Description

Phenoxy Ethyl Isobutyrate, commonly known as PEIB or Phenirat, is a smooth and elegant floral-fruity aroma chemical valued for its soft, sweet and slightly balsamic character. It combines rosy, floral, fruity, honeyed and warm facets, making it useful for adding body and richness to fragrance compositions.

Its soft character works particularly well in floral accords where it can provide a rounded, smooth and slightly fruity effect. It can also help bridge delicate floral notes with warmer base materials.

In perfumery, PEIB is particularly useful in rose, floral, fruity-floral, honeyed, balsamic and oriental compositions. Its warm character also makes it suitable for creating soft and sophisticated fragrance bases.

Perfumers' Tip

PEIB is useful for adding a soft, fruity and rosy richness to floral compositions. Combine it with Phenethyl Alcohol, Geraniol and Citronellol for a fuller rose effect, or use it with Hedione and Jasmine materials for a more diffusive floral accord. Benzoin and Vanillin can emphasize its sweet warmth, while Sandalwood and white musks create a smooth, lasting base.
