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.
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).
