Description

Butyl lactate (CAS 138-22-7 ), also known by its FEMA 2205 designation, is a slow-evaporating ester solvent derived from lactic acid used across industrial, cosmetic, and food applications. It combines strong solvency with low toxicity, making it a preferred alternative to conventional petrochemical solvents in formulations requiring a more favorable regulatory and environmental profile. In coatings, inks, and polymer processing, it dissolves resins, nitrocellulose, and cellulose acetate butyrate where controlled evaporation rate and film quality are critical for the final product. Personal care formulators use it as a carrier solvent in nail care products, fragrances, and skin formulations where compatibility with active ingredients and low irritation potential drive solvent selection. As a flavoring agent, it contributes buttery, creamy top notes to food and beverage products including dairy analogs, baked goods, and confectionery. It also functions as a plasticizer and coalescing agent. Butyl lactate is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for high-volume industrial buyers. Standard commercial grades include technical grade for solvents. Food and flavor grades meeting specific purity specifications are available for sensitive applications. Kosher and natural-origin certified material is available from select producers to support clean-label positioning. Contact us for supply of Butyl lactate Request Quote
