Title: Guido Joseph Danhieux: Innovator in Dye Chemistry
Introduction
Guido Joseph Danhieux is a notable inventor based in Charlotte, NC (US). He has made significant contributions to the field of dye chemistry, holding 2 patents that showcase his innovative approach to dye compositions and their applications.
Latest Patents
One of his latest patents is for a Bunte salt azo dye compound. This invention relates to a dye composition that includes an azo dye containing at least one Bunte salt group. The resulting dye is a water-soluble material that is useful for the rapid dyeing of both natural and synthetic fibers. Notably, the Bunte salt azo dye can be used without requiring a mordanting step or a concurrent or pre-reducing step, allowing fibers of animal hair to accept the dye effectively and achieve strong color performance.
Another significant patent is for stable liquid suspensions and a method for analyzing them. This patent provides stable, pourable aqueous suspensions of solid particulate materials, particularly sulfur dyes. These suspensions are characterized by a very low content of inorganic sulfides and polysulfides. The suspensions are produced using specific suspension stabilizing agents, such as polysaccharides like xanthan gum. An improved method is also provided for determining the potential of these suspensions to release hydrogen sulfide upon acidification.
