BELSIL® RG 100 elastomer gel is an organosiloxane polymer dispersed in cyclopentasiloxane. It is a semitransparent gel that functions as a thickener in formulations while delivering smooth applications. Under shear stress BELSIL® RG 100 thins and allows easy incorporation of cosmetic ingredients like pigments.

BELSIL® RG 100 is easy to distribute on skin and gives a nice, non-greasy, silky skin feel. Evaporation of
the volatile silicones leave a non-tacky film, which improves the water resistance of formulations.

  • INCI Cyclopentasiloxane, Dimethicone/Vinyltrimethylsiloxysilicate Crosspolymer

BELSIL® RG 100 is a non-emulsifying elastomer gel that is supplied as a 20% active solution in cyclopentasiloxane. It provides a substantive hydrophobic film, making it ideal for use in sun care formulations. In lipsticks and foundations, it improves transfer resistance. It also can add a cushiony feel to powder formulations. BELSIL® RG 100 makes cosmetics easier to apply by adding lubricity. It can be used to thicken the oil phase of emulsions or anhydrous cosmetic formulations.

The viscosity may increase during storage, and agitation may be required before use if stored for an extended period of time.


The "Best use before end date" of each batch is shown on the Certificate of Analysis.
