What's the difference? If you're talking about a 100% coconut product and not one of the many mystery blends currently being marketed as "Coconut wax" ...
You can buy 100% Coconut Wax , a soft, white, solid from Cargill composed of Hydrogenated coconut glycerides" with a MP of appx 90-102 degrees or you can buy Coconut Oil 92, a soft white solid, from a soap supplier like Bulk Apothecary composed of Hydrogenated coconut glycerides with a MP of appx 92 degrees. If there's a difference between those 2 products, aside from the name, I can't tell what it is.
I blend 100% coconut oil (or wax, if you prefer) with soy - the soy used and the ratio of coco:soy take some tweaking to get good results for sure. It's not a magic bullet. Too much coco does not a better candle make.
