I tried a local vendor recently and made a few jar candles. They turned out better than expected. After getting my feet wet I wanted to purchase 50 Ibs. of soy wax. I narrowed my choices to Golden Brands,EcoSoya,or Cargill NatureWax. I was leaning towards a 100% pure soy wax like EcoSoya but am unsure what"carefully selected botanical oils" means? This doesn't sound very pure? I know some have a lot of frosting or top problems. Any suggestions would be appreciated. Thanks!
