You should be able to find a silicone list at this link
The conditioner you are using is loaded with cones (Cyclopentasiloxane and dimethiconol), so you'll need to shampoo those out and start over with another kind (sorry!). I have found that drugstore.com lists ingredients, and walgreens.com usually does too, so I check out a lot of products before going to the store. If you want a recommendation for a new condidtioner, most people here like suave naturals, which have no cones. As for gels, you can find a lot of info searching the boards, especially the product review one.
