Talk:Octamethylcyclotetrasiloxane

Environmental concerns

I opened the report cited by the text, and the report summary does not specifically support the text (and I was not willing to purchase the full report). I also added another source and balanced the text, and made consistent with the wiki re D5. Comments welcome. Journalist1983 (talk) 01:58, 18 November 2015 (UTC)

Looks good to me. Many people who contribute to Wikipedia can only access Google-able sources, which are typically focused on various tox and environmental themes, much of which is not very good science. The good literature is almost all behind paywalls or requires that one physically visit a pretty high powered library. --Smokefoot (talk) 01:32, 23 November 2015 (UTC)

My comment to D₅ is also valid here. A UK RAR for D₄ also exists. (Likewise for D₆.) --Leyo 11:28, 23 November 2015 (UTC)

Smallest stable cyclic siloxane

In the article, D₄ is characterized “as the smallest stable cyclic siloxane”. However, D₃ is also rather stable, as it is quantifiable in the environment and commercially available (see also de:Hexamethylcyclotrisiloxan). Unfortunately, Google Books preview does not work for me in this case. Smokefoot, could you please double-check the cited reference? --Leyo 09:19, 18 July 2018 (UTC)

Possible conflict of interest?

There have been a number of edits made by a person with the IP address 98.160.94.5 that seem to downplay the risk octamethylcyclotetrasiloxane poses to the environment. That same IP address has made edits to the page of Laurie Ann Goldman which according to the Wikipedia page joined the board of New Avon LLC in August 2018. Avon Products is a multinational cosmetics company, and Goldman became the CEO of New Avon LLC in January 2019. I believe that the person behind 98.160.94.5 could be Laurie Ann Goldman. This is further supported by the fact that Goldman is of Jewish heritage and two edits were made to the Yiddish page by the same IP.

I'm unfamiliar with the rules of Wikipedia, and I would like to ask someone who knows this to help me out. The problem as I see it is that Goldman made these edits while employed by a cosmetics company. The chemical industry, which includes the cosmetics industry, is well known for lobbying against rules and regulations on chemicals. Does this make the edits problematic, or are there no rules against this on Wikipedia?

Pinging Leyo as you seem to be active on this page. --Tidalcargo (talk) 19:06, 3 August 2021 (UTC)

The edits by 98.160.94.5 are several months apart. Thus, it is likely that they were made by different persons.

In the article it still says that D₄ is a SVHC in the EU due to its PBT and vPvB properties. You are of course welcome to expand the article. --Leyo 22:59, 3 August 2021 (UTC)

I agree that my scenario isn't very convincing, but for what it's worth the address is listed as a likely static IP here: https://whatismyipaddress.com/ip/98.160.94.5

Either way, thanks for taking a look at this. --Tidalcargo (talk) 09:08, 4 August 2021 (UTC)

Ok, I just checked whether the website correctly reports my own IP as dynamic or static, and it incorrectly reports both my IPv4 and IPv6 as static. So please disregard my previous point on the IP being static. --Tidalcargo (talk) 11:13, 4 August 2021 (UTC)
