Detection of Diethylene Glycol in Toothpaste

Abstract

Toothpaste products are permanently used by consumers of different age groups for preventive, curative and aesthetic aspects to ensure the health and safety of the teeth. This encouraged valuable diversity in their production and commodity supply. The investigation results of DEG through laboratory tests of 22 brands showed that three samples, coded D3, D10 and D11, lacked using the gas chromatography GC technology, whereas other trademarks showed that they contain this toxic contaminants with concentration range between 101 - 839 ppm and were distributed on different origin, of which the German brand Crest2 topped the list and the unknown origin Colgate2 came at the bottom. Six Chinese-made sample pastes contain high concentrations of this toxic substance, despite doubts about the credibility of the origins included in the cards, which requires attention from competent control bodies to examine samples, especially with the current wave of fraud and the inclusion of the Chinese-made toothpaste with the DEG substance.
