Ethyl lactate is widely used as a biodegradable solvent in various industries due to its low toxicity and environmental compatibility. It is commonly employed in the formulation of paints, coatings, and inks, where it helps improve solubility and drying times while replacing more harmful organic solvents. In the electronics industry, ethyl lactate serves as a cleaning agent for semiconductor wafers and circuit boards because it effectively removes residues without damaging sensitive components.

It is also used in the pharmaceutical sector as a solvent for drug delivery systems and in the synthesis of active pharmaceutical ingredients. In cosmetics and personal care products, ethyl lactate acts as a mild solvent and fragrance carrier, suitable for sensitive skin formulations.

Additionally, it finds application in the food industry as a flavoring agent, contributing fruity or creamy notes to products. Its ability to dissolve both polar and non-polar substances makes it valuable in chemical synthesis and extraction processes, especially in green chemistry initiatives aiming to reduce environmental impact.
