This is a blended wax that contains a soy-based additive and is both FDA-approved and Kosher-certified. The additive enables the soy to be poured at hotter temperatures reducing frosting and increasing the fragrance oil load. It blends well with paraffin, slack wax, and microcrystalline waxes. 444GW has a higher melt point which enables it to retain a higher fragrance oil load to give you a stronger scent throw. Comes in flake form. Pour temperature is 125 - 145 degrees F; and fragrance oil load is 9 - 11%.
