutyrate

Description and usage notes:

Fruity, sweet, with green apple and powdery fruit blossom notes with aspects of honey and pastry. Versatile and easy to use.

This material is described with some enthusiasm by Arctander: “Sweet-fruity, rosy-floral, slightly honey-like odor of excellent tenacity … This ester has found quite extensive use in perfumery, and it is still surprising to see many perfume laboratories without that material on hand. … its odor type should place it among the most frequently used materials for daily use in fragrances for household products, soaps, detergents, room sprays, etc. where ‘volume’ is involved. It blends excellently with the Ionones and the ‘rose’ alcohols, with Terpineol and Linalool, Hydroxycitronellal and the Nitromusks, in Rose, Sweet Pea, Peony, Lilac, Honeysuckle, etc., and it is stable under normal conditions in various functional products.” 

Calkin & Jellinek recommend this material as a modifier for phenyl ethyl alcohol in rose, jasmine, lilac and violet compositions and with dimethyl benzyl carbinyl acetate in a variety of fruity accords, which they point out “produces an unmistakable character that survives even when used in trace amounts in a finished perfume” .
