About the Product

EXTRA has developed MDAWO technology (Multiple Degree Amphiphilic Wash-Out technology) and applied it to processes. The process of technology, the DVS component is completely removed and none of un-cross linked DVS is detected. In general, the crosslinking process is carried out using DVS having a purity of about 95% for BDDE used for crosslinking HA and 97% or more purity for EXTRA. By using highly pure crosslinking bridge, crosslinking ratio is high, and high quality products can be produced.

EXTRA filler has it's own Third Step Cross linking(TSC) maximizes viscosity through a patented 3step microbeads process. The technology to increase cross-linking rate, it has increased the sustainability of HA.
