1,1-Dichloroethylene, commonly called vinylidene chloride or 1,1-DCE, is an organochloride with the molecular formula CCl2CH2.
It is also used in semiconductor device fabrication for growing high purity silicon dioxide (SiO2) films.
During the 1990s research suggested that, in common with many chlorinated carbon compounds, Saran posed a possible danger to health by leaching, especially on exposure to food in microwave ovens.
[5] The health effects from exposure to vinylidene chloride are primarily on the central nervous system, including symptoms of sedation, inebriation, convulsions, spasms, and unconsciousness at high concentrations.
[6] International Agency for Research on Cancer has put vinylidene chloride in Class 2B, meaning possibly carcinogenic to humans.
