Description
Butyl lactate is a biodegradable solvent derived from lactic acid and butanol. It appears as a colorless to pale yellow liquid with a mild, fruity odor. This solvent combines strong solvency power with a low evaporation rate, making it ideal for both industrial and environmentally friendly applications.
Manufacturers use butyl lactate in cleaning products, coatings, printing inks, and agrochemical formulations. It dissolves greases, resins, and polymers effectively. Additionally, it performs well as a co-solvent in water-based systems. Because of its low toxicity and renewable origin, it fits easily into green chemistry and bio-based product lines.
Thanks to its mild odor and strong performance, formulators prefer it in sensitive applications. It also serves as a carrier solvent for active ingredients and enhances wetting and flow properties in many systems.

Industries of Use
Industrial and Institutional Cleaning:
Butyl lactate breaks down tough soils and residues. It works in both acidic and neutral pH cleaning systems. Its low volatility reduces inhalation risks in confined spaces.
Paints, Inks, and Coatings:
This solvent improves paint leveling and pigment stability. It replaces traditional glycol ethers in many low-VOC coatings.
Agrochemical Industry:
Formulators use butyl lactate to deliver active ingredients in herbicides, fungicides, and insecticides. Its biodegradable nature makes it safer for soil and water systems.
Electronics and Metalworking:
Precision cleaning applications rely on it for safe and efficient degreasing. It removes oils without damaging sensitive components.
