Ethyl Lactate

Ethyl Lactate is a highly safe organic solvent used also as a flavoring agent.

It is used in various fields as a green solvent that hardly affects the working environment and the natural environment when it is leaked.
Recently, the businesses of “Solvent used for photoresist in semiconductor production” and “sale of products for cleaning during the process of manufacturing liquid crystal panels” are growing inside and outside Japan.
In addition to the general industrial grade, we can provide the electronic industrial grade for which metal guarantee was conducted through analysis with ICP-MS. Please feel free to contact us.

Basic information

What is Ethyl Lactate?

Ethyl Lactate is colorless and clear and has a peculiar odor. It is mixed with water and many solvents. It is biodegradable and it also became popular as an organic solvent that has almost zero impact on working environments or on the environment due to leakage.

It has a high boiling point and low volatility and is often used in inks and polymer solvents. Also, it has been recently used as resistance diluents for semiconductor manufacturing processes. The demand for ethyl lactate as a detergent for the manufacturing process of LCD has been increasing.


  • Colorless and transparent liquid that has a faint odor similar to that of higher alcohols
  • Its molecule has a hydroxyl group and an ester group, and it can mix with water and most solvents freely.
  • It can dissolve a broad range of substances, including natural and synthetic resins and synthetic fibers.
  • When blended with mixed solvents, it can improve spreadability and workability.
  • Its evaporation rate is relatively low, so it can be used as a high-boiling solvent.
  • An ultrapure solvent whose metal content is low and that has been adopted for many electronic materials.
