数据库记载的用途

  • CIR ingredient: Methylene Chloride
  • Methylene chloride is predominantly used as a solvent in paint strippers and removers; as a process solvent in the manufacture of drugs, pharmaceuticals, and film coatings; as a metal cleaning and finishing solvent in electronics manufacturing; and as an agent in urethane foam blowing. It is used as an extraction solvent for spice oleoresins, hops, and for the removal of caffeine from coffee. However, due to concern over residual solvent, most decaffeinators no longer use methylene chloride.
  • In US industries, the process use of methylene chloride ended in the mid-1990s; [PMID 24224613] Methylene chloride standard (29 CFR 1910.1052) requires medical surveillance if >action level >30 days/yr of >STEL >10 days/yr;
