Moderately toxic via
intraperitoneal route. Mildly toxic by
ingestion. Moderately irritating to eyes, sh,
and mucous membranes by inhalation.
Narcotic in hgh concentrations. Flammable
liquid. To fight fire, use alcohol foam, foam,
CO2, dry chemical. Incompatible with
oxidizing materials. When heated to
decomposition it emits acrid and irritating

| Hazard Information | Back Directory | [General Description]
A colorless liquid. Insoluble in water. A marine pollutant. Poses a threat to the aquatic environment. Immediate steps should be taken to prevent spread to the environment. May penetrate soils and contaminate groundwater and nearby waterways. Mildly irritates the eyes and skin. | [Reactivity Profile]
BUTYL BUTYRATE(109-21-7) reacts with acids to liberate heat along with butyl alcohol and butyric acid. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by interaction with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides. May attack some forms of plastics [USCG, 1999]. | [Air & Water Reactions]
Insoluble in water. | [Hazard]
Irritant and narcotic. Moderate fire risk.
| [Health Hazard]
Inhalation or ingestion causes headache, dizziness, nausea, vomiting, and narcosis. Contact with liquid irritates eyes. | [Fire Hazard]
Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot. | [Chemical Properties]

| Questions And Answer | Back Directory | [Description]
Butyl butyrate is a kind of ester formed through the condensation of butyric acid and n-butanol. It has a pleasant flavor, and thus being used in the flavor industry to generate a sweet fruity flavor of pineapple-like. It occurs naturally in many kinds of fruits including apple, banana, berries, pear, plum, and strawberry. It is also found in alcoholic beverages. However, it should be noted that it is a marine pollutant, posing a threat to the marine environment. It may also penetrate into soil, contaminating groundwater and other nearby waterways.
| [Aroma]
Fresh and sweet-fruity, powerful and rather
diffusive odor, reminiscent of Banana (overripe) and Pineapple.
Sweet and rich, fruity taste, pleasant in
proper dilution.
Occasionally used in perfume compositions,
mainly for special fruity notes in lipstick perfumes, or for modifying notes in novelty
fragrances, where formerly Allyl caproate has
been used in certain fragrance types.
Extensively used in flavor compositions for
imitation Apple, Banana, Berry, Butler,
Liquor, Peach, Pear, Pineapple, Nut, Scotch
(whisky), Quince, etc. | [References]
