Talk:Selenium disulfide

bogus reference

Side effect -causing tiredness - the reference leads no where that says anything about it. — Preceding unsigned comment added by 108.243.106.85 (talk) 17:02, 1 March 2021 (UTC)

Can anyone who has got the hang of disambiguation, do a redirect for Selenium sulphide If the redirect is done the other way around it will leave all those nevo alchemists in the new world colonies who never learnt proper 'English', as she is meant to be spoke -what with the greek roots and all- floundering around. (Is it any wonder George wanted to get shot of them?)--Aspro 23:42, 21 February 2006 (UTC)

Please check this link: http://www.epa.gov/IRIS/subst/0458.htm concerning the confusion between selenium(IV) sulfide and selenium disulfide. It would appear that for the purpose of carcinogenicity they are one and the same. I leave it to the experts to decide. —Preceding unsigned comment added by 68.154.32.24 (talk) 20:32, 3 September 2008 (UTC)

There are two chemical compounds, (the SeS₂ 8 membered ring has isomeric forms) - however as stated in the article proprietary formulations that analyse as SeS₂ are a mixture of ring compounds. The mixture depends on the method of production and the thermal history. I have not found a study of SeS_x as a carcinogen where pure chemical was used- sensibly in my view the workers take an as delivered formulation, which in some cases included elemental selenium. Note that oxidation state with ring compounds is pretty well meaningless it certainly gives no insight into the chemistry of these heterocyclic compounds. IMO both formulations of Se + S in proportions 1:1 and 1:2 should be treated as potentially carcinogenic, it may be that one is more potent than the other, but currently I do not think a decision can be made. Bearing in mind the reducing use of selenium compounds in shampoos I suggest that this qquestion is unlikely to be resolved in the near future. --Axiosaurus (talk) 08:04, 4 September 2008 (UTC)

Please note the statement:

"NOTE: This assessment is also for selenium disulfide (CASRN 7488-56-4)." on http://www.epa.gov/IRIS/subst/0458.htm

Both, selenium monosulfide and selenium disulfide are considered to be carcinogens (when taken orally.) —Preceding unsigned comment added by 158.111.4.26 (talk) 13:09, 4 September 2008 (UTC)

Melting and boiling points

I seriously doubt that the boiling and melting points listed for SeS₂ are correct. In fact, I know that they are not. Ses₂ is a solid at standard conditions. The MSDS from sciencelab.com [1] has the melting point at 121.5 °C. I'm not willing to say that this is the correct melting point, but it is probably close. Does anyone know the actual values? —Preceding unsigned comment added by Yokozunapete (talk • contribs) 19:05, 12 June 2009 (UTC)

Jmol image

The Jmol image given for this compound is S=Se=S, despite the page explicitly stating that it is not an analogue of sulfur dioxide (O=S=O) and rather is a ring-shaped compound. Should this be changed? If so, what should the new image be, since it's a non-stoichiometric compound? Xolroc (talk) 16:47, 2 March 2014 (UTC)

Cancer?

On my bottle of medicated shampoo, it says that Selenium Sulfide may cause cancer. Shouldn't there be a section on that here? 108.20.174.117 (talk) 21:39, 10 April 2020 (UTC)
