Abstract
A method of creating a bulk product that includes a surface layer of specialized content is based upon the use of an excipient with a different surface tension such that self-differentiating of the excipient from the bulk during drying/curing transports the specialized material to the surface of the bulk product. When the excipient has a lower surface tension than the bulk material, the difference in surface tension causes the low surface tension material to rise to the top surface, bringing the specialized material along. Alternatively, if the excipient has a higher surface tension than the bulk material, it will transport the specialized material to the bottom surface of the product.
Claims6
A method of creating a specialized coating layer on a product transforming into final solid form from a liquid/slurry initial stage, comprising the steps of:
- a) providing a bulk product material in liquid/slurry form, the bulk product material exhibiting a surface tension σprod;
- b) selecting a transport liquid with a surface tension σliq that is different from σprod;
- c) dispersing a specialized material component into the transport liquid;
- d) mixing the transport liquid with the dispersion of the specialized material created in step c) with the bulk product material provided in step a), wherein the difference in surface tensions (σprod≠σliq) causes the transport liquid to entrap the specialized material in a plurality of micelles that move the specialized material to a surface of the bulk product material during transformation into its final solid form;
- and
- e) releasing the specialized material from the plurality of micelles upon reaching the surface of the bulk product material.
