Description
Technical Field
The present invention relates to aqueous cleaning compositions comprising anionic surfactant, nonionic surfactant and organic acid and to methods and uses thereof for cleaning and disinfecting surfaces.
Background
Cleaning products are well known and play an important role in everyday life. Such products will contain surfactants and, if disinfection is desired, disinfectants (e.g., chlorine bleach), quaternary ammonium compounds (e.g., benzalkonium chloride) or chloroxylenol. Such conventional disinfectants appear to be effective against a wide range of microorganisms, however, these disinfectants have been reported to potentially affect human health.
Personal hygiene (i.e., how to care its own body) is traditionally distinguished from household care (including laundry and home care), which includes cleaning hard surfaces such as toilets, floors, and countertops.
More and more consumers prefer cleaning products with good environmental characteristics. That is, they are preferably "environmentally friendly" and have little or no impact on the environment when the product is used. Accordingly, there is an increasing demand for cleaning products that contain primarily or exclusively natural and/or biodegradable components. It is also desirable that the product be formulated to avoid disinfectants such as chlorine bleach, quaternary ammonium compounds such as benzalkonium chloride or chloroxylenol, and the like, while still providing disinfection benefits.
Organic acids such as citric acid and lactic acid are natural alternatives to synthetic disinfectants such as chlorine bleach, benzalkonium chloride and chloroxylenol. These organic acids exhibit antibacterial action, but may not themselves exhibit broad-spectrum antibacterial action, i.e., against gram-negative bacteria (e.g., escherichia coli and pseudomonas aeruginosa) and gram-positive bacteria (e.g., staphylococcus aureus and enterococcus hirae). Bacteria such as enterococcus hirae are known to be more difficult to combat. Furthermore, antiviral effects may be limited in potency and/or breadth, e.g., only against enveloped viruses and not against non-enveloped viruses. Non-enveloped viruses are known to be more difficult to combat.
In this regard, WO2004/18599 discloses acidic hard surface compositions comprising an acidic component comprising a water soluble organic acid, at least one anionic surfactant ingredient, at least one nonionic surfactant, at least one organic solvent ingredient, optionally one or more further ingredients and the balance water, which provide cleaning and disinfecting benefits. The composition exhibits surprising efficacy against a variety of gram positive and gram negative types of pathogenic bacteria, as well as against fungi in the absence of known cationic quaternary ammonium compounds known to be effective against pathogenic bacteria, and excludes other known prior art antimicrobial ingredients and bleaching agents.
In view of the foregoing, there remains a need for cleaning compositions having good environmental characteristics without compromising consumer satisfaction in terms of performance and disinfection efficacy against bacteria and/or viruses.
Disclosure of Invention
We have found that a specific combination of organic acid, anionic surfactant and nonionic surfactant allows the use of organic acid as a natural disinfectant while the cleaning composition exhibits broad spectrum antimicrobial efficacy. We have also found that the composition has antiviral properties.
Accordingly, in a first aspect, the present invention relates to an aqueous cleaning composition comprising:
0.1 to 10 wt% of an anionic surfactant selected from the group consisting of alkyl sulfates, alkyl ether sulfates, and combinations thereof;
0.1 to 10 wt% of a nonionic surfactant selected from the group consisting of alcohol ethoxylates, short chain alkyl polyglycosides, and combinations thereof; and
from 1 to 20% by weight of an organic acid having a pKa of from 2.5 to 5.5;
wherein the composition has a pH of 2 to 4;
wherein the alcohol ethoxylate has 1 to 7 EO; and is also provided with
Wherein the alkyl polyglycoside has a C8 to C10 alkyl group,
wherein the composition is free of organic solvents.
The invention further relates to a method of cleaning a surface comprising the step of contacting said surface with a composition of the invention in pure or diluted form for at least 15 seconds.
The invention also relates to the use of the composition of the invention for disabling bacteria on a surface.
The invention also relates to the use of the composition of the invention for disabling viruses on surfaces.
Detailed Description
Any feature of one aspect of the invention may be used in any other aspect of the invention. The word "comprising" is intended to mean "including", but not necessarily "consisting of …" or "consisting of …". In other words, the listed steps or options need not be exhaustive. Except in the operating and comparative examples, or where otherwise explicitly indicated, all numbers in this description indicating amounts of material or conditions of reaction, physical properties of materials and/or use are to be understood as modified by the word "about". The numerical range expressed in the form of "x to y" is understood to include x and y. When multiple preferred ranges are described in the format of "x to y" for a particular feature, it is to be understood that all ranges combining the different endpoints are also contemplated. Unless otherwise indicated, amounts used herein are expressed in weight percent based on the total weight of the composition and are abbreviated as "wt-%". The use of any and all examples, or exemplary language, e.g., "such as", provided herein is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention otherwise claimed. Room temperature is defined as a temperature of about 20 degrees celsius.
Aqueous cleaning composition
The cleaning composition of the present invention is an aqueous cleaning composition, that is, the composition comprises water. The amount of water will depend on the desired concentration of the other ingredients but is at least 50 wt%, for example at least 60 wt% or at least 70 wt%, but typically no more than 99 wt%. The amount of water is preferably 50-98 wt.%, more preferably 60-95 wt.%, even more preferably 70-90 wt.%.
The composition is liquid, i.e. it can be poured and has a viscosity of 1 to 1000mpa.s@20s-1 at 25 ℃. Viscosity was measured using an AR 1000 rheometer (TA instruments) using a 4cm,2℃cone plate geometry at 20s-1 and 25 ℃. The compositions may have a higher or lower viscosity depending on the desired use characteristics. For example, if the composition is to be used in a trigger spray bottle, a more dilute (water thin) viscosity is required. If dispensed from squeeze bottles, a more viscous consistency may be desired. A more viscous viscosity may also be desirable if the cleaning product is a toilet cleaning product. Preferably, the composition has a viscosity of 100 to 700mpa.s@20s-1, more preferably 200 to 600 mpa.s@20s-1. The desired viscosity may suitably be obtained by known methods, for example using viscosity modifiers.

Use of the same
The antimicrobial efficacy of the compounds can be determined using several protocols, of which EN1279 and EN13697 are most commonly used. EN1279 is a so-called suspension test, and EN13697 is a so-called surface test. For household hard surfaces, EN13697 is a better indicator. We have found that some known cleaning compositions do not always exhibit the desired antimicrobial efficacy when tested according to EN 13697.
The invention also relates to the use of a composition according to the invention for disabling pathogens on a surface. The specific combination of anionic surfactant, nonionic surfactant and organic acid allows for broad antimicrobial efficacy without the need for synthetic disinfectants.
