BELSIL® RG 90 is easy to distribute on skin and gives a nice, silky skin feel. The evaporation of isododecane leaves a non-tacky film which improves transfer- and water resistance of cosmetic formulations. Elastomer gel BELSIL® RG 90 shows thixotropic behaviour. It undergoes thinning under shear stress and allows easy incorporation of cosmetic ingredients like pigments.

BELSIL® RG 90 is a non-emulsifying elastomer gel that is supplied as a 20% active elastomer in isododecane. It can be formulated in O/W, W/O and W/Si-emulsions as well as in anhydrous systems. The preferred way of incorporation into a formulation is to disperse BELSIL® RG 90 in suitable oils and solvents. Alternatively, it can be added to the finished formulation. It provides a silky skin feel combined with hydrophobic film forming properties. These benefits are applicable in skin care, sun care and color cosmetic formulations. BELSIL® RG 90 can improve water repellence of sun screen formulations. In color cosmetic applications like lipsticks and foundations, it improves transfer resistance. It also adds a cushiony feel to powder formulations like eye shadows.

The viscosity may increase during storage, and agitation may be required before use if stored for an extended period of time. Due to the thixotropic behaviour, the initial viscosity may be reduced by mechanical impact like stirring.


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

Storage beyond the date specified on the Certificate of Analysis does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
