Talk:Hydroquinone

message: The article doesn't mention anything about hydroquinone being used for cosmetic purposes, and that it is the main ingredient in fading/bleaching creams which are widely available in drugstores (at least in the U.S.) with 2 percent hydroquinone (prescription creams contain 3, 4, 5 percent). The article doesn't mention how it "reduces the color of the skin" (it inhibits the production of melanin). Those are just some of the points that should be covered. --Inahet 05:31, 18 July 2006
Hydroquinone does not inhibit the production of melanin; it inhibits the production of tyrosinase, which is an enzyme that triggers melanin production.  —Preceding unsigned comment added by 69.4.4.54 (talk) 00:23, 14 August 2008 (UTC)

thread_title: Alleged use by Michael Jackson

message: I've added a relatively brief reference to hydroquinone's role in the use of bearberry as an anti-bacterial treatment. It'd be useful if the article explained how hydroquinone is understood to interfere with bacteria. (Unfortunately, I didn't come across any information.) This part of the article would benefit from a better reference, too. Pololei (talk) 22:24, 12 May 2012 (UTC)
replies: text: the link you added is to a source that sells stuff, which is what I would consider spam.  I am sure that you did not intend it that way, but we try to avoid sites like that.  I just do not think that this commercial link is a very reliable source that bearberry contains hydroquinone.  Our article Arbutin does cite at least one decent (not perfect but primary) reference on a derivative of hydroquinone in bearberry.  But it is not hydroquinone itself.  So your edits might be modified strongly. --Smokefoot (talk) 23:23, 12 May 2012 (UTC)

The reason for my edit was readability. According to the Google Search my version is over 34 times more common in books. I am not a native English speaker but know about 20000 words, and yet "by two main routes" was not clear to me. Wikipedia should be for everyone, and the mere existence of Simple English Wikipedia should not be an excuse to make our articles hard to understand. Are you afraid that something can be too easy for native speakers? Keep in mind that non-native speakers now outnumber native speakers by a ratio of 3 to 1 (check it out), and some of them are Wikipedia editors, like me. So, why not make life easier? 85.193.252.19 (talk) 21:45, 7 October 2021 (UTC)

thread_title:  What was wrong with my reverted edit? 

message: Hydroquinone is polar according to various texts despite its symmetry, this is partially because of restricted rotation of the hydroxyl groups due to Partial Double Bond Character, causing them to be in the plane of the Benzene, and also because the two hydroxyl groups point in the same direct. 
The correct structure (or one of its correct structures/ conformers) of hydroquinone will have both -OH in same direction
