H-Sil® D4 is a volatile cyclic dimethyl silicone fluid that is clear and odorless. This low-toxicity solvent evaporates completely at room temperature and leaves no residue. It is widely used in cosmetics to provide spreading, easy rub-out, and a slick, non-greasy feel to the skin. It is a good cleaning solvent for industrial applications with degreasing properties for dry cleaning and spot treatment applications.
