3.Application scope and Usage
Ethyl L-Lactate is a safe and non-toxic natural ester compound. It is widely used as a food flavoring agent (FEMA 2440, for fruit flavoring in candies, dairy products and beverages), a pharmaceutical solvent (in line with USP/EP standards, for drug carriers and topical preparations), a cosmetic additive (for perfumes, skin care products), and an environmental-friendly industrial solvent (for inks, paints, electronic cleaning).
4.Package and Storage
Ethyl L-Lactate is packaged in 25kg dark HDPE drums or stainless steel drums with a food-grade inner PE film liner. It should be stored in a cool, dark place (< 25℃), tightly sealed to prevent moisture and oxidation, and kept away from fire sources and strong acids. The shelf life is 24 months.
