Personal care formulations

Personal care and hygiene formulations for topical application to mucosal surfaces. These formulations include an amphiphilic lipid carrier in the form of a colloidal composition which can include a micellar aggregate or mixed micelles dispersed in a continuous aqueous phase, or an emulsion of lipid droplets suspended in a continuous aqueous phase, and an active agent which is an anti-microbial agent. The lipid carrier has high adhesiveness to mucous membranes such as the soft tissues of the oral cavity. The lipid carrier also has a high load capacity for the active agent to be carried to these tissues. These formulations have the desirable properties of carrying a large amount of active agent for controlled and prolonged release thereof at the desired site, such as mucous membrane surfaces and surrounding tissue. Accordingly, the present invention provides a formulation for oral or topical application including an anti-microbial agent and a lipid. The agent is held by the carrier through a hydrophobic interaction and is released from the carrier in a controlled manner over a prolonged period of time. The lipid is also characterized by having a high adhesive capability towards mucous membrane surfaces. The lipid and the agent are preferably present in a ratio in a range of from about 1:10 to 10:1, more preferably from about 1:5 to about 5:1, and most preferably from about 1:3 to about 3:1 in the formulation.

The present invention discloses a composition and method of providing ionic forms or compounds of any combination of three metals to produce a product that can be used as a antimicrobial as defined by the U.S. Environmental Protection Agency (EPA) such as a hard surface disinfectant and as a foliar spray or water treatment for the control of various diseases in garden row, field and tree crops, on hard surface areas such as equipment from infected fields or in hospitals, homes, etc. as well as against a wide range of human, plant and animal diseases. Additionally, the composition of the present invention is able to be used to coat and otherwise treat and disinfect food products such as but not limited to fish and shellfish, meat, milk, poultry, eggs and irrigated crops (both food and nonfood crops) as well as non food products as defined in the EPA exemption from tolerance for copper and copper products. The composition may include inerts such as surfactants, detergents and buffers to adjust the pH. The composition remains soluble in water and is useful efficacious against the spread of bacteria, viruses and fungi and other pathogens within a source of water such as a reservoir or pool. Alternatively, the composition may be in aerosolized, misted, vaporized, fogged, humidified forms to produce micronized particles which are able to remain in suspension in the air for long periods of time in order to act on air-borne fungal spores and/or pathogens.

Microbicidal formulations and methods to control microorganisms

Microbicidal formulations are described which are preferably ecologically friendly and non-toxic to mammals, and are highly effective against a broad spectrum of detrimental pathogenic microorganisms. The microbicidal formulation contains complexes having the formula R-M, wherein R is at least one organic chelating moiety and M is at least one metal ion which is microbicidal to at least one microorganism. These complexes can disrupt microorganism activities by penetrating the natural protecting bio-films of such microorganisms through the reaction of the R-group with the organic constituents of these microorganisms while releasing M into their intra-cellular media. Thus, this process exhibits its biocidal activities from the inside-out, contrary to other methods which rely on damaging the protective biofilms. These microbicidal formulations can be diluted in suitable proportions into aqueous systems to produce the desired dosages for each individual case, depending on the level and the severity of the contamination. The microbicidal formulations can be applied by conventional methods, e.g., spraying, soaking, fogging, impregnation, and the like. The formulations can also be used as preservatives, such as for fresh or cut flowers and plants. These microbiocides can also be made as gel or solids in different forms by using techniques available to those skilled in the art.
