Phenylethyl Formate
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
The Full Story
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.

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.
