Abstract: An electrochemical process for the preparation of water-soluble colorants, particularly triphenylmethane colorants and other water soluble technical dyes, is disclosed. In this process, the anode in the electrochemical cell comprises an open pore carbon material having specific void volume and surface area characteristics. A preferred electrode material is a carbon felt pad, preferably between about 1/16 inch and ¼ inch in thickness. This process provides faster reaction rates than electrochemical processes using standard electrodes, as well as higher yields compared to processes using chemical oxidizing agents.

Abstract: System for the electrochemical cleavage of compounds which includes a mediator which has no metals or heavy metals and at least two electrodes for the electrochemical activation of the mediator.

Abstract: Electro-osmotic (or electrokinetic) transport is used to efficiently force a solution (or water) through the interior of the fibers or yarns of textile materials for wet processing of textiles. The textile material is passed between electrodes that apply an electric field across the fabric. Used alone or in parallel with conventional hydraulic washing (forced convection), electro-osmotic transport greatly reduces the amount of water used in wet processing. The amount of water required to achieve a fixed level of rinsing of tint can be reduced, for example, to 1-5 lbs water per pound of fabric from an industry benchmark of 20 lbs water/lb fabric.

Abstract: A method of introducing therapeutic, cosmetic, and dyeing agents in buffer medium created by the electrophoretic flow of these solutions into the hair. The result is to increase the therapeutic effect of treatments for the hair including hair growth and regeneration. Other results include the even and stable dyeing of hair due to the increased adhering properties created through the electrophoretic device and the solutions used with it. These solutions include, but are not limited to, those dyeing and therapeutic agents which do not readily stick to the hair or those which may form unstable compounds.
