It is an elastomer gel built as a silicone copolymer network blended with cyclopentasiloxane. It appears as a transparent, slightly yellow gel providing a very pleasant sensorial sensation during the application and after use. BELSIL® REG 102 can act as a thickener in formulations. In addition it exhibits shear thinning behavior, which allows formulating cosmetic products that spread easily during application and facilitates the incorporation of pigments into a formulation.
