Definition

Light, rosy-green with a fresh, slightly unripe quality. Phenylethyl formate smells like rose petals caught by a gust of cold morning air — floral, crisp, fleeting.

Scent

Light, fresh, green-rosy. Brighter and less sweet than phenylethyl alcohol. A crisp, slightly unripe quality — rose buds rather than open flowers. More volatile, less rounded, more transparent. Quick evaporation; on blotter, it fades within an hour to a faint, clean floral trace.

The Full Story

CAS 104-62-1. The formate ester of phenylethyl alcohol. The ester modification adds a lighter, greener, more volatile character to the warm rosy base of PEA. The result is a fresh, slightly green-rose note that functions as a top-note lifter.

The scent is floral-rosy but brighter and more transparent than phenylethyl alcohol itself. The formate group gives it a slightly green, unripe quality — like rose petals before they fully open. It is more ephemeral, less sweet, and less rounded than PEA. The molecule evaporates relatively quickly, making it a top-note contributor.

In perfumery, phenylethyl formate is used to add fresh, green-rose lift to floral compositions. It provides the opening freshness that the heavier PEA cannot deliver.

Did You Know?

The formate ester series demonstrates a perfumery principle: shorter acid chains produce lighter, more volatile esters. Phenylethyl formate (C1 acid) is the lightest and most volatile rose ester; phenylethyl acetate (C2) is slightly heavier; phenylethyl propionate (C3) is heavier still. Each step up the acid chain trades freshness for body.

Extraction & Chemistry

In Perfumery

Top-note lifter in rose and fresh-floral compositions. Phenylethyl formate provides the opening rose freshness that PEA is too heavy to deliver. It works in fresh-rose accords, green-floral compositions, and as a modifier that brightens heavier floral hearts. The molecule's quick evaporation means it contributes to first impressions, not longevity.
