Abstract
An aqueous composition with a higher-than-neutral pH includes a significant amount of one or more surfactants and large amounts of osmotically active solutes. This composition, as well as an acidic counterpart and solid materials, can be used in a variety of applications such as wound care, oral care, medical equipment reprocessing, healthcare acquired infection and implant treatment.
Claims20
A process for reducing bacterial colonization in or around the area of a chronic ulcer, said process comprising, during the inflammation stage of healing, applying to said area a gel that comprises at least one PEG and an aqueous composition having a pH of from 2 to 4, a total solute concentration of from 1.8 to 4.0 Osm/L, and from 0.9 to 1.7 g/L of at least one cationic surfactant, said gel being free of sporicides, antifungals and antibiotics.
A process for reducing bacterial colonization in or around the area of a chronic ulcer, said process comprising, during the inflammation stage of healing, applying to said area a gel that consists essentially of at least one PEG, an aqueous composition having a pH of from 2 to 4, a total solute concentration of from 1.8 to 4.0 Osm/L, and from 0.9 to 1.7 g/L of at least one cationic surfactant, and optionally one or more of an emollient, a lotion, a humectant, a glycosaminoglycan, an analgesic, colloidal silver and a coalescent.
A process for reducing bacterial colonization in or around the area of a chronic ulcer, said process comprising, during the inflammation stage of healing, applying to said area a gel that comprises
- a) at least one PEG and
- b) a composition having a pH of from 2 to 4 and a total solute concentration of from 1.8 to 4.0 Osm/L that consists essentially of
- (1) water,
- (2) a buffer system that comprises of one or more organic acids and at least one salt of one or more organic acids, and
- (3) from 0.9 to 1.7 g/L of at least one cationic surfactant,
- said gel being free of materials having antimicrobial properties other than those provided by said composition.
