INCI name

BELSIL® DM 5 is a linear, non-reactive, unmodified polydimethylsiloxane.

BELSIL® DM 5 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.
