Ethyl L-lactate

CAS: 687-47-8

Overview

Ethyl L-lactate (CAS 687-47-8 ) is the L-enantiomer of ethyl lactate, a naturally derived ester produced from lactic acid and ethanol. It functions as a biodegradable solvent and flavoring agent across food, cosmetic, and polymer processing applications.

In food and beverage production, it contributes a mild, creamy, buttery note to flavor systems and is used as an acidulant in confectionery and dairy-style formulations. This versatile ingredient is recognized under FEMA 2440 for its safety and efficacy.

Cosmetic formulators incorporate it as a solvent and humectant carrier in skin-care products. Its ability to solubilize active ingredients supports stable emulsion and serum formulations while maintaining a favorable safety profile for topical use.

In the plastics and polymer industry, it serves as a processing solvent and stabilizer for biopolymers, including PLA-based systems. Its compatibility with bio-based materials supports green chemistry manufacturing targets and sustainable production cycles.

It also functions as a carrier solvent in coatings and cleaning formulations requiring low toxicity and high biodegradability profiles. This makes it an ideal replacement for traditional petroleum-based solvents in sensitive industrial environments.

Ethyl L-lactate is available as a clear liquid in food-grade and technical-grade specifications. Food-grade material is supplied to FCC standards, supporting direct use in flavor applications and ensuring compliance with global food safety regulations.

Bulk quantities are typically offered in drums and IBC containers, with high-purity grades available for cosmetic and specialty solvent applications. Our supply chain ensures consistent quality and availability for large-scale industrial manufacturing needs.
