Talk:Benzoyl peroxide

message: "Benzoyl peroxide works as a peeling agent, increasing skin turnover and clearing pores, thus reducing the bacterial count there as well as directly as an antibacterial." Reducing baterial count where? It may be restated as "Benzoyl peroxide works as a peeling agent, increasing skin turnover and clearing pores. This mode of action may reduce acne symptoms, as well as by acting as an antibacterial". (I would change it myself, but I'm not sure that was the original intent, and there's no citation.)--Ryuns (talk) 01:30, 30 July 2008 (UTC)

message: Requesting chemical properties of Benzoyl peroxide. Could not find any factual properties anywhere. -Masterhomer
Shouldn't Benzoyl peroxide be more under a drug then a chemical? So rather then have a chembox won't a drugbox be better? If no disagreement will do it shortly. —The preceding unsigned comment was added by Crislee 88 (talk • contribs) .
:Well, it does have other uses, e.g. as an industrial catalyst for radical polymerization, and the chembox looks pretty good to me, but if you can make the drugbox look just as good I'd be fine with that. Go for it. —Keenan Pepper 15:50, 29 June 2006 (UTC)

text: OK. The page is changed like it is. I'll check back in some unspecified while to see if there has been a source provided for the mutanogenic/carcinogenic at low concentrations company fact. I did change it from "found to not be" to "not found to be". Added to "appurtenances" in wiktionary too! Menswear 16:48, 1 September 2007 (UTC)

I thought half-life was only for radioactive material —The preceding unsigned comment was added by Mdk0642 (talk • contribs) 01:52, 27 January 2007 (UTC)
replies: text: No, half life can be applied to anything which is undergoing depletion, normally by a decay mechanism. Also, the "solubility" physical parameter is given as "poor". This doesn't make sense unless it is specified what solvent is being referred to.--129.94.6.29 06:55, 24 July 2007 (UTC)
replies: text: Just curious, could we preface this with a "This substance tends to decompose quickly in heat. ... rest of section" to the section?

thread_title:  Half-life???? 

message: is it possible for this cream to scar the face after severe burning has taken effect?
:Anything can theoretically happen, but I've never heard of such a thing. Some people are allergic to it, but I've never, ever heard of a permanent scar forming at therapeutic concentrations. Normally, the absolute worst you could get would be a very superficial burn which heals without any problems. The chemical decomposes at the very surface of the skin, so deep burns necessary to causes scarring are essentially unheard of.WolfKeeper 00:10, 2 March 2007 (UTC)
thread_title:  scar? 

message: If someone has the knowledge, can they please show results if one were to ingest such a chemical formulation. There just appears to be a burning curiosity of mine, to as the causes of doing such a thing can lead to, in relation to the long-term effects or how other organs / parts of the body react negatively.

thread_title:  Consuming the compound 

message: I removed this bogus claim that a) benzoyl peroxide removes the top layer of skin, b) benzoyl peroxide and sunscreen together can work as an anti-aging treatment:
Benzoyl peroxide removes the top layer of skin, which also decreases the sun protective effect (roughly SPF 3). This can cause sunburn and premature aging if sun protection is not worn. If sun protection is used, benzoyl peroxide has effects similar to glycolic acid peels which are so-called anti-aging treatments.

replies: text:  Yeah, it's pretty well documented that it makes your skin more susceptible to UV damage and sunscreen would prevent that to an extent.  But as an anti-aging treatment?  I have my doubts dearly (talk) 21:40, 7 March 2008 (UTC)

thread_title:  Removed advertisement-laced external reference 

message: "Benzoyl peroxide breaks down in contact with skin, producing benzoic acid and oxygen, neither of which is significantly toxic."
If the chemical is a possible mutagen (as stated earlier in the article) the safety of its breakdown products is not relevant and serves only to lull the reader into a false sense of security.  For example, hydrogen peroxide breaks down into water and oxygen, two substances that are harmless, but prior to its decomposition it is corrosive, carcinogenic and toxic.  24.65.95.239 (talk) 00:12, 4 January 2009 (UTC)
thread_title: Irrelevant/Misleading Claim

message: This statement is not supported:
Research suggests that 5 and 10% concentrations are significantly more effective than 2.5%, but 2.5% is usually better tolerated.[5][6]
Reference 5 states in the abstract:
The 2.5% benzoyl peroxide formulation was more effective than its vehicle and equivalent to the 5% and 10% concentrations in reducing the number of inflammatory lesions (papules and pustules). 
6 only compares 2.5 and 5%, and states both are highly effective (I don't have access to the full text, however). Here's a 2009 reference supporting equivalence:
http://www.ncbi.nlm.nih.gov/pubmed/19588642
I'm changing this later if no one raises any objection.  — Preceding unsigned comment added by Jkom329 (talk • contribs) 20:30, 26 February 2011 (UTC)
thread_title:  2.5 is as effective 

message: The study cited states that "Desquamation, erythema, and symptoms.of burning with the 2.5% gel were less frequent than with the 10% preparation but equivalent to the 5% gel.

thread_title: Toleration (2.5% vs 5% vs 10%) 

message: Benzoyl peroxide is used as a special effects explosive as it is relatively safe with much lower blast effects than many other explosive substances. A benzoyl peroxide explosion is also attractive for filming as it produces a deep orange flame and thick black smoke. Roger (talk) 15:59, 22 March 2012 (UTC)
thread_title:  Use as an explosive in film and television special effects 

message: The infobox describes the chemical compound (ie. in its pure form) and list it as explosive etc.). I think its strange and misleading to include the pharmacology data in the infobox too, because it is not for the chemical but for some solution (or whatever) of it. For the same reason the  warns against putting chemical data in the the drug boxes. Christian75 (talk) 17:46, 7 July 2015 (UTC)

thread_title:  And Benzoyl hydroxide? 

message: The first sentence says benzoyl peroxide has a structural formula . Now I haven't taken chemistry since high school but I don't know what "Ch" is, and looking elsewhere on the web I'm suspecting it's a typo and should be . If someone else can confirm, can it please be changed? (I don't want to change it myself since I'm not a chemist and therefore not 100% sure.) Mjbaldwin (talk) 04:50, 11 October 2020 (UTC)
thread_title:  Chemical formula? 

message: In the section "Synthesis, structure, and chemical reactivity" there are two chemical equations for two different methods of producing benzoyl peroxide. However, the second half of the second equation seems to have been copied wholesale from the first equation. The second synthesis starts with benzoyl chloride and hydrogen peroxide, but for some reason in the products there is barium chloride. I believe the products should be 1 mole of benzoyl peroxide and 2 moles of hydrogen chloride, but I'm not a chemist and would love it if one came along to correct the equation.
