Chemical properties |
It appears as colorless to light yellow transparent liquid with rum, fruit and cream aroma. The freezing point:-25 ° C; the boiling point: 154 ° C, specific rotation [a] 14d:-10 °. It is easily soluble in ethanol, acetone, ether, esters and other organic solvents; there is some degree of hydrolysis upon being miscible with water. Mouse oral LD50: 2.5g/kg, ADI is subject to no special provisions (FAO/WHO, 1994). |
Uses |
Ethyl lactate is the
food spices allowed in our country, commonly used in modulation of fruit
flavor, lactic acid-type food and wine flavor. The dosage is 1000mg/kg in
alcoholic beverage, 580-3100mg/kg in chewing gum, 71mg/kg in baked food,
28mg/kg in candy and 17mg/kg in cold drink according to normal production
requirement. |
Usage limit |

drink: 5.4; Cold drinks: 17; Candies 28; baked goods 71; pudding class 8.3;
gums 580 to 3100; alcohol 1000; syrup 35. |
Toxicity |
ADI is not subject
to specific special provisions (FAO/WHO, 1994). |
Content analysis |
About 0.7 g of the
sample was accurately weighed and then assayed as in Method I (OT-18). The
equivalent factor (e) in the calculation is 59.07. |
Chemical Properties |
Ethyl lactate has a light ethereal, buttery odor. |
Uses |
Ethyl lactate, for instance, is used in the electronics industry to remove salts and fat from circuit boards; it is also a component in paint strippers. |
Uses |
As solvent for nitrocellulose and cellulose acetate. |
Uses |
Ethyl Lactate is a solvent manufactured from l(+) lactic acid which is miscible in water and most organic solvents and is cleared for use as a flavoring agent. it is a naturally occurring constituent of california and spanish sherries. it is a clear, colorless, nontoxic liquid of low volatility, having a ph of 7–7.5. it is used as a food and beverage flavoring agent. |
Production Methods |
Ethyl lactate is produced by the esterification of lactic acid with ethanol in the presence of a little mineral oil, or by combination of acetaldehyde with hydrocyanic acid to form acetaldehyde cyanhydrin. This is followed by treatment with ethanol (95%) and hydrochloric or sulfuric acid. Purification is achieved using fractional distillation. The commercial product is a racemic mixture. |
Preparation |
d-Ethyl lactate is obtained from d-lactic acid by azeotropic distillation with ethyl alcohol or benzene in the presence of concentrated H2SO4; the l-form is prepared in a similar fashion starting from l-lactic acid; the racemic product is prepared by boiling for 24 hours optically inactive lactic acid with ethyl alcohol in carbon tetrachloride, or with an excess of ethyl alcohol in the presence of chlorosulfonic acid, or in the presence of benzenesulfonic acid in benzene solution. |
Aroma threshold values |
Detection: 50 to 250 ppm |
Taste threshold values |
Taste characteristics at 50 ppm: sweet, fruity, creamy, and pineapplelike with a caramellic brown nuance. |
General Description |
A clear colorless liquid with a mild odor. Flash point 115°F. Denser than water and soluble in water. Vapors heavier than air. |
Air & Water Reactions |
Flammable. Soluble in water. |
Reactivity Profile |
Ethyl lactate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. |
Hazard |
Moderate fire risk. |
Health Hazard |
Inhalation of concentrated vapor may cause drowsiness. Contact with liquid causes mild irritation of eyes and (on prolonged contact) skin. Ingestion may cause narcosis. |
Fire Hazard |
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. |
Chemical Reactivity |
Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent. |
Pharmaceutical Applications |
formulationsand recently as a co-solvent in emulsions and microemulsion technologies. It has also been used as a solvent for nitrocellulose, cellulose acetate, cellulose ethers, polyvinyl and other resins. It has been applied topically in the treatment of acne vulgaris,where it accumulates in the sebaceous glands and is hydrolyzed to ethanol and lactic acid, lowering the skin pH and exerting a bactericidal effect. |
storage |
Stable at normal temperature and pressure. Ethyl lactate is a flammable liquid and vapor. Store in a cool, dry, and well-ventilated location away from any fire hazard area, in a tightly closed container. |
Incompatibilities |
Incompatible with bases or strong alkalis and may cause fire or explosion with strong oxidizing agents. |
Regulatory Status |
GRAS listed. Reported in the EPA TSCA Inventory. |
