Organophosphates, Other
Slightly yellow liquid with a sweetish odor; [HSDB]
Used as a plasticizer for resins and elastomers, in floor finishes and waxes, as a flame retardant, as a plasticizer for rubber stoppers in blood specimen containers, and as a fire-resistant and light-stable plasticizer for products intended for food contact; Occupational exposure is likely to be by skin absorption during production and from floor polishes; [HSDB] Used as solvent for resins, a viscosity modifier in plastisols, and an antifoam agent for synthetic rubber, plastics, and lacquers; [INCHEM]
Irritating to skin and eyes; The liver is the target organ in high-dose animal studies; Has anticholinesterase action at lethal doses; Skin absorption is expected to be low; No effect on neuropathy target esterase (NTE), but cholinesterases were inhibited in treated hens; [HSDB] An irritant; [MSDSonline]
