E-GRADE® Choline Hydroxide is a clear aqueous solution with a high pH and a mild odor. It has a very low corrosion rate on copper and other metallic surfaces and has been demonstrated to effectively remove both positive and negative photoresists. The product is an effective replacement for TMAH and is available in higher concentrations than TMAH in both water and organic solvents (for R&D). The combination of low corrosion rates, photoresist removal, etching, and lower toxicity makes E-GRADE® Choline Hydroxide an effective, safer-to-handle alternative to TMAH in next-generation semiconductor cleans, with performance enhancements such as faster photoresist removal rates and selective metal removal rates.

JEFFSOL® AG 1555 carbonate is 40 CFR 180.950 and List 4A (minimal risk classification) approved for use in agricultural pesticide formulations. It is a clear, mobile, hygroscopic liquid at room temperature. This product is an excellent solvent for many organic and inorganic materials. It offers excellent performance as an adjuvant enhancement agent in agricultural pesticide formulations. JEFFSOL AG 1555 carbonate can be used as a formulation component for tank mix adjuvants and as a solvent/co-solvent in emulsifiable and microemulsifiable concentrate formulations.
