Soyology candles are made from a blend of soy wax, and I think soy is supposed to be better for you, although I have no idea why. My primary interest in Soyology is the price: $12 for an 8 oz jar with a lid. Perfect!
Venus is described as an "intoxicating blend of a true Mediterranean orange blossom softened by subtle citrus notes". It is mostly orange blossom, and just the way I like it: dry, slightly bitter, just a touch of citrus. The throw is excellent, and it burns clean.
