Hong Kong Consumer Council reveals 60 shampoo samples that were found to contain tainted substances such as 1,4-dioxane at a press conference yesterday. The presence of 1,4-dioxane was detected in 38 shampoo samples with the amount ranging from 1.1ppm to 24ppm, which all fell within the mainland’s limit of 30ppm. Nonetheless 7 of the smaples had a 1,4-dioxane content between 12ppm and 24ppm, exceeding the EU safety standard (10ppm) for cosmetics. In normal usage, however, these models are not deemed to pose safety risks to users, said the council.   Xinhua
