I have recently bought some clothing which has a sticker attached to it stating that the clothing material was tested for harmful substances under OEKO-TEX® Standard 100. I have never seen this before so I did a bit of research.

Looking at the website, I have found that OEKO-TEX® is a Swiss company and standard 100 takes account of "important legal regulations, such as banned Azo colourants, formaldehyde, pentachlorophenol, cadmium, nickel, etc."

I have looked up Pentachlorophenol and according to TÜV SÜD

Pentachlorophenol (PCP) is a group of polychlorinated compounds used as preservatives for wood, leather and textiles to protect against the attack of moulds, fungus and bacteria.

PCP is toxic to human and the environment, in particular to aquatic life. Acute inhalation exposure to PCP in humans may affect the cardiovascular system, blood, liver, and eyes. PCP is also suspected to be carcinogenic. When PCP-treated articles are burned, highly toxic chemicals such as dioxins and furans may be released.

I am in the UK and our country is not in the list of countries which have restrictions on PCP provided on the TÜV SÜD website.

I can understand that PCP could be harmful whilst the textiles are treated with PCP, but is PCP in textiles actually harmful when worn after the PCP has been applied?
