Butyl stearate Usage And Synthesis

Chemical Properties

Butyl stearate is a colorless or pale yellow oily liquid or low melting waxy solid. It has no odor or a faintly fatty odor. soluble in acetone, chloroform, soluble in ethanol, insoluble in water.

Occurrence

Reported found in fresh apple and boiled mutton.

Uses

Butyl stearate is used as finishing agents, lubricants and lubricant additives. It is also used as a plasticizer, food packaging material and as a dye solvent. It acts as a reactant and involved in the preparation of octadecanoic acid methyl ester by reacting with methanol. It finds application as a binder in cosmetics like soaps, shampoos and shaving creams, skin conditioners and surfactants for cosmetic formulations. butyl stearate is a stearic acid used in very small quantities in cosmetic preparations as an emulsifier for creams and lotions. It has been shown to cause allergic reactions.

Preparation

Butyl stearate is obtained by esterification of stearic acid and butanol, dealcoholization, washing with water and pressure filtration.
By reacting silver state with n-butyl iodide at 100°C by transesterification of glyceryl tristearate (tristearin) with n-butyl alcohol.

Definition

ChEBI: Butyl octadecanoate is a fatty acid ester that is the butyl ester of stearic acid. It has a role as an algal metabolite. It derives from an octadecanoic acid.

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.

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.]
