Talk:P-Phenylenediamine

message: It seems the person who wrote this article is more interested in pushing the organic or natural viewpoint than providing straightforward information about this chemical. I would prefer a more straighforward listing of chemical properties.
-Agree. I think this deserves a flagging for not being in the style of a Wikipedia article, too. 87.114.22.50 18:21, 30 September 2006 (UTC)

replies: text: I corrected two different places where the article cited sources but then said exactly the opposite of what the sources said, or worked to give the impression that the chemical was carcinogenic in spite of the cited sources. I also removed some text on the EPA that was plainly copied word for word from sites calling for the EPA to declare the chemical a carcinogen. It would be up the FDA to regulate its use in hair dye and cosmetics in any case. Someone is hell-bent on pushing a viewpoint in this article.173.228.123.116 (talk) 12:45, 20 February 2011 (UTC)

message: For those of us that are allergic to ppd, the alternatives that are sited in this article are a great resource. I personally appreciate it greatly, regardless if someone thinks it is or is not keeping with wikipedia 'type' articles. 70.197.229.109 (talk) 23:07, 27 June 2008 (UTC)
replies: text: Wikipedia is not intended as a medical guide or a manual on your health, aside from the fact that knowledge is healthy.  My source indicates that PPD is not used in hair preparations anymore.--Smokefoot (talk) 14:44, 20 February 2011 (UTC)
replies: text:  What is your source for it no longer being used? I can walk into a shop and find several products listing P-Phenylenediamine in their ingredients. dramatic (talk) 01:16, 21 February 2011 (UTC)

text: Here is what I read "1,4-Diaminobenzene [106-50-3] (p-phenylenediamine) has been the main primary intermediaoutputte used worldwide for more than a 100 years but has nowbeen largely replaced by 2,5-diaminotoluene"  The source is ref 2 ("Hair Preparations" in Ullmann's Encyclopedia). Usually a very good source of info.  I should stop by the local shop and see what they list as ingredients. --Smokefoot (talk) 03:35, 21 February 2011 (UTC)
replies: text:  According to this article on Medical News, PPD is still used in 2/3 of all hair dyes: http://www.news-medical.net/news/2007/02/05/21700.aspx It is still legal in the EU as an ingredient in hair dye (although some member countries have outlawed this use), but has been outlawed as an ingredient in skin dye (tattoos). If you have any doubts, just try to find hair dye products (it is usually not used in extremely blonde dyes, since that is not adding new color) in stores or online, it is very difficult unless you want to spend at least 50% more. 70.36.142.97 (talk) 19:03, 23 February 2011 (UTC)
replies: text: Great find. Obviously someone is wrong somewhere.  I will tend to this article tonight or tomorrow taking the emphasis off the claim that PPD is no longer used.  --Smokefoot (talk) 19:14, 23 February 2011 (UTC)
