20080255290 | Method of Dust Abatement - A method of dust abatement, including applying and reapplying to a surface having particulate material a single-phase solution including a water-soluble polymer selected from the group consisting of polyvinyl alcohol, derivatives thereof, and combinations thereof, at a rate of 0.1 g/m to 6 g/m | 10-16-2008 |
20090004373 | Methods and Compositions for Temporary Barrier Coatings - Methods of temporarily protecting an exterior surface of a structure, an interior hard surface, and an automobile part, including the step of applying to the surface a solution including a water-soluble polymer, and allowing the solution to dry, thereby forming a water-soluble polymer coating on the surface, is disclosed. The protective coating can thereafter be removed by washing the surface with water, such as with a power sprayer, taking with it any secondary substance which has coated it or otherwise has been bound to it. | 01-01-2009 |
20090035426 | CARBOXYMETHYL CELLULOSE-BASED FILMS AND EDIBLE FOOD CASINGS MADE THEREFROM - An edible film useful for applying a flavoring additive to a food item is disclosed. The edible film generally includes an edible carboxymethyl cellulose film-forming resin and an edible plasticizer. The carboxymethyl cellulose film-forming resin is preferably a blend of two different carboxymethyl celluloses having different molecular weights. The edible film preferably includes additional additives, for example an edible surfactant and an edible tackifier. The edible film can suitably accept a food flavoring ingredient to form a flavored film that can be used to apply a flavor to a food item. | 02-05-2009 |
20100105821 | Water-Soluble Film - A film-forming composition made from a mixture of PVOH, chitosan, an alkali metal or ammonium bisulfite or metabi sulfite, and optional ingredients such as plasticizers, antioxidants, UV stabilizers, surfactants, crosslinking agents, lubricants, and extenders, is disclosed. Also disclosed are a method of making a film from the composition, a resulting film, and a packet made from the film and containing a cleaning composition such as a rinse additive. The composition can be formulated to yield an article such as a film which is soluble only below a predetermined pH threshold. | 04-29-2010 |
20110186467 | WATER-SOLUBLE FILM HAVING IMPROVED DISSOLUTION AND STRESS PROPERTIES, AND PACKETS MADE THEREFROM - Disclosed is a pouch having at least one sealed compartment containing a first composition. At least one wall of the at least one sealed compartment is made from a water-soluble film having any suitable thickness. The water-soluble film comprises PVOH polymer such that when the film has a thickness of about 76 microns the film is characterized by a Dissolution Index of about 620 to about 920, or of about 665 to about 920, or about 710 to about 920; and a Stress Index of about 145 to about 626, or about 155 to about 480, or about 165 to about 325. | 08-04-2011 |
20110186468 | WATER-SOLUBLE FILM HAVING IMPROVED DISSOLUTION AND STRESS PROPERTIES, AND PACKETS MADE THEREFROM - Disclosed is a pouch having at least one sealed compartment containing a first composition. At least one wall of the at least one sealed compartment is made from a water-soluble film having any suitable thickness. The water-soluble film comprises PVOH polymer such that when the film has a thickness of about 76 microns the film is characterized by a Dissolution Index of about 620 to about 920, or of about 665 to about 920, or about 710 to about 920; and a Stress Index of about 145 to about 626, or about 155 to about 480, or about 165 to about 325. | 08-04-2011 |
20110188784 | WATER-SOLUBLE FILM HAVING BLEND OF PVOH POLYMERS, AND PACKETS MADE THEREFROM - Disclosed are plasticized, water-soluble films having favorable cold-water solubility, wet handling, and thermoforming characteristics, and which can include a PVOH resin made up of blend of two or more PVOH polymers each having a monomodal molecular weight distribution, and the PVOH resin characterized by a viscosity in a range of about 13.5 cP to about 20 cP (or a corresponding weight average molecular weight), a degree of hydrolysis of about 84% to about 92%, a polydispersity index value in a range of about 1 to about 5, a residual water content of about 4 wt. % to about 10 wt. %, and a Resin Selection Index value in a range of 0.255 to 0.315; methods of making the films; compositions including PVOH resins for making the films; and pouch and packet articles made from the films. | 08-04-2011 |
20110189413 | WATER-SOLUBLE FILM HAVING BLEND OF PVOH POLYMERS, AND PACKETS MADE THEREFROM - Disclosed are plasticized, water-soluble films having favorable cold-water solubility, wet handling, and thermoforming characteristics, and which can include a PVOH resin made up of blend of two or more PVOH polymers each having a monomodal molecular weight distribution, and the PVOH resin characterized by a viscosity in a range of about 13.5 cP to about 20 cP (or a corresponding weight average molecular weight), a degree of hydrolysis of about 84% to about 92%, a polydispersity index value in a range of about 1 to about 5, a residual water content of about 4 wt. % to about 10 wt. %, and a Resin Selection Index value in a range of 0.255 to 0.315; methods of making the films; compositions including PVOH resins for making the films; and pouch and packet articles made from the films. | 08-04-2011 |
