Food grade 99% Ethyl oleate CAS 111-62-6

Product Overview

Ethyl oleate (CAS 111-62-6) is the ethyl ester of oleic acid — a colorless to light-yellow, low-viscosity oily liquid with a mild floral odor, chemically CH₃(CH₂)₇CH=CH(CH₂)₇COOC₂H₅. It is one of the most widely used oleochemical esters: a flavoring ingredient with an established safety record, a solvent and co-solvent in agrochemical formulations, a lubricant and plasticizer, and a renewable platform molecule for green-chemistry transformations such as the production of oleyl alcohol and 1-decene. Its combination of fluidity, low melting point (−32 °C), hydrophobic character and biodegradability makes it a practical, renewable choice across food, agricultural, industrial and specialty-chemical applications

Core value propositions:

● Food-Grade Flavor Ester: recognized safe as a flavoring agent with worldwide acceptance;

● Renewable Oleochemical: plant-derived fatty acid ester, biodegradable and low-odor;

● Versatile Solvent & Carrier: fluid, hydrophobic and compatible with oils and agrochemical systems;

● Green-Chemistry Platform: clean feedstock for oleyl alcohol, 1-decene and other derivatives.

Product Information (Quick Facts)

Chemistry & Structure

Ethyl oleate is the ethyl ester of oleic acid: a C18 monounsaturated fatty chain in the cis configuration — double bond at the 9,10-position (Z) — carrying an ethoxy ester head group, giving the structure CH₃(CH₂)₇CH=CH(CH₂)₇COOC₂H₅. The single cis double bond bends the alkyl chain, which keeps the ester fluid and low-melting (melting point −32 °C) and prevents crystallization even at low temperature. The ester head group gives the molecule classic fatty-ester solubility behavior: it is insoluble in water, freely soluble in ethanol, diethyl ether and most organic solvents, non-corrosive, and chemically stable under normal storage. As a monounsaturated fatty ester it is compatible with oils, waxes and hydrocarbon systems, biodegradable, and its cis-alkene provides a reactive handle for transformations such as hydrogenation and olefin metathesis. The product is a colorless to light-yellow liquid with a low flash point risk profile (flash point above 113 °C) and no GHS hazard classification.

Main Applications

1 Flavoring & Food Applications (Core Application)

Ethyl oleate is an approved flavouring substance with a long history of use

● Favouring agent: gives a mild, fruity-fatty note to flavour formulations.

● Food additive use: Not considered to be a safety concern at current levels of intake.

● Solvent/carrier for flavour oils – solubilises lipophilic aroma components in finished flavours.

● Food-contact compatibility: fatty ester with a clean toxicological profile for food-adjacent uses.

2 Agrochemical & Feed Applications

Ethyl oleate is a safe and effective solvent and carrier in agricultural chemistry:

● Pesticide solvent / co-solvent - dissolves the active ingredients in emulsifiable and oil-based formulations.

● Non-food pesticide product inert ingredient; permitted carrier in certain agrochemical systems.

● Feed flavourings: improves the palatability of feed rations.

● Agricultural chemical manufacturing: Oleochemical solvent of choice for standard formulation lines.

3 Lubricants & Industrial Fluids

As a fatty acid ester, ethyl oleate is a natural lubricity and film-forming component:

● Lubricant base/additive: low friction, good film strength in light-duty and specialty lubricants.

● Metalworking fluids: boundary lubricity and anti-wear contribution in oil-based formulations.

● Compatible with oils and greases: blends into petroleum and bio-based lubricant systems.

4 Plasticizers & Polymer Applications

Ethyl oleate functions as a low-migration, bio-based plasticizing ester:

● Plasticizer: softens and flexibilizes polymer formulations, particularly PVC and related resins.

● Processing aid: improves flow and surface finish in compounded plastics.

● Renewable alternative: plant-derived plasticizing ester for sustainability-focused formulations.

5 Fine Chemical & Green-Chemistry Building Block

The cis-olefin and ester functionality make ethyl oleate a classic platform molecule:

● Bouveault–Blanc reduction: classic route to oleyl alcohol and ethanol from the ester.

● Ethenolysis (olefin metathesis): conversion to 1-decene and 9-decenoate esters for polymer and fine-chemical feedstocks.

● Hydrogenation and derivatization: gateway to saturated esters, fatty alcohols and oleochemicals.

● Naturally occurring signal molecule: identified as a honeybee primer pheromone, confirming its benign natural role.

FAQ

Q1: What is ethyl oleate used for?

Ethyl oleate is a versatile oleochemical ester. Its main uses are as a flavoring ingredient, as a solvent/co-solvent and inert carrier in agrochemical formulations, as a feed flavoring, as a lubricant and plasticizer in industrial formulations, and as a renewable platform molecule for fine chemicals such as oleyl alcohol and 1-decene.

Q2: Is ethyl oleate safe?

Ethyl oleate has a clean safety profile. It is evaluated as safe when used as a flavoring agent at current levels of intake, and it is not classified as hazardous under GHS criteria. Prolonged skin or eye contact may cause mild irritation, so standard gloves and eye protection are recommended in handling.

Q3: How is ethyl oleate different from oleic acid?

Ethyl oleate is the ethyl ester of oleic acid. In the ester, the acidic carboxyl proton of the free acid is replaced by an ethyl group, which removes the acidity, lowers the melting point (−32 °C vs. about 13–16 °C for oleic acid) and increases compatibility with oils and organic solvents. The ester form is also more stable and has a milder odor, which is why it is preferred in flavors, agrochemical solvents and cosmetic-type oil phases.

Q4: Why is ethyl oleate a green-chemistry building block?

Ethyl oleate is plant-derived, biodegradable and carries a reactive cis double bond. In the classic Bouveault–Blanc reduction it is converted to oleyl alcohol, and by olefin metathesis (ethenolysis) it can be transformed into 1-decene and 9-decenoate esters — valuable comonomers and fine-chemical feedstocks. These routes turn a renewable fatty ester into high-value oleochemical products.
