  • Patent number: 6214913
    Abstract: A method and product which provides a solid, non-powdered homogeneous form to liquid and low melting point solid compounds which facilitates stability, storage, dispersability and handling and which may be added directly to formulations requiring the liquid compound or low melting point solid compound. The liquid or low melting point solid ingredient is combined with a binder which is comprised of at least a wax and thermoplastic polymer. During the method of forming the product, both the binder and the liquid compound (or low melting point solid compound) pass through a liquid phase during which they are mixed. The product is then formed and cooled.
