Isobutyl isobutyrate

Isobutyl isobutyrate (CAS 97-85-8), commonly abbreviated as IBIB, is an ester used in the flavor and fragrance industry for its clean, fruity, sweet character. Approved under FEMA 2189, it functions as a flavoring agent in food products and as a scent component in cosmetic formulations.

In food and beverage manufacturing, IBIB contributes fruity top notes to confectionery, baked goods, and fruit-flavored drinks, where low usage levels deliver high impact. Fragrance formulators incorporate it into personal care products such as lotions, shampoos, and soaps to impart light, fresh, sweet accords.

It also serves compounders building flavor concentrates and aroma blends, where its compatibility with other esters and terpenes supports complex profile construction. Industrial flavor houses sourcing for FEMA-compliant formulations rely on it as a cost-effective building block for tropical and stone-fruit flavor systems.

Isobutyl isobutyrate is supplied as a clear liquid in standard packaging ranging from drums to isotanks for bulk orders. It is available in food-grade quality meeting FEMA and flavor industry purity standards. Buyers should confirm specification sheets for purity thresholds and organoleptic benchmarks relevant to their application.
