DISINFECTANT COMPOSITION.

Abstract

A disinfectant cleaning composition, substantially free of quaternary ammonium antimicrobial actives, the composition comprises: a bispyridinium alkane antimicrobial active and a specific polymer.

Description

The present invention falls within the field of disinfectant compositions, particularly the field of disinfectant cleaning compositions. The composition provides biocidal residual activity while simultaneously providing good cleaning and shine. BACKGROUND OF THE INVENTION Compositions such as those described in patent no. WO 2016 / 086012 Al provide long-lasting disinfectant benefits. However, surfaces treated with such compositions may be left with a poor gloss profile, slow drying time, and a sticky / adherent feel that suggests a lack of cleanliness to the user. Patent No. WO2013 / 098547 describes an antibacterial composition comprising quaternary ammonium compounds for sanitizing or disinfecting surfaces. These compounds tend to deposit on the surface as a visible residue, leaving the user with the impression that the treated surface has not been properly cleaned. This is because the surface appears streaked and lacks a glossy finish. Furthermore, the treated surface may feel slightly sticky, further contributing to the user's impression of poor cleanliness. Additionally, quaternary ammonium compounds typically interact with the cleaning surfactants present in the composition. The result is a reduction in the composition's antimicrobial efficacy, or the requirement for higher levels of the antimicrobial active ingredient. The use of high levels of quaternary ammonium antibacterial actives in cleaning products may be undesirable for environmental reasons.Another disadvantage is that its level is restricted in products used on food contact surfaces. Therefore, there remains a need for a disinfectant composition that provides good cleaning, shine, and long-lasting disinfection. Ideally, the composition would be suitable for surfaces that come into contact with food. BRIEF DESCRIPTION OF THE INVENTION According to the first aspect of the present invention, a disinfectant cleaning composition is provided. The composition comprises a bispyridinium alkane antimicrobial active and a polymer. The composition provides biocidal residual activity. According to the second aspect of the invention, the composition of the invention is used to provide biocidal residual activity to a surface, in particular a hard surface. According to the third aspect of the invention, an article 5 is provided, treated with the composition of the first aspect of the invention. The article is in the form of a disposable or partially reusable substrate comprising one or more nonwoven layers. The article provides sanitization to surfaces, particularly hard surfaces. The article is sometimes referred to herein as the article of the invention. The elements of the composition of the invention described in relation to the first aspect of the invention apply mutatis mutandis to the other aspects of the invention. rnfrnnn / zznz / E / YiAi DETAILED DESCRIPTION OF THE INVENTION All percentages, ratios, and proportions used in this description are expressed as a percentage by weight of the composition, unless otherwise specified. All average values ​​are calculated by weight of the premix, unless otherwise specified. All ratios are calculated as a weight / weight level, unless otherwise specified. All measurements are taken at 25°C, unless otherwise specified. Unless otherwise stated, all component or composition levels refer to the active portion of that component or composition and exclude impurities, for example, residual solvents or by-products, which may be present in commercially available sources of such components or compositions. As used in this description, the terms microbe or microbial should be interpreted to refer to any of the microscopic organisms studied by microbiologists or found in the environment of use of a treated article. Such organisms include, but are not limited to, bacteria and fungi, as well as other single-celled organisms such as mold, mildew, and algae. Viral particles and other infectious agents are also included under the term microbe. The term "antimicrobial" should also be understood to encompass both microbicidal and microbiostatic properties. That is, it includes the elimination of microbes, leading to a reduction in their number, as well as a retarding effect on microbial growth, where the numbers may remain more or less constant (but still allow for a slight increase or decrease). For ease of description, this description uses the term antimicrobial to denote broad-spectrum activity (e.g., against bacteria and fungi). When discussing efficacy against a particular microorganism or taxonomic range, the more focused term will be used (e.g., antifungal to denote efficacy against a particular fungal growth). Using the example above, it should be understood that efficacy against fungi does not in any way preclude the possibility that the same antimicrobial composition may demonstrate efficacy against another class of microbes. Residual biocidal properties refer to achieving at least 99.9% microbial reduction in the 24-hour Residual Self-Disinfection (RSS) test methodology approved by the Environmental Protection Agency (EPA) for dry product residues on hard, non-porous surfaces (EPA No. 01-1A). That is, the compositions of the invention exhibiting residual biocidal properties can provide at least 99.9% microbial reduction after a 24-hour test regime of 12 abrasions and 5 reinoculations. rnfrnnn / zznz / E / YiAi Disinfectant composition The present invention relates to a disinfectant composition. The composition comprises a bispyridinium alkane, preferably octenidine dihydrochloride, and a polymer. The composition may also include a carrier, preferably water, a surfactant, a pH adjuster, and a fragrance, among other components. Preferably, the composition is in liquid form, more preferably as an aqueous solution. Preferably, the composition comprises more than 80%, more preferably more than 90%, and especially 95 to 99% by weight of water. The composition is preferably alkaline and has a pH of 9 to 14, preferably 10 to 13. The composition is formulated with surface disinfectant and residual biocidal properties for at least 24 hours, through the provision of at least 99.9% microbial reduction in the EPA-approved 24-hour RSS test method (EPA No. 01-1A). The composition can be applied to a surface by spraying, rolling, fogging, wiping, or other means. The composition acts as a surface disinfectant, eliminating infectious microbes present on the surface for at least 24 hours. Once dry, the liquid formulation leaves a protective film on the surface. This film has biocidal properties, allowing it to maintain surface protection against microbial contamination for an extended period after application. The disinfectant composition creates a film capable of rapidly eliminating bacteria and other germs for at least 24 hours after application to the treated surface. Rapid elimination generally refers to a period of approximately 30 seconds to 5 minutes. The film remains on the surface and is resistant to repeated touches and surface wear. After application, the surface exhibits a good gloss profile. Antimicrobial agent The composition of the invention includes bispyridinium alkanes, such as those described in patent no. GB1533952.

Such materials tend to have higher molecular weights than most nonionic surfactants, and as such may range from 1000 to 30000 g / mol, although the molecular weight should be greater than 2200 and preferably less than 13000 to be in accordance with the invention. A preferred range for the molecular weight of the polymeric nonionic surfactant is from 2400 to 11500 daltons.

(3) Cleaning of baked / polymerized grease on glazed surfaces. Formulations are applied to a sponge, and the number of cleaning strokes is recorded for complete soil removal. The number of strokes is then indexed against a standard hard surface cleaner (index 100), with a higher index indicating better cleaning.
