Diisononyl phthalate (DINP), a common plasticizer, can be found in various consumer products; however, some say it is dangerous to health, and California recently decided to add it to its list of more than 900 potentially dangerous chemicals that consumers should know are in the products that they use regularly.
A state advisory council advised the California Office of Environmental Health Hazard Assessment (OEHHA) to add DNIP to its list. The advisory panel, called the Carcinogen Identification Committee, said scientific evidence showed the chemical could cause cancer, Bloomberg BNA reported. The addition of DINP to the list means businesses will have to provide clear warnings when it exposes the public to an unsafe level of the chemical, the source reported. The OEHHA is tasked with determining what a safe exposure level is for DINP.
DINP is used in some vinyl flooring, wire and cable insulation, coated fabrics, garden hoses, automobile undercoatings and roofing materials, according to Bloomberg. The California advisory panel said research on animals said exposure of the chemical could lead to islet cell tumors of the pancreas and mononuclear cell leukemia in rats, testicular cancer and kidney tumors in male rats and uterine tumors in female rats, the source said.
CPSC report details DINP dangers
DINP exposure is likely to occur from the use of flexible plastic items, which includes certain toys children may chew on, a report from the Consumer Product Safety Commission said. Humans can be exposed to the chemical orally or inhale it. The report said other products containing the chemical are sandals and rainwear.
Chronic exposure to DINP can lead to spongiosis hepatis, a degenerative lesion of the liver, the report said. Test on rats also showed renal and skeletal abnormalities occurred when the rodents were exposed to the chemical.
“DINP is clearly carcinogenic to the rodent, inducing hepatocellular carcinoma in rats and mice of both sexes, renal tubular carcinoma in male rats, and mononuclear cell leukemia in male and female rats,” the report stated.
