$BELSIL<sup>®</sup> EG 1200

BELSIL® EG 1200 elastomer gel is a non-emulsifying silicone gel composed of a cross-linked silicone elastomer copolymer network which has been swollen with a non-volatile, low viscosity (5cSt) dimethicone. BELSIL® EG 1200 has a rather high viscosity but can be easily further diluted with silicone fluids or organic solvents allowing a broad flexibility when formulating cosmetic products.

BELSIL® EG 1200 is a clear to translucent gel, which provides pleasant sensory properties.

  • INCI Dimethicone, Dimethicone Crosspolymer


BELSIL® EG 1200 can add consistency and a nice silky texture to cosmetic formulations. Due to its rather high viscosity BELSIL® EG 1200 can act as a thickener in formulations while delivering a smooth application. Typical for elastomer gels, BELSIL® EG 1200 exhibits a shear-thinning behavior. Cosmetic formulations containing BELSIL® EG 1200 can be spread easily during application and leave a very pleasant silky feel. In addition, BELSIL® EG 1200 acts as a carrier for fragrances allowing a slow release of the fragrance.

BELSIL® EG 1200 is added to the oil or silicone phase of a formulation. When formulating a W/O emulsion the elastomer gel can also be added to the already formed emulsion. In both cases, a good homogenization is needed to ensure that the elastomer gel is well mixed into the oil phase or the final emulsion. A short time of stirring is sufficient, but as the cross-linked silicone elastomer network is stable, also longer homogenization steps are possible. When BELSIL® EG 1200 is diluted with silicone fluids or organic solvents, the viscosity of the product decreases significantly and can be easily adjusted.

During the application BELSIL® EG 1200 shows a pleasant silky sensory profile. It also provides a nice texture and a comfortable cushion effect especially after the application. These performance properties make it of BELSIL® EG 1200 a versatile ingredient for various Skin Care, Color Cosmetic and Hair Care products. Typical applications for BELSIL® EG 1200 are facial creams and lotions, foundations and moisturizing creams. BELSIL® EG 1200 can be used to thicken the oil phase of emulsions or anhydrous cosmetic formulations in pressed powder cosmetics it acts as binder.


BELSIL® EG 1200 is a high viscose material. However due its highly shear-thinning behavior, it can be pumped with suitable equipment. Upon storage, the apparent viscosity BELSIL® EG 1200 may increase. However, the viscosity data can vary significantly depending on how the product is stirred prior to measurement. WACKER recommends to thoroughly mix BELSIL® EG 1200 before any viscosity measurement. If the product is stored for an extended period of time, it should be re-mixed prior to use.


The 'Best use before end' date of each batch is shown on the product label.

Storage beyond the date specified on the label 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.
