Ternary and quaternary wax-resin composites for use in cosmetic and pharmaceutical preparations

A process for making a cosmetic composition comprising the steps of:

• (a) at least partially solvating hydrogenated polycyclopentadiene in a solvent under the application of heat in the range of 80-85° C. resulting in a resin-solvent blend;
• (b) preparing a composition of wax, wherein said wax comprises at least one abhesive wax having a melting point range of 55° C. to about 115° C.;
• (c) mixing said resin-solvent blend and said wax to form a wax-resin blend;
• (d) removing the solvent from said wax-resin solution to produce a solid wax-resin composite;
• and
• (e) blending said wax-resin composite with materials selected from the group consisting of pigments, pharmaceuticals, oils, esters and sunscreens.

A method for producing a solid wax-resin composite comprising:

• (a) melting hydrogenated polycyclopentadiene resin;
• (b) blending together the melted hydrogenated polycyclopentadiene resin with waxes at a temperature sufficient to melt the waxes, said wax comprising at least one of a first wax selected from the group consisting of crystalline polyethylene waxes, synthetic waxes, hydrocarbon waxes, petroleum waxes and mixtures thereof, and a second wax selected from the group consisting of natural or synthetic waxes containing hydrocarbons or hydrocarbon-like structures;
• (c) allowing the blended hydrogenated polycyclopentadiene resin and waxes to solidify into a wax-resin composite;
• and
• (d) post-processing the wax-resin composite to form slabs, pastilles, flakes or other solid forms.
