[QUOTE="Orielensis, post: 3194679, member: 96898"]I wouldn't say "maybe less" but, whithout any doubt, "most definitely much less". I know about this debate, which at some point reached quite a media prominence and lead to a range of related studies. [URL='http://gov.personalcarecouncil.org/ctfa-static/online/lists/cir-pdfs/FR285.pdf']Here[/URL] is a 2001 safety assessment by the CIR ("Cosmetic Ingredient Review"), [URL='http://www.who.int/water_sanitation_health/dwq/chemicals/edeticacidsum.pdf']here[/URL] is the current WHO fact sheet on EDTA based on a similar study (summarized [URL='http://www.who.int/water_sanitation_health/dwq/chemicals/edeticacid.pdf']here[/URL]). Both studies came to similar results, I quote: "EDTA does not appear to be teratogenic or carcinogenic in animals. The vast clinical experience of the use of EDTA in the treatment of metal poisoning has demonstrated its safety in humans" (from the WHO fact sheet). Whether and to what degree to trust such studies is everyone's personal decision, I assume, but I generally do. That of course doesn't mean that the substance shouldn't be handled with great care, not swallowed, never left in reach of children, never used in a kitchen environment, etc. Thus, I do very well understand the general hesitancy you expressed, and will think of it should a similar topic come up here again. (By the way, I don't know if this the right place to express how grateful I am for your 1995 "Jitals" catalogue which I used just yesterday, but I nonetheless want to do so...)[/QUOTE]
