CHINA will reveal the standard method for testing diethylene glycol (DEG) in the toothpaste by the end of this year, Beijing Business Today reports.

Experts from product quality inspection authorities in Beijing and Jiangsu Province have submitted a draft method for review and approval to China's Standardization Administration, the national body in charge of setting and enforcing product standards, the report said.

The method will address China's lack of standards for testing DEG levels in toothpaste, the report said.

When the compulsory standard is approved, inspection officials will apply it to determine whether the quantity of DEG is safe, the report said.

China has banned DEG from being used in toothpaste after several countries, including the United States and Japan, stopped importing and recalled Chinese-made toothpaste found to contain DEG, which is harmful to the kidneys.

DEG, a chemical often used as antifreeze, will also be phased out by many domestic producers who use it to sweeten toothpaste, the report said.

China has adopted many measures to respond to the quality crisis facing Chinese toothpaste since it was first exposed in June. In July, the General Administration of Quality Supervision, Inspection and Quarantine banned DEG from being used to produce toothpaste and prohibited importing or exporting toothpaste containing the chemical.
