Definitions
- 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 walls, tiles, table tops, glass, bathroom surfaces, kitchen surfaces, dishes as well as fabrics, clothes, carpets and the like.
- animate surfaces e.g., human skin, mouth and the like
- inanimate surfaces including, but not limited to, hard surfaces like walls, tiles, table tops, glass, bathroom surfaces, kitchen surfaces, dishes as well as fabrics, clothes, carpets and the like.
- 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.
- compositions comprising hydrogen peroxide as the only antimicrobial agent, typically at a level of 7% by weight of the total composition, are not fully satisfactory when used upon high dilution levels, e.g. at a dilution level of 1:50 (composition: water) to disinfect clean surfaces, i.e., surfaces which are substantially free of organic and/or inorganic residues.
- WO88/00795 discloses liquid disinfecting compositions comprising a compound selected from the group of organic acids, perborates, peracids and their salts, together with other antimicrobial compounds like a quaternary ammonium salt and an essential oil.
- liquid compositions comprising a bleaching agent and an essential oil
- traditional essential oils are usually made by a blend of components including terpenes, esters, aromatic components, chetones, aldehydes and the like.
- Said essential oils are sensitive to peroxygen bleaches.
- said essential oils show significant instability in presence of peroxygen bleaches and tend to decompose / oxidise said peroxygen bleaches, therefore leading to a lowering of the total level of available oxygen in a composition comprising a peroxygen bleach with consequent chemical stability issues upon long storage periods.
- It is therefore an object of the present invention to provide a liquid disinfecting composition comprising a peroxygen bleach which is chemically stable for long storage periods while delivering excellent disinfection performance on clean surfaces when used upon highly diluted conditions.
- liquid peroxygen bleach-containing composition comprising on top of said peroxygen bleach, an antimicrobial active of essential oil or mixtures thereof. More particularly, it has been found that the liquid peroxygen bleach-containing compositions of the present invention comprising said antimicrobial active of essential oil, exhibit improved chemical stability upon long storage periods, as compared to the same compositions comprising antimicrobial essential oils instead of said antimicrobial active of essential oils, while providing also excellent disinfection on clean surfaces, i.e. surfaces being free of any organic and/or inorganic soils, even at high dilution levels, i.e. up to dilution levels of from 1 :100 (composition:water).
- An advantage of the present invention is that excellent disinfection is provided on a broad range of pure bacterial strains including Gram positive and Gram negative bacterial strains and more resistant micro-organisms like fungi.
- compositions of the present invention are that beside the disinfection properties delivered, good cleaning is also provided, especially in the embodiment of the present invention where the compositions herein further comprise a surfactant and/or a solvent.
- 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.
- EP-B-288 689 discloses a liquid for hard-surfaces comprising antimicrobial effective amounts of pine oil and at least one oil soluble organic acid. No other antimicrobial compounds are mentioned, let alone a peroxygen bleach.
- EP-241390 discloses that textiles contaminated with bacteria may be disinfected by first treating with a detergent and then with a peroxide bleaching agent in an aqueous bath at pH 9-13 in the presence of non complexed calcium. No other antimicrobial compounds are disclosed, let alone antimicrobial actives of essential oils. US-4,404,191 discloses that per-compounds such as monopersulfate have bactericide, fungicide and virucide properties. US-4,404,191 discloses that compositions comprising monopersulfate may be used in diluted form to treat hard-surfaces. However no other antimicrobial compounds are disclosed, let alone antimicrobial actives of essential oils.
- US-5,403,587 discloses aqueous antimicrobial compositions which can be used to sanitise, disinfect, and clean hard-surfaces. More particularly, US- 5,403,587 discloses aqueous compositions (pH 1 to 12) comprising essential oils (0.02% to 5%), which exhibit antimicrobial properties efficacy such as thyme oil, eucalyptus oil, clove oil and the like, and a solubilizing or dispersing agent sufficient to form an aqueous solution or dispersion of said essential oils in a water carrier. Said compositions may further comprise other antimicrobial ingredients like phenolic compounds, quaternary ammonium compounds, however no betaine or sulphobetaine surfactants, or peroxygen bleaches are disclosed.
- essential oils 0.02% to 5%
- Said compositions may further comprise other antimicrobial ingredients like phenolic compounds, quaternary ammonium compounds, however no betaine or sulphobetaine surfactants, or peroxygen bleache
