What makes Phenylethyl Acetate distinctive

It is phenylethyl alcohol made fruity: the same honeyed rose, sweeter and with a peachy, berry-like fruitiness.

How Phenylethyl Acetate is used

Used in rose and fruity-floral compositions, and in fruit and honey flavours.

Typical role: blender (smooths the joins between other materials).

How Phenylethyl Acetate differs from similar materials

Phenylethyl Alcohol
The alcohol is milder and warmer; the acetate is sweeter and fruitier, with peach and berry.
Phenylethyl Isobutyrate
The isobutyrate is fruitier still, with pear, tea and wine nuances; the acetate is the simpler honeyed rose.
Phenylethyl Phenylacetate
Phenylethyl phenylacetate is heavier and lasts for days, a dried-rose honey base; the acetate is lighter, fruitier and more volatile.
Phenylethyl Propionate
Fraterworks finds the acetate a brighter, more volatile rose than phenylethyl propionate, which is warmer and fruity-honeyed. (compared directly by a cited source)
