A linear, non-reactive, unmodified polydimethylsiloxane. It is a Dimethicone with a viscosity of 60000 mm²/s. BELSIL® DM 60000 is characterized by low surface tension and a high spreading coefficient. Due to their flexible polymer backbone, dimethicones have high permeability to gases (e.g. water vapor, oxygen), which allows respiration of the skin.
