Talk:Polydimethylsiloxane

Question for the caretaker(s) of this page: in the Chemistry section, the page says: "The chemical formula for PDMS is (H3C)3[Si(CH3)2O]nSi(CH3)3..." . Shouldn't this be "(H3C)3 Si O [Si(CH3)2O]nSi(CH3)3" ? my chemistry is alittle rusty but I think this needs to be there. (?true?). - lanephil, 2/25/08 —Preceding unsigned comment added by Lanephil (talk • contribs) 18:58, 25 February 2008 (UTC)

Are there also NON-organic polymers? I mean, because I think ALL polymers are organic, the word 'organic' in the first sentence is not necesary...

There are. As water is removed from phosphoric acid, for example, it becomes a long-chain polymer (see polyphosphate). One can also think of glass as a branching polymer with a backbone similar to silicone (a polysilicate). I'm sure there are other examples as well. But you're right that structural polymers are usually organic.--Joel 20:44, 12 April 2006 (UTC)

What's the Absorption Coefficient?

It's "optically clear"...... Anyone might know about this?

skin lotion

Dimethicone (1%) is listed as the "active ingredient" for "skin protection" in "CVS advanced hearling fragrance free lotion"; should skin something be mentioned as an application? Mike Linksvayer 21:02, 13 March 2007 (UTC)

Yes, its widely used as a skin protectant. I've added this in the article.

its also used in lubes.. pjur and probably others. trying to get some info on it when i found this page. more info on its safety would be welcome.

More than what? More than where it says it "is generally considered to be inert, non-toxic and non-flammable" and that "The Cosmetic Ingredient Review's (CIR) Expert Panel, has concluded that dimethicone and related polymers are 'safe as used in cosmetic formulations' [1]"? What are you looking for exactly? Some citation that it's actually not safe? I guess we could make one up for you. Here you go: [2]. 198.49.180.254 20:12, 14 September 2007 (UTC)

where can u find the history of this chemical at? like when it was discovered etc.? —Preceding unsigned comment added by 74.194.145.34 (talk) 03:39, 15 October 2007 (UTC)

Breast Implant Usage Safety Concern

What were/are the concerns with Polydimethylsiloxane's safety as a breast implant filler? The article is vague and I'd like to know more about them.24.83.148.131 (talk) 10:38, 25 May 2008 (UTC)BeeCier

Other Synonyms for Polydimethylsiloxane

I was looking on the web for info on the additive methyl silicone which was listed as an ingredient on my juice bottle. It turns out that it is just another synonym for Polydimethylsiloxane. Other synonyms are dimethicone, dimethyl silicone, methylpolysilicone and simethicone. Can someone edit the article to include these? Thank you.24.83.148.131 (talk) 10:43, 25 May 2008 (UTC)BeeCier
