Butyl butyryllactate Usage And Synthesis

Chemical Properties

Butyl butyryl lactate has a taste similar to milk, mild cheese, butter and cream.

Uses

Butyl Butyryllactate is a synthetic flavoring agent that is a stable, colorless to light yellow liquid with the odor of cooked butter. it is miscible with alcohol and most fixed oils, soluble in propylene glycol, and insoluble in glycerin and water. it should be stored in glass, tin, or resin-lined containers. it is used in butter flavors with applica- tions in baked goods and candy at 14–60 ppm.

Definition

ChEBI: Butyl butyryllactate is a diester resulting from the formal condensation of the carboxy group of 2-(butanoyloxy)propanoic acid with butan-1-ol. It has a role as a flavouring agent and a plant metabolite. It is a diester and a butyrate ester. It is functionally related to a 2-hydroxypropanoic acid and a butan-1-ol.

Preparation

Butyl butyryllactate is prepared by acylation-esterification of Lactic acid.

Aroma threshold values

Aroma characteristics at around 1.0%: creamy, fatty, dairy-like, stale milky with waxy coconut-like nuances.

Taste threshold values

Taste characteristics at 5 ppm: creamy mouthfeel, buttery dairy, waxy, milky with coconut and cheesy nuances.

Flammability and Explosibility

Not classified

Biochem/physiol Actions

Taste at 5 ppm

Safety Profile

A skin irritant. See also ESTERS. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes.

Solubility in organics

Colorless to pale yellowish liquid.Soluble in propylene glycol, alcohol and oils.
