So I want to add new scents to my candle line.. and decided to get into using essential oils... I’ve been testing soy wax but definitely want to get into mixing it with coconut wax... has anyone mixed soy and coconut wax and if so how has it worked out for you? ( I ordered it anyways to test but just curious). Also does anyone know of a good website to get essential oils in 16oz bottles or larger..? also, does anyone know a of a good formula to add essential oils? I understand that essential oils and fragrance are different in amount. But can not seem to see a formula instead of amount of drops.
