Hazard Information

Chemical Properties

Buty stearate has no odor or a faintly fatty odor.

Chemical Properties

LOW MELTING SOLID OR LIQUID

Occurrence

Reported found in fresh apple and boiled mutton.

Definition

ChEBI: A fatty acid ester that is the butyl ester of stearic acid.

Preparation

By reacting silver state with n-butyl iodide at 100°C by transesterification of glyceryl tristearate (tristearin) with n-butyl alcohol.

General Description

Butyl stearate is a fatty acid ester, which has application in cosmetics, personal care products, and as an emollient in food industries.

Materials Uses

Butyl stearate as candle material: Besides the synthetic paraffins mentioned, other substances, individually or in combinations, may also have been added to the candle base material. These are in particular poly-alpha-olefins, low-melting point paraffin fractions and products which have been obtained from naturally occurring fats and oils and have been prepared by a chemical modification process, such as for example butyl stearate. Butyl stearate use in candle material

Purification Methods

Acidic impurities are removed by shaking with 0.05M NaOH or a 2% NaHCO3 solution, followed by several water washes, then purified by fractional freezing of the melt and fractional crystallisation from solvents with boiling points below 100o. [Beilstein 2 IV 1219.]
