    Al Cass is not oil bsed, it is silicon based.Most of the store brand oils are rebottled Al Cass.

    Al Cass is Petroleum based - quoting from the bottle in front of me (untouched since I discovered Snake Oil) "contains petroleum distillates."

    Silicon is a petroleum distillate, I believe.

    No, silicone is silicone. Petroleum distilates are hydocarbon compounds such as diesel fuel, kerosine, gasoline etc which are distilled from crude oil. They have different boiling points and, because of that, can be separated from each other and crude by a distillation process.


    Silicon is the second most abundant element in the earth's crust, comprising around 28% of it. It is not found in its elemental form but occurs mainly as oxides and silicates. In contrast to carbon, silicon-silicon bonds are uncommon. Natural silicon-carbon bonds are extremely rare but they can be created synthetically.


    Sorry. I'm a bit of a chemistry geek. :roll:

    PS: I should add: Silicon is an element. Silicone is a synthetic material
    This is from a Silicone breast implant site:

    http://www.silicone-review.gov.uk/silicone/

    Silicones are synthetic polymers and are not therefore found naturally. They have a linear, repeating silicon-oxygen backbone akin to silica. However, organic groups attached directly to the silicon atoms by carbon-silicon bonds prevent formation of the three-dimensional network found in silica. These types of compound are also known as polyorganosiloxanes. Certain organic groups can be used to link two or more of these silicon-oxygen backbones and the nature and extent of this crosslinking enables a wide variety of products to be manufactured. The most important materials used in medical implants are fluids, gels and rubbers (elastomers) whose physical and chemical properties include, amongst others, a high degree of chemical inertness, thermal stability and resistance to oxidation.


    OK. That's enough! EEY GAD, I'm a nerd and a geek. I'll be quite now.

    Knowing actual facts about chemistry does not make you a geek.
    I stand corrected. Thank you for your erudite post.

    I just added to my post. I got cared away reading about it tonight. I already practiced and monday night TV is horrible. Thanks for peaking my interest and I really didn't mean to be rude if it came off that way.

    Actually, I did while you were writting your post. That is the correct thing to do.

    I think Al Cass is Silicone based. Which is a petroleum derived product.
    According to the web site you cited.

    Huh? I thought it established that petroleum products and silicon are different natural sources. Silicon is an element. What part of petroleum is elemental? What am I missing?
