DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to antimicrobial compositions which can be used to disinfect and clean various surfaces including animate surfaces (e.g., human skin, mouth and the like) and inanimate surfaces including, but not limited to, hard surfaces like wails, tiles, table tops, glass, bathroom surfaces, kitchen surfaces, dishes as well as fabrics, clothes, carpets and the like.
BACKGROUND
Antimicrobial/antibacterial compositions include materials which have the ability to disinfect. It is generally recognised that a disinfecting material greatly reduces or even eliminates the micro-organisms, e.g., bacteria, existing on a surface. Compositions based on halogen containing compounds like hypochlorite, or on quaternary compounds, have been extensively described in the art for disinfecting purpose. Compositions comprising peroxide bleach are also known as disinfecting compositions.
However, compositions based for example on peroxide bleach as the only antimicrobial compound (typically 7% by weight of the total composition), are not fully efficacious, especially when used upon highly diluted conditions, e.g. at a dilution level of 1:50 (composition:water) to disinfect soiled surfaces, e.g., surfaces which needs both to be washed and disinfected. Indeed, the presence of organic and/or inorganic soils decreases the bactericidal activity of many antimicrobials like peroxygen bleach, resulting thereby in a lower bactericidal activity/disinfection power of compositions comprising them.
It is thus an object of the present invention to provide compositions which deliver excellent disinfection on soiled surfaces, especially heavily soiled surfaces, even when used upon highly diluted conditions.
It has now been found that this can be achieved by combining different antimicrobial compounds together, i.e., by combining a peroxygen bleach, an amphoteric surfactant, or a mixture thereof, glutaraldehyde and an antimicrobial essential oil or an active thereof, or mixtures thereof. More particularly, it has been found that a composition comprising said peroxygen bleach, said amphoteric surfactant, said glutaraldehyde and said antimicrobial essential oil or active thereof provides excellent disinfection on soiled surfaces including heavily soiled surfaces, even under highly diluted conditions, i.e., up to a dilution level of said composition to water from 1:100.
An advantage of the present invention is that excellent disinfection is provided under soiled conditions on a broad range of bacterial strains including Gram positive and Gram negative bacterial strains but also more resistant micro-organisms like fungi.
Another advantage of the compositions of the present invention is that beside the disinfection properties delivered, good cleaning performance is also provided.
Also, the compositions according to the present invention are suitable to be used on all types of surfaces including animate surfaces (e.g., human skin and/or mouth when used as an oral preparation or toothpaste) and inanimate surfaces. Indeed, this technology is particularly suitable in hard-surfaces applications as well as in laundry applications, e.g., as a laundry detergent or laundry additive in a so called "soaking mode", "through the wash mode", or even as a laundry pretreater in a "pretreatment mode". More particularly, the compositions according to the present invention are suitable to be used on delicate surfaces including those surfaces in contact with food and/or babies in a safe manner. Indeed, when using the compositions according to the present invention in diluted conditions, the amount of chemical residues left onto a surface disinfected therewith is reduced. Thus, it may be not necessary to rinse for example a hard-surface after the compositions of the present invention have been applied thereto in diluted conditions.
Yet another advantage of the compositions of the present invention is that they may be provided in different forms, e.g., in a liquid form packaged in a conventional detergent bottle, or in a sprayable or f
