    Kolliwax® GMS II

      Kolliwax GMS II is widely used as a co-emulsifier and consistency building factor. On the account of its consistency giving characters it is mainly used for the viscosity adjustment in pharmaceutical O/W emulsions. Kolliwax® GMS II is a white to slightly yellowish, hydrophilic wax, which is supplied as powder. BASF has in-depth knowledge about how to utilize this material and how best to manage its performance and its stability.

    Why choose Kolliwax® GMS II?

    Major applications of Kolliwax® GMS II

    • Emulsions

        Kolliwax® grades can be used for all kinds of topical pharmaceutical applications such as gels, lotions and creams. All Kolliwax® grades act as consistency factors and co-emulsifiers at the same time. With their amphiphilic structure they will stabilize the surface between oil and water and will help to enhance the viscosity with building up a liquid crystalline network in the water-phase (lamellar structure).

        Kolliwax® is able to stabilize W/O and O/W emulsion and will help top create a unique softness and creaminess in the end application. Kolliwax® GMS II acts as co-emulsifier and low HLB surfactant. It stabilizes the surfactant phases & emulsion droplets. It is suitable for production of emulsions & creams, ointments, gels and foams.

      Consistency factor


        Kolliwax® GMS II is used as solvent for oral and topical applications. It is suitable for solutions, liquid suspensions and lipid-based drug delivery systems technologies.


        As co-emulsifier and viscosity enhancer Kolliwax® GMS II is used in capsule fill formulations.

      Suppository mass

        Suppository formulations can be hardened and adjusted in their melting point by the addition of Kolliwax® GMS II.
