BELSIL GB 1020 is a blend of low-viscosity dimethicones and a high- molecular dimethiconol. It combines the properties of the low-viscosity fluids and the extremely high-viscosity dimethiconol. The excellent spreading of the low-viscosity dimethicones allows a good distribution of the high-viscosity conditioning agent dimethiconol. BELSIL GB 1020 provides a water-resistant, but breathable non-occlusive protection barrier. This provides good substantivity and fixation of active ingredients. It provides lubricious feeling and a longer play time in formulations. BELSIL GB 1020 also yields sleek, shiny hair. Damaged hair regains a natural, healthy appearance. Wet and dry combability are improved, and further damage to the hair cuticles is prevented.
