Abstract

A liquid bandage is a topical skin treatment for minor cuts and sores aiming at protecting the wound from external aggressions and at creating an environment favorable to the healing process. Several liquid bandage solutions can be found on the market. Those products are usually mixtures of chemical compounds having the ability to create a polymeric layer that binds to the skin. Such a polymer layer protects the wound by keeping dirt and germs out, and keeping moisture in. [1]

A liquid bandage is generally based on a polymeric material which is dispersed or dissolved in a volatile solvent. Additional ingredients such as plasticizers are often found in liquid bandage solutions to improve the film properties of the polymeric material. When a liquid bandage solution is applied at the skin surface, the solvent evaporates quickly, forcing the polymer material to form a film that adheres to the skin surface. Silicone-based materials can be considered as ideal ingredients for the development of liquid bandage solutions. Indeed silicone film-forming polymers have the ability to form continuous, flexible films with optimal adhesion to the skin surface. They are easily dispersible or solubilized in organic or silicone solvents, and can be then easily incorporated in common liquid bandage solutions.

1.      Formulation description

A basic liquid bandage formulation can be obtained by dispersing or solubilizing a polymeric material in a volatile solvent. The ratio between the polymer and the solvent usually varies from 5/95 to 60/40 polymer/solvent. The optimal ratio is determined based on the desired properties of the film and the application system (e.g. spray versus brush).

More complex liquid bandage formulations can be achieved by blending different polymers dispersed or solubilized in a solvent together and/or by adding plasticizers to the polymer/solvent mixture to im...
