GW 464 is a good quality soy wax produced by global wax giant AAK under the Golden Brands name.
With a melting point of 45-48C, it is a natural replacement for the discontinued CB-135, CB-Advanced and CB-Xcel blends.
CL and Stabilo wicks tend to work best in this wax, with a 30cl candle requiring a CL17/CL18 or Stabilo 16/18. This will of course depend on fragrance.
The wax will hold 10%+ of most fragrances and more with polymers such as Vybar or Varaplus, although higher scent loading doesn't always equal better throw. In reality, it is usually pointless adding more than 8% or 10% oil. A better option would be to choose another fragrance.
Pour temperatures should be reasonably high (65-75C) depending on container geometry. As ever a warm ambient temperature (20C), warm glassware and the prevention of rapid temperature changes during cooling will reduce the likelihood of polymorphism/frosting. This wax is prone to circular surface cracking, but this can usually be reduced/eliminated by good temperature control.
