Phenyl Ethyl Isobutyrate (CAS# 103-48-0) is a fruity, sweet ester with a soft and refined character. Its scent recalls a blend of ripe berries and red fruits with peach–apricot facets, wrapped in a honeyed rose nuance and a light, wine-like accent. The overall impression is juicy and mouthwatering yet warm and comforting, offering a “sweet but not cloying” fruity note that feels more elegant than many standard fruity esters.

In fragrance compositions, Phenyl Ethyl Isobutyrate is often used to build or reinforce fruity–floral themes such as strawberry, red fruits, peach, apricot, grape, tropical fruits, candy and honey accords. It creates a smooth bridge between floral notes (especially rose, peony and soft white florals) and the fruity top and heart, adding roundness and a gourmand, inviting quality to the accord. This material also performs very well in personal care and home care fragrances such as shower gels, shampoos and room sprays, where its clean, friendly fruitiness suits mainstream consumer preferences.

From a technical standpoint, Phenyl Ethyl Isobutyrate is an ester of phenethyl alcohol with good substantivity in the middle to drydown of a formula, helping to prolong fruity and honeyed effects on skin and substrates. Even at low dosages it can smooth out sharp edges, enrich the body of the fragrance and lend a more natural character to other fruity synthetics. It is a versatile tool for perfumers looking for a refined fruity–rose nuance that is easy to use across many commercial fragrance styles.
