Vybar Dispersion is a wax additive which is made from the same polymer as vybar, and is used as a substitute for Vybar 260.  It is used in the same way as stearic acid, to harden paraffin wax and help it to shrink while cooling for better mould release, and it also helps greatly with scent throw.  It will also increase your candle's melting point, and it will make the wax more opaque.  It is recommended for use in container candles, and with silicone and polyurethane moulds as it will not corrode the mould as stearic acid will do.  Recommended usage up to  3%.  Overloading wax with vybar will trap the fragrance in your wax and decrease the scent throw.
