Ozokerite wax is generally a white, crystalline, odorless and tasteless solid. It is most often made from blends of paraffin and microcrystalline waxes, and when combined offers broader functionality than the constituent ingredients. It is used extensively in personal care and cosmetic formulations. It will increase viscosity, assist in emulsion stability and enhance gel strength in liquid and semi-solid systems. It is a hard wax with a relatively high melting point. These characteristics encourage its use in lipstick and lip care products to promote structure and stick strength.
