Title: The Innovations of Paul A. Hanna
Introduction
Paul A. Hanna is a notable inventor based in Queens Village, NY (US). He has made significant contributions to the field of encapsulated particles, holding a total of 3 patents. His work has implications in various cleaning compositions, particularly in automatic dishwashing detergents.
Latest Patents
One of his latest patents involves wax-encapsulated particles. These solid core particles are encapsulated in a single coat of paraffin wax, which has a melting point of about 40 to 50 degrees Celsius. The solids content ranges from 100% to about 35% at 40 degrees Celsius and from 0% to about 15% at 50 degrees Celsius. The paraffin coat can comprise 20% to 90% by weight of the particle and may vary in thickness from 100 to 1,500 microns. This innovative coat prolongs the time in which the encapsulated particles remain active in aqueous environments. The encapsulated particles are created by spraying molten wax onto the particles in a fluidized bed. These wax-encapsulated particles can be incorporated into liquid or powder cleaning compositions, particularly automatic dishwashing liquid detergents, at a concentration of 0.01% to 20% by weight of the composition.
