How can we tell solvent-based dressings from water-based dressings?

If the labels don`t mention it.

The appearance, whitish VS clear, seems to say nothing.

And about silicone content too, how can we tell?

Thanks.

Most bottles have warnings that they contain Petroleum Distillates. I believe by law they have to have chemical warnings on the bottles.

If they aren`t on the bottle, then the MSDS sheets should have that information on them.

Yeah, I also go by the petroleum distillates content. If it contains it, I`d say the dressing is not water based, and therefore is not a PDMS dressing like we try to use. PDMSs also look milky white in appearance. You can also usually open up these bottles and take a peek and whiff.

I`d be wary of clear dressings with pet. distillates, but I`m not sure any modern water based dressing would contain so-called "bad" silicones anymore.... Personally, I don`t sweat it and just stay away from the pet. distillates and the clear stuff. BTW, PDMS is a "silicone", just not one we should worry about.
