Recently, many Central American countries recalled the two brands for containing high rates of diethylene glycol (4.6 percent), a chemical commonly used in antifreeze and brake fluid that has been banned in Vietnam for use in cosmetics and food.

At least 51 people died in Panama since October after taking medicine contaminated with diethylene glycol.

Just several days ago, Nicaraguan police seized 6,000 tubes of the two aforementioned brands.

All US imports of Chinese toothpaste were halted last week to test for the substance.

Also on Monday, the Vietnamese health ministry asked authorities to continue inspecting and seizing lipsticks of unclear origins after many Chinese lipsticks were found to contain sudan, a colorant which could cause cancer.
