A solvent for oral, topical applications, co-emulsifier and low HLB surfactant, structure-building consistency factor for semi-solids and a viscosity enhancer. It also hardens suppository formulations and adjust their melting points.
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.
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.
