**Surelease** ®

Surelease ® is a family of fully formulated, aqueous dispersion products which constitute plasticized aqueous dispersions of EC with 25% ( *w*/*w*) solid content available in four types: E-7-19029, E-7-19030, E7-19040, E-7-19050. They are plasticized (depending on type) with dibutyl sebacate (3.5%-E-7-19029, E-7-19030) and oleic acid (1.9%-E7-19040). Surelease ® is produced in the following steps: EC is blended with plasticizer, then extruded and melted. The molten plasticized EC is then directly emulsified in ammoniated water in a high-shear mixing device under pressure. Ammonium oleate is formed in situ in order to stabilize and form the dispersion of plasticized EC particles. Then, purified water is added to achieve the final solids content. Applications of Surelease ® include beads and particles coating, matrix granulation (the dispersion can be used as a binder in wet granulation for the production of free-flowing granules, which can subsequently be compressed into tablets), taste-masking coating, or nutritional enteric coating [25].
