Abstract
A process for utilizing gel compositions containing thickening agents which are primarily long chain organic powders in combination with small amounts of auxiliary polar thickeners having no metallic cations are described. They are particularly suitable for use as electrode gels in applications where long term contact of the electrodes with the skin is necessary. The process utilizing the described gel compositions, unlike the gels known to the art will not irritate the skin, corrode the electrodes, dry out in only a few hours or leak out from the electrode.
Claims3
The process of electrical stimulation which comprises the steps of:
- a. applying a perspiration-resistant gel composition comprising a major proportion of water
- from 1/20th of 1 wt. % to 10 wt. % of a long chain water soluble ionic polymeric thickener having a Brookfield viscosity (CPS) of approximately 1,000 to 100,000 at a 1 wt. % concentration in H.sub.2 O, which has been neutralized with an alkali metal hydroxide,
- from 1/1,000 of 1 wt. % to 3 wt. % of a cellulosic backbone auxiliary thickener having no metallic ion constituent which has at least one primary hydroxy group attached to each repeating unit in the cellulose backbone having a 1 wt. % solution viscosity (Brookfield) at 25.degree. C. of from 100 to 10,000 and
- from 10.5 to 25 wt. % of a polyol humectant wherein said gel has a pH of between 3.5 to 11.5, to the surface of an animal, including humans,
- b. firmly contacting the resulting gel area with at least one metal electrode,
- c. applying a galvanic force between said electrode and said surface.
