What is Ethyl Lactate?

For most people, ethyl lactate is a very unfamiliar term. In fact, it is a colorless liquid. It has a little smell when you smell it close to your nose. It is said that ethyl lactate will dissolve in water and then produce organic matter. It should be reminded that ethyl lactate is a flammable substance and is prone to explosion, so it must be stored and transported with special caution. The following is a detailed introduction to this chemical substance.
