Patent number: 8877882Abstract: Liquid adhesive coating materials are prepared that protect surfaces, such as medical devices and biological surfaces, including skin and mucous membranes, from pressure, shear, and friction. The liquid coating materials utilize an amphiphilic siloxysilane/hydroxyalkyl ester polymer-containing coating material dissolved in a volatile solvent, with or without an antimicrobial agent, where when the polymer coating is formed after solvent evaporation and is folded against itself or placed against another material, the surface of said coating does not adhere, while the bottom of the coating remains attached to the original surface.Type: GrantFiled: October 4, 2013Date of Patent: November 4, 2014Assignee: Rochal Industries LLPInventors: Joseph Charles Salamone, Katelyn Elizabeth Reilly, Ann Beal Salamone, Xiaoyu Chen

Patent number: 8852648Abstract: A composition and method adapted for delivery of hydrophilic, biologically-active agents are disclosed. The composition can include a reverse microemulsion formed from at least one hydrophilic, biologically-active agent solubilized by a hydrophobic reverse emulsion surfactant in a non-stinging, volatile, hydrophobic solvent. The non-stinging, volatile, hydrophobic solvent is selected from the group consisting of volatile linear and cyclic siloxanes, volatile linear, branched, and cyclic alkanes, volatile fluorocarbons and chlorofluorocarbons, liquid carbon dioxide under pressure, and combinations thereof. The reverse microemulsion can be an optically clear solution.Type: GrantFiled: October 21, 2013Date of Patent: October 7, 2014Assignee: Rochal Industries, LLPInventors: Joseph Charles Salamone, Xiaoyu Chen, Ann Beal Salamone, Katelyn Elizabeth Reilly

Patent number: 8829053Abstract: An antimicrobial composition with synergistic biocidal activity is described which comprises at least one antimicrobial polymeric biguanide and at least one antimicrobial vicinal diol, said vicinal diol comprises at least one monoalkyl glycol, monoalkyl glycerol, or monoacyl glycerol, to diminish or eliminate biofilm communities. Such synergistic interaction is effective in wound treatment, particularly for chronic wounds, burns and battlefield-induced wounds, as well as for disinfecting non-biological surfaces. The antimicrobial composition can also be prepared as viscous solutions or as gels. The antimicrobial composition may be added to a substrate and dried, such as to a catheter, or to a foam, or to a fiber wound dressing, or coated as a viscous solution or gel upon such devices, to provide controlled release antimicrobial activity.Type: GrantFiled: December 7, 2011Date of Patent: September 9, 2014Assignee: Rochal Industries LLPInventors: Joseph Salamone, Ann Beal Salamone

Patent number: 8784793Abstract: A biological coating material that includes a polymerizable polyacrylate monomer; a volatile liquid; a polymer selected from a synthetic rubber, a natural rubber, and a thermoplastic elastomer. The biological liquid coating material forms a coating or bandage in the form of a film that when applied and adhered to a surface or to the skin of a user inhibits the application surface from adhering to another surface.Type: GrantFiled: July 22, 2013Date of Patent: July 22, 2014Assignee: Rochal Industries, LLPInventors: Ann Beal Salamone, Joseph C.

Patent number: 8263720Abstract: Combinations of solubilized, covalently crosslinked, siloxy-containing polymers in a solvent system of a volatile hydrophobic (non-polar) liquid that is non-stinging to a user are excellent non-irritating liquid coating materials for forming films, which, after solvent evaporation, are water insoluble but water-vapor permeable and lightly adherent to surfaces such as skin and mucous membranes. The crosslinking content is greater than 1 weight % and can be as much as 16 weight %. In comparison to non-crosslinked polysiloxy films, or crosslinked films of 1 weight % or less, the enhanced crosslinked polysiloxy films, while continuing to be soluble in the solvent, have reduced tack and reduced adhesion to skin and can act as sacrificial coatings under strongly adherent pressure sensitive adhesives.Type: GrantFiled: October 5, 2011Date of Patent: September 11, 2012Assignee: Rochal Industries, LLPInventors: Joseph Salamone, Ann Beal Salamone, Xiang Yu, Levi J.
