  • Applications

    Chemical name: 2-Ethylhexyl L-(+)-lactate; CAS number: 186817-80-1. 2-Ethylhexyl L-(+)-lactate is mainly used as a solvent and plasticizer in polymer systems and formulations, particularly in coatings, inks, and adhesives, offering good solvency and compatibility with a range of polymers. It is also used as a plasticizer for polylactic acid (PLA) and other biopolymers to improve flexibility and processing. In cosmetics and personal care, it serves as a solvent and emollient, enhancing formulation feel and stability. In household and cleaning products, it acts as a mild solvent, aiding dissolution of difficult-to-dissolve constituents and improving formulation blending. In industrial manufacturing and coatings, it can be used as a processing solvent and additive for plastics and adhesives, supporting processing and end-product properties.
