Humectant

Abstract: A stable aqueous hydrogen peroxide gel dentifrice for oral anti-gingivitis application having an acid pH of about 3-6 comprising a combination of hydrophilic and hydrophobic fumed silica gelling agent, hydrogen peroxide, about 20-40% by weight of a polyethylene glycol humectant, flavor, sweetening agent, sodium benzoate, and a nonionic surfactant as the essential ingredients, prepared by a process which comprises controlling the order of addition of the essential ingredients. Distilled (deionized) water is preferred in the formulation to prevent minimal contamination.

Abstract: This invention relates to a non-stringy adhesive hydrophilic gel comprising an aqueous mixture of a radiation crosslinkable water-soluble polymer, at least one humectant effective to extend the moisture retaining characteristics of the gel and which inhibits the ability of radiant energy to crosslink the water-soluble polymer, a pharmacologically active agent, and a crosslinking promoter effective to counteract the crosslinking inhibitory effect of humectant. The aqueous mixture is exposed to radiant energy effective to provide a non-stringy adhesive cohesive homogeneous hydrophilic gel that has an extended in-use lifetime. The gels can be formed into PATCHES for long term application of the pharmacologically active agent to a patient.

Abstract: 1. AN INK COMPOSITION CONSISTING ESSENTIALLY OF AN AQUEOUS SOLUTION OF 0.5 TO 7.0% BY WEIGHT OF A WATER-SOLUBLE DIRECT DYE AND 5 TO 40% BY EIGHT OF A HUMECTANT SYSTEM FORMED OF A MIXTURE OF A LOWER ALKOXY TRIGLYCOL AND AT LEAST ONE COMPOUND SELECTED FROM THE GROUP CONSISTING OF A POLYETHYLENE GLYCOL HAVING AN AVERAGE MOLECULAR WEIGHT UP TO ABOUT 600, POLYPROPYENE GLYCOL HAVING AN AVERAGE MOLECULAR WEIGHT UP TO AOUT 425, A LOWER ALKYL ETHER OF ETHYLENE GLYCOL AND DITHYLENE GLYCOL, PROPYLENE GLYCOL AND GLYCEROL, WITH THE WEIGHT RATIO OF THE ALKOXY TRIGLYCOL TO SAID COMPOUND BEING WITHIN THE RANGE OF 0.1 TO 3.0, THE INK COPOSITION HAVING A VISCOSITY WITHIN THE RANGE OF 1.0 TO 10 CENTIPOISE AT 25*C. AND A SPECIFIC RESISTIVITY LESS THAN 150 OHM-CM.

Abstract: A stable aqueous hydrogen peroxide dental gel for oral cleaning and anti-gingivitis application having an acid pH of about 4.5-6, comprising about 18-25% by weight of a solid flake or powder poly-oxyethylene polyoxypropylene block copolymer gelling agent, hydrogen peroxide, about 15-40% by weight of a polyethylene glycol humectant, flavor, or sweetening agent such as sodium saccharine, and a nonionic surfactant, as the essential ingredients. Distilled (deionized) water is preferred to prevent minimal contamination.
