Disinfectant compositions and methods of use thereof

Disinfectant compositions and methods of use thereof description/claims

This Application claims the benefit under 35 U.S.C. 1119(e) of U.S. Provisional Application No. 60/720,811 filed Sep. 27, 2005.

The present invention relates generally to an environmentally friendly, non-toxic, food grade, disinfectant composition that can be used for multiple applications including, but not limited to, uses as a mouthwash, skin cleanser, or as a germicidal for disinfecting surfaces such as foodstuff, plant matter, leather, wood, metal, plastic and fabrics.

A number of products have been developed for the purpose of disinfecting and cleaning. However, many of these products use toxic, poisonous chemicals that are detrimental to the environment and to our health.

Hydrogen peroxide is a strong, environmentally friendly, disinfectant with a broad spectrum of antimicrobial activity that has been widely used in the healthcare field. Unfortunately, hydrogen peroxide is also a strong oxidizing agent that in high concentrations can damage tissue and damage surfaces such as foodstuff, making them more vulnerable to pathogenic penetration.

Essential oils, are natural products known to have antimicrobial properties and disinfectant solutions based on essential oils have been formulated, U.S. Pat. No. 6,846,498. However, the potency and spectrum of action of many of these formulations lag behind those exhibited by other antimicrobials. Furthermore, formulations are difficult to make because the oils are not readily miscible in water.

The present invention is directed to disinfectant compositions and their use.

The invention provides a disinfectant composition comprising hydrogen peroxide (H2O2), orange terpene oil, orange valencia oil, a non-ionic emulsifier (e.g. polysorbate 80), and deionized or distilled water (H2O). The composition can include varied amounts of each of these ingredients.

In one embodiment, the orange terpene oil is present in the composition from 5% to 40% v/v, the orange valencia oil is present in the composition from 5% to 40% v/v, the non-ionic emulsifier is present in the composition from 5% to 50% v/v, the distilled or deionized H2O is present in the composition from 5% to 80% v/v and the hydrogen peroxide is present in the composition from 1.5% to 8% H2O2 w/v. In another embodiment, the composition comprises one half as much non-ionic emulsifier (e.g. polysorbate) by volume as the combined volume of orange valencia oil and orange terpene oil.

In one preferred embodiment the disinfectant composition comprises 5.25% H2O2 (15% of a 35% hydrogen peroxide solution), 10% v/v orange terpene oil, 5% v/v orange valencia oil, 10% v/v polysorbate 80, and 60% v/v distilled water.

In one embodiment, the disinfectant composition further comprises an antioxidant preservative of H2O2 such as oil of rosemary.

In one embodiment, the composition further comprises antimicrobials such as quaternary ammonium compounds, triclosan, cetyl pyridium chloride, domiphen bromide, zinc compounds, sanguinanine soluble pyrophosphates, fluorides, alexidine, octonidine, and EDTA. In addition, the disinfectant composition can also comprise surfactants, common builders that improve surfactant effectiveness, saponifiers, chelating agents, and/or other solvents.

The invention provides a method for disinfecting surfaces comprising applying the composition to the surface.

The invention further provides a method for reducing the number of mold spores on a surface. The method comprises contacting the surface containing the mold spores with the composition.
