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 semisolid useful for reducing bacterial contamination on skin, said semisolid comprising an organic carrier which comprises at least one of emollient and humectant and, suspended therein, an aqueous composition with a pH of greater than about 3 and less than about 4.5 which comprises ionic surfactant, said composition having a total solute concentration of at least ˜1.5 Osm/L and being free of sporicides, antifungals and antibiotics.
A semisolid useful for reducing bacterial contamination on skin, said semisolid comprising:
- a) an organic carrier which includes at least one of emollient and humectant, and
- b) an emulsified or suspended composition having a pH of greater than about 3 and less than about 4.5 and a total solute concentration of at least ˜1.5 Osm/L that comprises
- (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) more than 0.075 weight percent cationic surfactant,
- said semisolid being free of materials having antimicrobial properties other than those provided by said composition.
