Esters, Other


Colorless liquid with a mild sweet odor; [HSDB]


Used as a flavoring agent and plasticizer for vinyl resins, rubber, and cellulosic resins; Also used to make resinous and polymeric coatings and paper/paperboard for use in contact with food; [HSDB]


Emergency treatment: "Irritants"; No observations of skin irritation or sensitization in study with 59 volunteers; Intravenous dosing of cats and rabbits caused dose-related drop in blood pressure (found to be caused by cardiac inhibition); Other effects noted in high-dose animal studies by different exposure routes include decreased weight gain, decreased hemoglobin (no indication of aplastic anemia in bone marrow smears), and neurological effects (i.e. local anesthesia and blockage of neural transmission); No evidence of mutagenicity and limited evidence of cytotoxicity; [HSDB] Causes somnolence in lethal-dose feeding studies of rats; [RTECS] Safe to use as a flavoring agent in food; [JECFA]
