Danish biocide study clears clothes
02/05/2014
Its analysis included a total of 34 samples, the majority from clothes made of cotton, with samples of wool and silk included too. Two active substances showed up in the tests, formaldehyde (used as a bactericide) and permethrin (used as an insecticide).
Formaldehyde was detected in seven samples in fairly low concentrations (between 3 and 3 mg per kilo of fabric), while permethrin was detected in two samples at concentrations of between 367 and 407 mg per kilo. Formaldehyde was detected in samples of cotton, wool and silk, while permethrin was detected in wool only. For both formaldehyde and permethrin is the environmental protection agency’s conclusion that there is no cause for concern for health effects.
