Description and usage notes:
Slightly more substantive and less sharp than ethyl methyl 2 butyrate, this material is an essential part of the fresh, juicy top-note in fruit accords and is particularly helpful in combination with the ethyl form.
Here is the description from the manufacturer, Givaudan: “Odor: Fruity, Pear, Pineapple, Green, Fresh, Diffusive. Use: Isopropyl Methyl-2-Butyrate is used for green-fruity accords like pear and apple. It provides significant freshness to perfumes in combination with floral elements.”
