Kolliwax® SA

As lipophilic lubricant Kolliwax® SA is the first choice for sensitive acidic APIs. It is commonly also used as viscosity regulator for oil-in-water emulsions and as a pH independent sustained release agent. Kolliwax® SA acts as a plasticizer with included consistency factor in solid dispersions. It hardens suppository formulations and adjust their melting points.

Why choose Kolliwax® SA?

  • Fully approved pharmaceutical-grade excipient – for your peace of mind
  • Pasticizer with included consistency factor functionality
  • Lipophilic lubricant and the first choice for sensitive acidic APIs
  • Viscosity regulator with a higher melting point
  • Guaranteed performance across a wide variety of applications
  • Innovative solutions for better, more stable formulations

Major Applications of Kolliwax® SA

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® SA 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® SA is mainly used as structure-building consistency factor for semi-solids such as creams, emulsions, ointments and gels as well as a viscosity regulator with a higher melting point.

Kolliwax® SA is a lipophilic lubricant and the first choice for sensitive acidic APIs. As solid lubricant it is suitable for direct compression, wet granulation and roll compaction of tablets and capsules.

In solid dispersions, Kolliwax® SA also acts as plasticizer with an included consistency factor functionality. It is suitable for melt granulation, spray drying and hot melt extrusion (HME) processes.

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