Soy Wax discovered in 1991 as a newer alternative to paraffin wax.
It is a natural, renewable, non-toxic and biodegradable wax.
It is a hydrogenated form of soybean oil, available in flake form and has an off-white appearance, soy wax has a lower melting point than paraffin. Burns longer and at a cooler temperature than paraffin wax.
So that is the difference which may not seem much but it is.
My Opinion: I love these candles and the scent.
