Product description

BELSIL® DM 0.65 is a colorless, clear fluid of low viscosity and high volatility. It is non-polar and insoluble in water but miscible with alcohols, esters, and other solvents frequently utilized in cosmetics. Due to its low heat of vaporization, BELSIL® DM 0.65 evaporates from the skin without producing a cooling or stinging effect. BELSIL® DM 0.65 evaporates rapidly and without residues.


BELSIL® DM 0.65 can be utilized as a delivery system in antiperspirant and deodorant formulations as well as hair-care products and color-cosmetic compositions.

It helps to uniformly spread actives and pigments over the surface of hair and skin. It provides sufficient play time in color-cosmetics applications, thereby improving rub-in properties, reducing stickiness, and imparting lubricity and a smooth skin feel.

In hair-care products BELSIL® DM 0.65 supports easy spreading of high-viscosity fluids, improves wet combability, and functions as a resin plasticizer in fixative styling products.

To adjust drying times for specific product requirements, BELSIL® DM 0.65 may be blended in all proportions with other dimethicones and cyclomethicones.
